Wireless PA receivers work with all VHF, UHF, MURS, GMRS and FRS radio frequencies. For even greater flexibility, each wireless PA receiver can be set to your existing two-way radio network on channels that are not already in use. Installation is quick and easy; simply plug in the included AC-to-DC power adapter and you are ready to go with true plug-and-play operation.
Below are some of the most frequently asked questions about industrial wireless PA systems and two-way radio PA systems.
Wireless PA FAQs
A: Use the RT1118 Wireless PA system with base station transmitters. It covers approximately 7,500 sq. ft per unit, depending on obstructions. You’ll need power outlets for each PA, and possibly an electrician for installation. Intercoms are not installed by the seller.
Q: What options are available for an emergency paging solution in a warehouse after losing a Polycom phone system?
A: Possible solutions include: (1) a wireless PA system such as the RT1118 MURS
UHF/VHF/GRMS/FRS Wireless PA System, paired with MURS Multi-Mile Base
Wireless Intercoms for multiple microphones; (2) if retaining an IP
phone system, using a SIP multicast paging adapter like the VK1026 to connect to the current amp and speakers; or (3) connecting a wireless PA interface such as the RT1120 to the PA system to allow broadcasts via two-way radios or base station intercoms.
Q: What
are the options for a wireless PA system for an indoor cashier to
communicate with an outdoor truck scale with no power nearby?
A: The wireless PA system
requires 12 volts. You can run low-voltage wiring from a nearby outlet
or install a solar power system, such as the MURS Solar Power System, to
operate it.
Q: What wireless PA system is
available for emergency notification across an industrial campus, and
does it integrate with existing alarm systems?
A: IntercomsOnline does not offer a Wi-Fi PA system but does have the RT1118 radio
frequency wireless PA system, which works with base station intercoms
or two-way radios. It does not integrate with other alarm or
notification systems.
Q: What is the best way
to update handheld two-way radios and add a wireless PA for a 4-story
concrete building with interference issues?
A: The RT1118 wireless
PA works with UHF, VHF, GMRS, and MURS. UHF is better for indoor use,
but coverage in multi-story concrete buildings should be tested before
full deployment. Recommended radios include license-free BT1001, DA1006, and RT1014.
For UHF radios, repeaters can improve coverage but add complexity and
typically handle only one channel, possibly requiring multiple units.
You can start with radios and PA, then add repeaters as needed (Not for
use with MURS radios). The wireless PA can be programmed to work with
current radios. No installation services are provided.
Q: What is a possible upgrade to replace up to 40-line phones with a wireless paging system for a manufacturing plant?
A: The RT1118 Wireless
PA System is recommended. It uses two-way radios and a base station
intercom for one-way broadcasting. Additional devices like a voice
evacuation system can be integrated.
Q: What is a cost-effective wireless PA solution for a 65,000 sq ft warehouse?
A: Multiple RT1118 wireless
PA receivers can be used, each covering about 7,500 sq ft in open
space. Adding an extra speaker to each receiver and aiming in opposite
directions increases coverage. All units can be on the same channel,
broadcasting from a device like the RT1014 MURS commercial wireless intercom. Additional horn speakers and RCA Y-connectors are available.
A: No, RT1118 PA speakers cannot be operated over Wi-Fi. They require two-way radios for communication, with range dependent on the environment. Intercoms Online does not offer a Wi-Fi/app-based solution for unlimited-distance operation.
A: The recommended solution is the RT1118 one-way loud receiver paired with a transmitter such as the RT1014 MURS Commercial Wireless Intercom. This setup allows the front of house to speak into a microphone, and the message will be broadcast clearly to the kitchen without requiring a response.
A: A VoIP phone system, such as Grandstream, is required. For paging integration, a SIP multicast paging adapter with amplifier may be needed. IntercomsOnline does not sell or support full VoIP phone systems, so installation and programming should be handled by a local provider.
Q: What wireless intercom and
speaker system is suitable for a 43,000 square foot warehouse needing
paging from the office and two-way communication with workers, loud
enough to be heard over forklifts?
