Install and provide power to the control unit. After the power supply is switched on, the state of
"FAILURE" should be shown due to the lack of connected detectors. Turn off power to the control
unit.
Mechanically fastened detectors on the object.
Connect the output of the first detector to the cable going into the control unit. The configuration
switch in the detector should be in position 2 (last detector) – see Figure 11.
The cable from a given sensor should be connected to a corresponding channel of the control unit.
After the power supply is switched on, the control unit should show the state of WORK, and the
controls on the sensor will blink subsequently for about one minute (stabilization of the sensor).
After this time, the OK indicator will light up.
If the control unit shows the FAILURE status – check and eliminate the possible connection errors.
If the control unit shows the state of WORK – perform the test of the detector operation. For this
purpose, force ALARM by pressing the TEST button in the detector. The control unit should
indicate ALARM.
Turn off the power supply.
Repeat the installation steps for further detectors.
Turn on the power supply when connecting all the detectors to the control unit. WORK should be
indicated on all the channels of the control unit. Measure the power supply voltage on the sensor
furthest from the control unit while pressing TEST. It should not be less than 10 V.
For details, see Appendix [3].
9.2.2.2 Open alarm loop
Route the main cable within the facility.
Install and provide power to the control unit. After the power supply is switched on, the state of
FAILURE should be shown due to the lack of connected detectors. Turn off power to the control
unit.
Mechanically fasten the detectors and the T-connectors on the facility. Connect the detectors with
T-connectors.
Connect the output of the first T-connector to the bus. Set the configuration switch in the detector
to 2 (working as the last detector).
After the power supply is switched on, the control unit should show the state of WORK, and the
controls on the sensor will blink subsequently for about 1 minute (stabilization of the sensor).
After this time, the OK indicator will light up.
If the control unit shows the FAILURE status – check and eliminate the possible connection errors.
If the control unit displays the status of OPERATION – the configuration switch in the detector
should be set to position 1 (working as an intermediate detector). The X1 indicator is lit in the
detector, and the control unit should signal the failure of the detector (no detector at the end of
the loop).
Turn off the power supply.
Repeat these steps for the next T-connectors and detectors.
