Place the infrared sensor on a wall where there is a big detection scope and at a height of 1.5m
above the ground. The sensor should face a position that possibly encounters intrusion and
there must be no obstacle in the detection scope. To install the infrared sensor, do as follows:
(1) Remove the installation base from the back of the infrared sensor.
(2) Use a pencil to mark two hole positions on the wall.
(3) Use a percussion drill to drill holes at the marked positions.
(4) Put the plastic expansion tubes into the installation holes.
(5) Use bolts to fasten the installation base on the wall.
(6) Screw down the infrared sensor on the installation base.
Temperature and humidity sensor
Install the temperature and humidity sensor on the wall at a height of 1.5m. To install the
temperature and humidity sensor, do as follows:
(1) Remove the backplane of the temperature and humidity sensor.
(2) Use a pencil to mark three hole positions for the backplane on the wall.
(3) Use a percussion drill to drill holes at the marked positions.
(4) Put the plastic expansion tubes into the installation holes.
(5) Use bolts to fix the backplane of the temperature and humidity sensor on the wall.
(6) Install the temperature and humidity sensor on the backplane again.
4. Connect sensors to the cabinet. Connect the MD68 male connector of digital signal
conversion cable to the IN port on the DEMU plane.
Use the special monitoring signal cable to connect the AIN port on the DMLC board on the
top of the cabinet and the DDF, and connect the external alarm signal connection terminals
of DDF to all sensors.
Install a DATU
board
When installing a DATU board, you need not set DIP switches on the DATU board. The method of
installing a DATU board is the same as the method of installing a DTMU board.
