SERVICE:
WARNING
Isolate the Aspirating Detector from the Fire Alarm system to prevent
any unwanted Alarms when opening the
front door of the unit.
Make sure all power is removed from the system before removing
any covers.
Service Mode:
The device enters SERVICE Mode if the cabinet door is opened during Normal operation. The FILTER LEDs
blink, the unit switches off the power to the fans and stops communicating with the Fire Panel - the Laser smoke
detectors continue to communicate with the panel.
When the cabinet door is closed, the unit restarts automatically.
Filters:
Periodic cleaning or replacement of the filters is required.
The filters are located inside the cabinet at the top of the unit (see Figure 10 displayed on Page 4) and are
removed as shown in the following sequence:
Either replace the filter assembly or carefully brush off the accumulated dust.
Note: if replacing the filter, remove the foam gasket from the old
filter and place onto the new filter. When placing
the new filter into
the slot, ensure that the gasket is correctly aligned.
Refit the filter, close and secure the cabinet door. The unit will initialise and restart.
Laser Smoke Detectors:
The smoke detectors are located under the sensor cover (see Figure 10 displayed on Page 4). To access the
detectors, follow the
sequence below:
If replacing a detector, ensure that the address set on the new
detector is the same as on the detector being
replaced.
LASER SAFETY INFORMATION:
The detector contains a Class 1 laser product. Radiation emitted
inside the smoke sensor is
completely contained within its housings
and protective covers during all phases of operation.
