Installation Guide

1 General Information

Wireless zone extension repeater «CN-Repeator» (hereinafter, the
CN-Repeator) is intended for operation as a part of multicomponent
fire control panels (FCP) and/or security control panels (SCP),
providing two-way address exchange of encoded identified signals
(messages) with wireless security and fire detectors and other terminal
devices (hereinafter, the «TD»), and retransmission of the received
information via the radio channel in the frequency range from 433.05
to 434.79 MHz by the protocol «CN-Contact-R».
C N - R e p e a t o r r e t r a n s m i t s r e c e i v e d i n f o r m a t i o n b y t h e
«CN-Contact-R» protocol ver. 6 and higher.
Total number of TD conneced to CN-Repeator is not more than 31.
CN-Repeator is powered by an external stabilized DC power supply
with nominal voltage 10...15 V.
CN-Repeator provides the possibility of hooking up to external device
(hereinafter, ED): personal computer (hereinafter, «PC») or any other
device supporting CDC-ACM interface of the virtual communication
port via USB and is intended for internal software update.

7 Switching ON and Setting up

7.1 Open cover and install antenna into terminal block.
7.2 Prepare control panel (CP) to logging the new device («Binding»
procedure) in accordance with the CP manual.
During binding procedure only one CP, which is prepared for the
procedure, should be located in the CN-Repeator radio coverage
zone. Supply 12 V on terminals «-12 V+».
7.4 Close «RESET» pin contacts located on the CN-Repeator PCB.
7.5 Assure yourself of periodical greed LED blinking («Binding»
mode). Open pin contacts.
7.6 Fulfill binding procedure in accordance with the CP manual.
7.7 Wait untill red LED indicator short-trerm blink.
Note – Binding mode is active during 100 sec since the
CN-Repeator energizing. To restart binding it is necessary to repeat
Cls. 7.5 – 7.8.
