Warehouse Intercom System
To keep from having to run wires all over the warehouse where they can get damaged by all the movement going on, we recommend installing wireless public address (PA) speakers to broadcast a message to all staff, and then if an individual staff member is needed, they can walk to wireless intercoms or callboxes spread throughout the warehouse to return the call. Alternatively, they can use a handheld radio to respond.
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 102dbat 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 floorspace. You can also centrally locate a unit and add an additional speaker to each receiver for a little greater coverage area.
So using these products you can build a warehouse intercom system that will solve your warehouse communication problems. If you need some assistance don't hesitate to give us a call. You can see pricing on the products below.
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
