4-channel keychain receiver
Miniature four-channel receiver RR-701RM4 is part of the RIF RING-701 radio control and alarm equipment and is designed to receive alarm signals from several (maximum of four) portable radio buttons or stationary transmitters over the radio channel RIF RING-701 and RIF STRING-200 systems with sound and light signals. Alarms for any loop are received (but not distinguished) from the multi-zone transmitters of the RIF STRING-200 system, and the signals REMOVED and RECEIVED from these transmitters are ignored. The RR-701RM4 receiver can be used for remote alarm notification at facilities, for transmitting personal call signals to employees on the territory of an enterprise, for calling a bodyguard or driver in an extreme situation using a portable alarm radio button and other similar tasks.
Before use, the transmitters must be registered in the receiver's memory using a learning procedure. The training is conducted over the air without additional equipment.
The range of receiving alarm radio signals from stationary transmitters in line-of-sight conditions reaches 3 km. The actual transmission range depends on the type of transmitter and its antenna, on the presence of obstacles to the propagation of radio waves (walls, ceilings, buildings, dense vegetation, terrain), on how the owner wears the receiver, on the intensity of radio interference in a given place and at a given time, etc.>