A: The RT1118 wireless PA system is recommended for the speakers, paired with the RT1014 MURS
Commercial Wireless Intercom for office paging. While paging is
one-way, additional base stations can be placed in the warehouse on the
same channel to allow two-way communication. The system uses radio
waves, so the speakers and intercom units communicate wirelessly. The
speakers are loud enough for warehouse environments with forklifts. For
coverage, 1 receiver for around 7000 square feet is advised, so 6 units
sounds correct.
A: No, IntercomsOnline stations are not compatible as replacements for Nutone apartment stations. Nutone systems typically use 4 wires, while the discussed unit uses 2. Since Nutone is out of business, replacement parts may only be found on secondary markets like eBay.
A: A wireless setup is recommended. For PA receivers, the RT1118 can be used. For transmitters, the RT1014 and BT1001 are suggested.
Q: Can a customer service button be integrated into an existing PA system, and what equipment is needed?
A: Integration is possible only if the PA system is radio-based. In that case, a wireless bridge is required. The button can signal both walkie-talkies and the PA system if all radios are on the same frequency. The recommended bridge (RT1120) is available at: https://www.intercomsonline.com/vhf-murs-uhf-grms-frs-radio-to-pa-bridge . For retail store use, MURS call boxes are best since they are license-free, unlike UHF which requires an FCC license. For a 50,000 sq. ft. indoor space, for example, the 120mW version is sufficient.
A: The RT1118 does not directly work with other speakers, but you can use the RT1120 Wireless PA Bridge. This connects to a standard PA amplifier, which drives the speakers, allowing the wireless PA bridge to broadcast messages through them.
Q: What intercom or communication system can support mobile staff and six production lines needing fixed stations?
A: The RT1118 Wireless PA system can be set up across production lines, allowing broadcasting to staff via handheld radios or base station intercoms. RT1014 base stations can be placed at each line for responses, and handheld radios such as the BT1001 can be used for mobile staff. This provides effective two-way communication.
Q: What intercom or PA system should be used if only one-way communication is required?
A: The RT1118 Wireless PA System is recommended for one-way announcements across multiple buildings. Two-way communication options are more limited, especially for wireless systems that can call individual areas separately. For that need, no reliable commercial wireless solution is available at this time.
Q: What system can a club use to alert staff when someone arrives at an unattended service window, with an indicator that stays on until acknowledged?
A: A MURS Indoor/Outdoor Customer Service Callbox (RT1024) with a wireless PA system is recommended. When a customer presses the call button, it can broadcast a message over the PA and can be programmed to repeat until reset. The “All Clear” or reset function is triggered by pressing the call button again, and it also resets automatically after the final message transmission.
A: If your site uses repeaters, a wireless PA system would likely require repeaters as well to achieve full coverage. You could test some handheld radios operating without repeaters to see if they reach the desired areas before implementing a full system.
A: Programming instructions are available in the LoudMouth at www.ritron.com with the privacy code table. If interference is present, first check whether it occurs on your radios as well. Changing the PA privacy code requires changing the code on the radios too.
Q: What intercom and PA system options are available for a church and preschool, and what items are recommended?
A: A wireless setup is recommended. For PA receivers, the RT1118 can be used. For transmitters, the RT1014 and BT1001 are suggested.
A: For a large construction site using two-way radios with repeaters, a wireless PA like the RT1118 would also likely need repeaters to cover the area effectively. However, it is recommended to first test radios without repeaters to see if they can provide adequate coverage before committing to that setup.
A: The RT1118 does not include a two-way radio or transmitter. The BT1001 handheld is the recommended unit to pair with it, and all compatible accessories are listed in the Related Items section on the product page.
A: Yes. The PA Bridge is designed to connect to an external wired PA amplifier through its PA inputs, allowing you to broadcast wirelessly into your own speaker system. Multiple PA Bridges can be used, and they can all monitor the same radio frequency so they activate at the same time.
A: The RT1118 wireless PA system was recommended for building-to-building communication and paging. Initial testing with BT1001 units is suggested to confirm signal coverage. Larger sites may require an external antenna for the base. Each building needs its own speaker and receiver, and the administration office requires an RT1014 base station. Outdoor units may require a weather-resistant housing. Pricing is obtained by adding items to the online cart for shipping estimates.

