1 General Information

1.1 Wireless repeater CN-Repeater-AC (hereinafter, the CN-Repeater) 

is intended for operation as a part of multicomponent control panels 
(hereinafter, the CP) and for retransmission of information from wireless 
security and fire detectors or other terminal devices (hereinafter, the TD).

Retransmission is fulfilled within 433.05 … 434.79 MHz frequency 

range via a wireless two-way communication by the «CN-Contact-R» 
protocol.

1.2 Two frequencies: main and reserve are used for radio exchange 

with  the  CP.  Changeover  to  the  reserve  frequency  is  fulfilled 

automatically in case of interference at the main one. 

1.3 The transmitter radiated power does not exceed 10 mW.

1.4 The CN-Repeater is powered by AC mains with 230 V nominal 

voltage.

1.5 Reserve power is supplied by the built-in storage battery LIR14500 

type with nominal voltage 3.7 V and capacity 600 mA*h. Storage battery 

is withdrawable.

1.6 On-stream time in normal conditions with fully-charged storage 

battery in working order is not less than 24 hours.

1.7 The CN-Repeater generates and transmits by radio communication 

to CP the following messages:

- «Norm»;
- «Tamper» – in the event of case tampering;
- «

Main power supply failure

» – under main voltage supply absence;

- «Reserve power supply failure» – under storage battery discharge 

with voltage drop lower than 3.5

-0.3

 V.

1.8 The CN-Repeater fulfills storage battery additional charging (with 

exception of bootloader mode). Storage battery is not charged at battery 

voltage lower than 2.5 V and under the temperature lower than 0 °С.

1.9 Regular radio communication session period is assigned by the 

command from the CP at 10, 15, 30 sec, 1, 2, 5, 10 min intervals. 

1.10 The CN-Repeater operation modes are displayed by two LED 

indicators (see Table 3).

1.11 The CN-Repeater is designed to operate continuously, around 

the clock inside closed premises of residential buildings and production 
buildings and facilities.

1.12 The CN-Repeater is resistant to the impact of electromagnetic 

fields, electrostatic discharges and nanosecond pulse interferences.

4 Protective Measures

4.1 Exploitation of the CN-Repeater should be fulfilled in accordance 

with  rules  of  technical  exploitation  and  protective  measures  for 

 

electricity-generating equipment.

4.2 Provider of dangerous voltage in the power source is mains 

socket.

4.3 Assembling and disassembling should be fulfilled only when  

CN-Repeater is de-energized.  Storage battery should be removed.

4.4 CN-Repeater binding and quality apprising procedures should 

be carried out during storage battery power supply only.

5 Design

The CN-Repeater layout with removed cover is shown in Figure 1. The  

base (1) comprises the following elements:

- hole (6) for cover fixation;

- two holes (2) for CN-Repeater fastening to mounting surface; 
- recess (13) for power cord wiring.

Printed circuit board (PCB) (7) comprises the following elements:
- pin contacts START (3);
- contacts BOOT for USB-UART hook up (4) for firmware upgrade;

- tamper (5);
- antenna hook-up socket (8);

- green LED indicator (9);

- red LED indicator (10);
- storage battery in the holder (11);
- mains socket 230 V AC (12).

8 Switching ON and setting Up

As a general matter, operating procedure consists of the following 

steps:

- CN-Repeater binding with CP (CN-Repeater logging in the CP);

- choosing place of installation and communication quality appraising;

- CN-Repeater mounting on the place of installation.

9 Binding

9.1 Main power supply should be switched off to avid contact with 

mains socket with dangerous voltage. Binding procedure should be 
fulfilled with the CN-Repeater supplied by storage battery. The previous 

settings are deleted after binding has been finalized. 

9.2  Prepare  CP  to  logging  the  new  device  (

«Binding» procedure) 

in  accordance  with  the  CP  Manual.  During  CN-Repeater  binding 

procedure only one CP, prepared for the procedure, should be located 

in the radio coverage zone.

9.3 Untwist the screw on the CN-Repeater front side and remove 

the cover. Remove an insulator between storage battery «

+

» contact 

and holder.
