Radio Modems
Connect virtually any type of switch or sensor (up to 4) to the RQT switch input(s), and record a unique voice message for each of the 4 switches. When any of the switches change state your pre-recorded voice message will instantly be transmitted to all radio-equipped personnel. Each input can be programmed to transmit on a different frequency. For extended range use the optional RAM-1545 antenna. The RQT radio even works with radio repeaters.
