Quick deployment of security systems at a temporary object. Radio channel extension of alarm loop circuits of wired fire and security systems.
The equipment of Reef Ring-701 series allows building relatively simple and inexpensive systems of local address radio security. Large range of series equipment and compatibility with older series Reef String-200 allows solving various problems of security for both individuals and stationary objects. Availability of retranslator RR-701RET in the system allows expanding the coverage significantly.

COMPONENTS OF REEF RING-701
|
Receiving equipment:
- RR-701R – Receiver of alarm radio signals with LED indication (up to 8 transmitters).
- RR-701R20 – Receiver of alarm radio signals with digital indication of transmitter number (up to 20 transmitters).
- RR-701R15/4 – Receiver of alarm radio signals from transmitters, divided into four groups/zones (up to 15 transmitters).
- RR-701RМ – Hand-held receiver (pager) for radio cignal reception from one radio button or transmitter.
- RR-701RМ4 – Hand-held receiver (pager) for radio cignal reception from radio buttons or transmitters with separate sound and light indication of up to 4 transmitters.
|
Transmitting equipment:
- RR-701T, RR701TN – personal hand-held transmitters (panic radio buttons).
- RR-701TM – compact hand-held transmitter (compact panic radio button).
- RR-701TS – Stationary transmitter of alarm messages with two alarm loop circuits: with input/output delay and without delay.
- RR-701TS4 – Stationary transmitter with four independent alarm loop circuits with separate transmission of alarm messages.
- RR-701TS-L – Stationary transmitter of alarm messages with two alarm loop circuits: with input/output delay and without delay, with option to connect remote antenna.
|
Retranslators and expanders:
- RR-701RET – retranslator to extend coverage, compatible with all transmitters of Reef Ring-701 and Reef String-200.
- RR-701X-RL – expander at 10 relays for receivers RR-701R, RR-701R20, RS-201R or PCN RS-200PN, RS-201PN, RS-202PN for establishing separate output zone for each transmitter.
- RR-701X-OK – expander for 10 ouptuts of “open collector” type, operates as RR-701Х-RL.