Q: Will our Motorola CLS1110 radios work with the wireless PA system?
A: Yes. Those radios are analog and compatible. We will need the frequency and privacy code to program them, or you can purchase a programming kit.
Q: How can I connect a PA or speaker system to my business phone system for paging?
A: You can use the VK1026 SIP Paging Adapter with Amplifier. It connects to compatible VoIP phone systems and can drive up to six speakers, or connect to a larger amplifier for expanded coverage. Most analog phone system have some sort of PA port.
Q: Is the VK1026 compatible with analog phone systems?
A: No. The VK1026 is designed for VoIP systems that support third-party SIP devices. For analog systems, different paging adapters are required.
A: The RT1118 wireless system can operate over long distances like 150–200 yards, but performance depends on factors such as building construction, metal siding, and interior and exterior obstructions, so reliable operation through a metal-sided warehouse with several walls cannot be guaranteed and may require an external antenna mounted outside the building to improve the signal. As a practical test, it is recommended that you order two BT1001 handheld radios to see if communication between the buildings is reliable at your site; if they do not work for your needs you can return them, or if they do work you can keep using them along with the PA system, and you can conveniently place the order online.
A: We do not sell the wireless PA receiver as a standalone item. The receiver is only available as part of the complete RT1118 system, which includes the horn speaker. If you need a replacement, the full RT1118 package would be required.
Q: What wireless public address system can cover a large, spread-out campus with loud outdoor horn speakers and no hard-wired connections between buildings?
A: For a widely distributed campus requiring wireless mass notification, the RT1118 wireless PA system is the recommended solution. It operates in both VHF and UHF modes, allowing flexibility based on range and interference conditions. The system supports high-output, weatherproof horn speakers designed for outdoor use, making it suitable for courtyards, walkways, and assembly areas. It delivers clear, powerful announcements over long distances without the need for inter-building cabling and can integrate well in environments that already use two-way radios.
A: Yes. The RT1118 system can support multiple speaker locations across large outdoor areas such as archery ranges, waterfronts, pavilions, fields, and cabins. The speakers can be equipped with battery backups for power outages or with solar power. If you already have two-way radios, you can use them to confirm signal coverage in each area before final placement.
A: Yes. A good solution is the RT1118 Wireless PA system: https://www.intercomsonline.com/murs-uhf-vhf-grms-frs-wireless-pa-system . This system allows you to make overhead announcements throughout the building using Channel 2. For two-way communication, you would use base station intercoms or two-way radios on a separate channel (such as Channel 1), where employees can walk up and communicate back. The RT1118 works with analog UHF or VHF radios. If your facility uses digital DMR radios, you would instead need the RT1119 DMR PA system. The PA units can be programmed to your existing radio frequency and privacy code so they work with your radios. Before installation, it is recommended to test your radios on a separate channel between the locations where you plan to install the PA speakers. If the radios communicate reliably between those locations, the PA system should also work there. If desired, you can also purchase the programming kit to program the PA systems yourself.
Q: What wireless PA system would work for a 7,500 sq ft warehouse with 2–3 speakers, and will it work if the office is about 50 feet away from the warehouse?
A: The RT1118 Wireless PA system is a good option for this application: https://www.intercomsonline.com/murs-uhf-vhf-grms-frs-wireless-pa-system . This system allows you to broadcast announcements using either base station intercoms or two-way radios. For example, you could use a base station intercom like this: https://www.intercomsonline.com/murs-commercial-wireless-intercom-1unit to send announcements to the PA speakers. A distance of around 50 feet between the office and warehouse should work fine under normal conditions. However, if the office is located inside a metal structure or shielded building that blocks radio signals, you may need to install an external antenna such as the RT1009 to improve signal reception.
Q: Can I connect a paging system to our telephone system in a warehouse, and can someone come on-site to advise us?
A: If you have an IP phone system, you can use the VK1026 SIP adapter to connect a paging system to your telephones: https://www.intercomsonline.com/sip-multicast-paging-adapter-with-amplifier. Unfortunately, we don't offer on-site visits, but whoever manages your phone system should be able to help with the installation and setup.
