WIRELESS MAGNETIC CONTACT
SECURITY DETECTOR
«Ladoga MK-RK» ver. 3
1 General Information
1.1 Wireless magnetic contact security Detector «Ladoga MK-RK»
ver. 3 (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 «Rielta-Contaсt-R» protocol.
1.2 Opening or shifting control is fulfilled by built-in magnetic contact
monitoring. The Detector comprises the plugs for external inertia
detectors (hereinafter, the EID) hooking up.
1.3 The Detector is – single-zone, provides a possibility for one EID
hooking up to «G 1» loop.
The built-in Gerkon and «G 1» loop are integrated in a single control
zone, operation tactics of which is set by the «ХР2» jumper (see Cl. 8).
1.4 The Detector operates within 433.05 – 434.79 MHz frequency
range. Transmission power does not exceed 10 mW.
1.5 The Detector ensures operation at the main and backup operating
frequencies. The changeover to backup operating frequency is fulfilled
automatically.
1.6 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.
1.7 The Detector is powered from the one lithium power supply
battery CR123A.
1.8 Operation modes of the Detector are displayed by a two-color
LED indicator.
1.9 The Detector generates and transmits the following messages:
- «Norm» – under closed built-in magnetic contacts and «G 1» loop
resistance value in the range 3.6 … 6.5 kΩ;
- «Intrusion to Zone 1» – under opened built-in magnetic contacts
and «G 1» loop resistance value less than 3.4 or more than 6.9 kΩ;
- «Tamper» – in the event of case tampering or removal from the
installation surface;
- «Power Supply Low Battery» – under the power supply battery
voltage drop over 2.2-0.2 V;
1.10 The Detector is designed to operate continuously, around the
clock.
1.11 The Detector has immunity to electromagnetic interference.

4 Design of the Detector
The Detector consists of a case and a printed circuit board (PCB).
On the front side of the PCB (1) there are located: antenna (2), builtin
hermetic contact (3), jumper «ХР2» (5), tamper (4), two-color LED
indicator (7), terminal blocks for EID hooking up (8), battery holder (9),
«RESET» contacts (11). The PCB is fixed on the base with a latch (10).
Magnet (6) of the inertial detector (supplied) is used for the built-in
hermetic contact supervision. The magnet should be installed opposite
to the recess in the sidewall of the base.

5 Indication
The following types of indication are generated by the Detector:
a) «Binding» – procedure of logging of the Detector in the CP;
b) «Identification»indication is activated by relevant commands
received from the CP, remains active during 15 min or until the Detector
cover is opened;
c) 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 the 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 Place the power supply battery to the holder (9) (if the battery is
installed by manufacturer, remove an isolator).
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 70 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:
- install the PCB to the base;
- set the Detector on the assumed place of installation;
- push and then release case tamper.
7.2 After case tamper releasing the Detector generates case
tamper alarm message, transmits it via radio communication channel
and represents communication quality with CP by LED indication in
accordance with the Table 4.
