RQT-152 VHF quick talk transmitter for wireless alerting

RQT-152 VHF quick talk transmitter for wireless alerting

This unit connects up to four switch or sensors to the RQT switch input and records a unique voice message for each of the 4 switches. In the event that the status of a switch changes, the pre-recorded message will immediately be transmitted to all personnel equipped with a radio. Additionally, each input can be programmed to transmit on different frequencies.

The RQT radio works with radio repeaters and its range can be extended with a RAM-1545 antenna.

The device is encased in gasket-sealed, polycarbonate enclosure, which is fitted with built-in mounting flanges. It can either operate as a stand-alone using 6 AA batteries or powered externally through the use of a 110V AC adapter RPX-Expo.

Key features include:

  • 2 watt VHF (150-165 MHz)
  • PC programmable
  • Built-in microphone for voice recording
  • Models: UHF 450-470MHz, VHF 150-165MHz, VHF MURS License-Free
