DMR Digital Callbox UHF, 450-470 MHZ, Black Housing

If you have DMR Digital two-way radios like a Motorola TRBO or other brand, now there is a way to put communication anywhere you need it, even outside! Use the DRM Digital Callbox at a driveway gate, delivery dock or door, plant floor, office entrance, or almost any place you can think of. With its water resistant housing it can be placed directly in the weather. With range up to 1 mile line of sight it will handle lots of applications.

The callbox can be battery powered or powered from 12 volts DC so if you don't have power where you want to put it that's no problem.

This callbox is equipped to use pre-recorded voice messages that notify radio system users when specific events occur. These unique voice messages are recorded and stored on the callbox, and automatically played back when the associated event occurs. It supports 5 different message events.

A built in relay can be remotely activated to open a gate or release a door. A sensor input can be used for a loop sensor to open a gate, or to send a recorded voice message when a motion sensor is triggered.
