[9.2.2] Alarm Tests
[9.2.2.1] M02-04-00 Magnet Test
1. Place the painted surface of the magnet onto the TEST locator
on the bottom of the detector housing (Figure 12).
2. Verify system control panel alarm status and control panel execution of
all intended auxiliary functions (i.e. fan shutdown, damper control, etc.)
3. The detector is self-restoring when the magnet is removed.
Verify that the system control panel has reset.
[9.2.2.2] RTS451/RTS451KEY Remote Station Test
The RTS451/RTS451KEY Remote Test Station facilitates test of the alarm
capability of the duct smoke detector. These accessories provide the
stimulus to initiate an alarm condition at the detector. The detector is
self-restoring when the accessory test stimulus is removed.
Verify that the system control panel has reset.
[9.2.3] Sensitivity Tests
Notify the proper authorities that the smoke detector system is undergoing maintenance, and that the system will temporarily be out of service. Disable
the device or system undergoing maintenance to prevent unwanted alarms and possible dispatch of the fire department.
[9.3] Maintenance of Duct Smoke Detectors
[9.3.1] Air Filters
1. Turn off power to the system.
2. Remove and inspect sampling tube filters.
3. If filters are heavily coated with dirt, replace them with new filters (p/n F36-09-11). If they are not heavily coated,
use a vacuum cleaner or compressed air nozzle to remove dust, then reinstall the filters.
[9.3.2] Photo Detector Boards
1. Remove the screen by gently grasping on each side and pulling straight off
2. Lift the photo chamber in the same fashion. Vacuum the screen and cover. Use clean, compressed air to loosen and
blow out any remaining debris. Replacement screens (p/n S08-39-01) are available.
3. Vacuum photo chamber, then use clean compressed air to blow area clean.
4. Replace the chamber by pressing it onto the base. Press the screen into place. It should fit tightly on the chamber.
