«CN-Magnetic-Mini»

1 General Information

1.1 Wireless magnetic contact security Detector «CN-Magnetic-Mini»
(hereinafter, the Detector) is intended for opening or shifting control
of doors, windows or other structural elements with transmission of
messages to the control panel (hereinafter, CP) via two-way wireless
communication by the «CN-Contaсt-R» protocol.
1.2 Opening or shifting control is fulfilled by built-in magnetic contact
state monitoring.
1.3 The Detector operates within 433.05 – 434.79 MHz frequency
range. Transmission power does not exceed 10 mW.
1.4 The Detector ensures operation at the main and backup operating
frequencies. The changeover to backup operating frequency is fulfilled
automatically.
1.5 Radio communication is initiated by the Detector at 10, 15, 30 sec,
1, 5, 10 min intervals assigned in the process of their binding with the
CP. Alarm and tamper messages are transmitted immediately.
1.6 The Detector is powered by the one lithium power supply battery
CR123A.
1.7 The Detector generates and transmits the following messages:
- «Norm» – under closed built-in magnetic contact;
- «Alarm» – under opened built-in magnetic contact;
- «Tamper» – in the event of case tampering;
- «Power Supply Low Battery» – under the power supply battery
voltage drop over 2.2 V.
-0.2
1.8 The Detector is designed to operate continuously, around the
clock.
1.9 The Detector has immunity to electromagnetic interference.

4 Design

The Detector consists of a case cover and a base with installed printed
circuit board (PCB) (1). In the base openable fixation holes are located
in the bottom (6) and in side wall (8). The PCB comprises: battery holder
(2), RESET contacts (3), tamper contacts (4), built-in magnetic contact
(5) and antenna (7). For built-in magnetic contact management, magnet
(9) is used (supplied).

5 LED Indication

The following types of indication are generated by the Detector:
- «Binding» – procedure of logging of the Detector in the CP;
- «Identification» indication is activated by relevant commands received
from the CP, remains active during 15 min or until the Detector cover
is opened;
- LED indication of the Detector state is activated after the Detector
cover is closed and remains active during 15 min under conditions:
- other LED indication types absence;
- alarm «Tamper» message is not generated during this time;
- absence of command from the CP disabling the Detector state
indication.
The modes of LED indication are listed in Table 3.

6 Binding with the CP

The «Binding» mode is intended for the Detector logging in the CP
and service information exchange.
6.1 Prepare the CP in accordance with CP Installation Guide.
6.2 If power supply battery is installed in the holder (2), remove an
IP30
insulating film.
6.3 Periodical LED indicator blinking green is evidence of binding
process.
6.4 In case of mentioned above LED indication absence, short-circuit
«RESET» terminals for 2 – 3 sec.
6.5 Successful binding procedure complying is indicated by LED
indicator lighting red for 2 – 3 sec.
6.6 The time limit for the binding process of the Detector is 100 sec.
To restart the binding procedure, short-circuit «RESET» terminals for
2 – 3 sec.

7 Communication Quality Appraising

7.1 For radio communication quality appraising it is necessary to:
- set the Detector on the assumed place of installation;
QNT
- push and then release case tamper.
