20-channel receiver. Indication of the channel number. Supply voltage 10-15 V, 1 relay.
The RR-701R20 receiver is part of the Rif Ring-701 radio alarm system and is designed to receive radio alarms from wearable radio buttons and stationary transmitters of this system, displaying the number of the triggered transmitter, beeping and issuing alarm notifications to various reception and control devices by switching contacts. the signal relay.
It is possible to receive alarms from stationary transmitters of the Rif String-200 system.For transmitters of the Rif String-200 system, alarms are received (but not distinguished) by any loop. Up to 20 transmitters of any of these systems can be used with the receiver in any combination.
Before use, each transmitter must be registered in the receiver's memory using a learning procedure. The training is conducted over the air without additional equipment. An external expansion module with separate relays or "open collector" outputs for each transmitter can be connected to the receiver.
The transmission range of alarm radio signals from radio buttons in line-of-sight conditions reaches 1000 m, from stationary transmitters 2-3 km. The actual transmission range depends on the presence of obstacles to the propagation of radio waves, the intensity of radio interference, the type of antenna of the transmitter, etc.
An external antenna can be connected to the receiver, which significantly increases the range of the system, especially in difficult building conditions. When operating the receiver, it should be borne in mind that the power of the system's transmitters is low, and the operating frequency is allowed for use on devices from other manufacturers, so alarms can be suppressed by powerful extraneous radio signals or interference.
