How to choose a warehouse intercom system
To prevent the risk of wires getting damaged in the warehouse, we advise opting for wireless public address (PA) speakers for broadcasting messages to all staff members. Additionally, individuals requiring attention can access wireless intercoms or callboxes strategically positioned across the warehouse. Alternatively, they can utilize handheld radios to promptly respond to calls.
The office will use a desktop base station wireless intercom to transmit and receive calls. It has multiple channels so you can leave it set to Channel 1, which will be the channel used to broadcast messages to the wireless PA units spread throughout the warehouse.
The intercoms in the warehouse will be set to Channel 2 and when workers call in the intercom in the office will be set to scan the channels and it will lock in on that channel so the office can talk to the warehouse worker. That way conversation can take place without being broadcast over the Wireless PA units.
In the warehouse you can use a couple of different intercoms for the workers to call back. The wireless callboxes are durable enough for outdoor use and they only have a single button so there is nothing that can get changed by employees.
The same base station used in the office can also be wall mounted at various locations in the warehouse. The downside of this is users could change the channels, but you can program it with only one channel.
At full volume setting the wireless PA units will output 102db at 12 feet away and 84db at around 100 feet so if properly located in the warehouse one PA receiver can cover a good amount of floor space. You can also centrally locate a unit and add an additional speaker to each receiver for a little greater coverage area.
Broadcasting from Phone Systems
Unfortunately, the above system cannot be used to broadcast messages from your existing phone system. It does not have an input that lets you pick up a phone handset to broadcast a PA message.
There is a Wireless PA Bridge device that allows you to use a 2-way radio to broadcast pages into an existing wired PA system. A Wireless PA Bridge receiver is designed to be connected to an existing PA/intercom system with its own PA amplifier and wired speakers. The Wireless PA Interface connects to the Aux Input of the PA system via RCA Phono Cable if it is located within six feet of the wireless PA system.
The only other option available if you want to use your phone to broadcast messages is to use a wired PA system amplifier. This will require running wires to a amplifier that is connected to a line port on your phone system. If you use a hosted phone system this will not work and you will need to contact your provider to see if they have anything available. If you do have an onsite phone system, you can use a wired PA system like this one: Wired PA System