A: A great starting point would be the RT1118 PA system, paired with our voice notification transmitter to broadcast voice messages or alarms. For a facility that size, we'd recommend the UHF versions. You would only need one transmitter, and each PA supports up to two loudspeakers per receiver, covering areas up to 7,500 sq. ft. per speaker (each speaker includes 25 feet of speaker wire). To plan speaker placement, it's best to test your current two-way radios in every location where you want a speaker to confirm proper coverage. For office areas where bullhorn-style speakers aren't ideal, you can install a wired PA system and use the RT1120 wireless PA bridge, which receives the same wireless transmissions and converts them to work over a wired PA system.
A: We don't currently offer a device that interfaces as a cell phone-based PA system. If such a device were available, it would also require its own cell plan.
A: For a network-based paging system, the VK1026 SIP Paging Adapter with Amplifier is a good option. It can connect to your phone system and drive up to 6 loudspeakers, or connect to a larger wired PA amplifier to drive even more speakers. Since SIP is a standard protocol, it should be compatible with Avaya systems that support third-party SIP devices — but we recommend confirming that with Avaya directly to be sure.
Q: What's the most cost-effective intercom setup to communicate between our office and warehouse/yard, needing about 3-4 speakers and a base unit?
A: We recommend the RT1118 Wireless PA receivers distributed around the warehouse or yard, paired with the RT1014 MURS Commercial Base Station in the office. Each RT1118 covers about 7,500 square feet of open space, so you may need a few depending on your layout. You can also place additional RT1014 base stations around the area so employees can respond to pages. Search "RT1118" and "RT1014" on our website for full details.
Q: How many receivers and horns are included with the RT1119 DMR Digital Wireless PA System package, and does it include programming cables?
A: The DMR Digital Wireless PA System package includes one receiver and one horn. Programming cables and other accessories are optional and are not included with the standard package (see Related Items). We can also program the system for you if needed.
Q: With the RT1118 PA system and RT1014 intercoms in a school, can all classrooms hear an emergency broadcast through their intercoms, and does adding two-way communication complicate things?
A: Yes, all classrooms can hear emergency broadcasts through their intercoms. If two-way communication is not needed, simply set all RT1014 intercoms to Channel 2 and they will all receive the same broadcast. If you want two-way communication as well, set the RT1014 intercoms to Channel 1 and enable Channel Scan mode — they will still receive PA broadcasts on Channel 2. To broadcast to the PA system from an RT1014, you would switch it to Channel 2. It adds a small step but is not overly complicated.
Q: What wireless PA system would let any classroom in a small school broadcast to the whole school instantly in an emergency?
Q: I need a PA system for two large greenhouse facilities — one 700,000 sq ft and one 300,000 sq ft. What do you recommend?
Q: Can you recommend a wireless PA system compatible with our existing FRS radios, and can multiple units work together as a single system?
A: We recommend the RT1118, which is compatible with FRS radios. Full details are available here: https://www.intercomsonline.com/murs-uhf-vhf-frs-wireless-pa-system. You can add as many receiver units as needed on the same frequency, and they will function as a unified system. You will need to know the frequency and privacy code you want programmed. For standard table frequencies, no programming kit is required — you can provide us with that information and we can program the units for you, or you can change settings yourself at setup.

A: For a wireless paging system in a manufacturing facility, the recommended solution is the RT1118 system. Full product details are available here: https://www.intercomsonline.com/murs-uhf-vhf-grms-frs-wireless-pa-system. For a 50,000-square-foot facility with an open interior and operating machinery, a good starting point would be 7 receivers. Each receiver typically covers about 7,000 square feet, though coverage may be reduced in noisy environments. Each receiver can support two speakers, and adding an extra horn speaker to each receiver can improve coverage by allowing speakers to be pointed in opposite directions. The recommended components are RT1118, RT1014, RT1062, and RT1001. Additional installation information is available here: https://intercomsonline.com/v/vspfiles/downloadables/Ritron/Wireless_PA_Install.pdf. All sales and support are provided from Nashville, and Canadian versions of the equipment are available, although they are not stocked and may require up to four weeks to build. To receive a quote, place the desired items in your cart and select the "Quote" payment option during checkout. An invoice with shipping costs will be emailed to you, and no shipment will occur until payment is received.
