plastic strip monitor housing, the PCB inside can slide out of the housing, through the top, or bottom end
to expose the various controls for adjustment.
It is important to try to avoid placing the monitor immediately beside any metal objects, such as metal
doors, electrical cables, metal cabinets etc as these can affect the performance of the door monitoring
system. Following initial setting up of the detection zone, parking of large metal objects within the field of
the system (6/8 ft) such as trolleys, beds, etc should be avoided as these will also have an effect upon the
detection field of the monitor.
2.3 Power supply
The 12Vdc ac adaptor output cable should be plugged into the wired-in strip monitor power supply cable
with jack socket and connected to the ac mains supply, when ready to power up the monitor (see Section
3 below – “Setting Up”). If using a magnetic door contact, or electric door lock, connections are
conveniently provided at the top end of the monitor. Note that when using a door lock, an ac adaptor
providing minimum 500mA at 12Vdc is required. Where the two strips are used on either side of a door
both should be connected to the door lock (in parallel) and to the magnetic door contact (in series) if
employed (see diagrams 001/1 and 001/3 for details).
2.4 External devices
An external indicating light and/or external sounder may be connected to the alarm output terminals (refer
to J18 option).
The connections for the door lock and alarm light at the top of the sensor strips have a 12V dc power
source provided and an output that pulls down to 0V via a relay contact (max 1A). Therefore, this only
requires a two-wire connection (refer to drawings 001/1 and 001/3). The rating of the ac adaptor must be
considered when connecting these external devices to the monitor and advice can be obtained from our
technical services division.
Cables for connecting the power supply, door locks, magnetic door contacts, or other external devices
should be kept as short as possible and away from the body of the monitor unit, as these will have an
effect upon field/detection zone of the system.
3.0 PROGRAMMING AND SETTING UP (please refer to drawings in Section 6)
3.1 Programming
If our DMU-02 wireless remote display unit and/or our CMU-02 wireless Central Monitor with large LCD
display is to be employed, the door monitor can be programmed to transmit an alarm with a number
identifying the particular door and area. The other programmable features are the door lock time (5
second interval settings) and the field detection zone size.
For setting up, first slide PCB out of the end opposite to the power cord. Refer to drawing 001/1.
Observe the exposed “Mode” button and door/area ID programming rotary switch.
Note: A single digit “location” code number only needs to be set if there is more than one CMU-02 on the
system and you wish to route this door monitor’s signals to only one particular monitor. In this case, the
CMU-02 would be set for a “matching” single digit (1-7) location number. Otherwise set this door monitor
rotary control to zero (0) so it can be received by any central monitor.
3.1.1 Programming door and area identity numbers
To enter “programming” mode, hold down the “Mode” button for around 3 seconds until three (3) rapid
bleeps with LED flashes are observed, then release the button.
