WIRELESS MAGNETIC CONTACT
SECURITY DETECTORS
«Ladoga MK-RK»
«Ladoga MK-RK» version 1
1 General Information
1.1 Wireless magnetic contact security Detectors «Ladoga MK-RK»
and «Ladoga MK-RK» version 1 (hereinafter, the Detectors) are
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 channel by
the «Rielta-Contaсt-R» protocol.
1.2 Opening or shifting control is fulfilled by built-in magnetic
contact monitoring. The Detectors comprise the plugs for external
inertia detectors (hereinafter, the EID) hooking up.
1.3 Two versions of Detectors are manufactured:
- «Ladoga MK-RK» – single-zone, provides a possibility for one EID
hooking up;
- «Ladoga MK-RK» version 1 – two-zone, provides a possibility for
two EID hooking up to «Loop 1» and «Loop 2».
The built-in magnetic contact and «Loop 1» are integrated in one
zone.
The built-in magnetic contact is disabled by jumper «Hermetic
Contact» (see Figure 1) applying.
1.4 Detectors operate within 433.05 – 434.79 MHz frequency range.
Their transmission power does not exceed 10 mW.
1.5 The Detectors ensure 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 Detectors 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 Detectors are powered from main (СR123А) and backup
(СR2032) power supply batteries.
1.8 Operation modes of the Detectors are displayed by a two-color
LED indicator. The detector «Ladoga MK-RK» version 1 provides
complementary sound indication of the Detector state.
1.9 The Detectors generate and transmit the following messages:
- «Norm» – under closed built-in magnetic contacts in «Loop 1» or
resistance value in «Loop 1» less than 3.4 or more than 6.9 kΩ;
- «Intrusion to Zone 1» – under opened built-in magnetic contacts
in «Loop 1» or resistance value in «Loop 1» less than 3.4 or more than
6.9 kΩ;
- «Intrusion to Zone 2» (only for «Ladoga MK-RK» version 1) – under
resistance value in «Loop 2» less than 3.4 or more than 6.9 kΩ;
- «Tamper» – in the event of case tampering or removal from the
installation surface;
- «Main Power Supply Low Battery» – under the main power supply
battery voltage drop over 2.8-0.4 V;
- «Backup Power Supply Low Battery» – under the backup power
supply battery voltage drop over 2.8-0.4 V.
1.10 The Detectors are designed to operate continuously, around
the clock.
1.11 The Detectors have 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), built-
in hermetic contact (3), jumper for disabling of built-in magnetic
contact (5), tamper (4), two-color LED indicator (7), terminal blocks
for EID hooking up (8), main battery holder (9), «RESET» contacts
(11). There is a sound indicator situated on the face side of the
«Ladoga MK-RK» version 1. The backup power supply battery holder
and the wall tamper are located on the reverse side of the PCB. 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 control. The magnet should be installed opposite to
the recess in the sidewall of the base.
Figure 1
5 Indication
The following types of indication are generated by the Detectors:
a) «Binding» – procedure of logging of the Detector in the CP;
b) «Identification» indication is activated by relevant commands re-
ceived from the CP and deactivated after the Detector cover is closed
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.
Sound indication (only for «Ladoga MK-RK» version 1) is activated
by the relevant command from the CP.
The types of LED indication are listed in the Table 3.
