System Sensor INNOVAIR DH100LP - Manual (Page 7)

Test — The trouble condition can be caused inten-
tionally to verify correct operation of the sys-
tem. Remove the detector board to cause a
trouble condition locally and at the system
control panel.
[6.2.2] Alarm Tests
[6.2.2.1] M02-04-00 Magnet Test
1. Place the painted surface of the magnet onto the TEST
locator on the bottom of the housing (Figure 9).
2. The red alarm LEDs on the detector should latch on,
as should any accessories (i.e. RA400Z, RTS451). 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 must be reset by the system control panel,
the local reset button, or the remote accessory.
Figure 10. Testing detector alarm:
[6.2.2.2] RTS451/RTS451KEY Remote Test Station
The RTS451/RTS451KEY Remote Test Station facilitates
test of the alarm capability of the duct smoke detector as
indicated in the RTS451/RTS451KEY manual. The DH100LP
duct smoke detector can be reset by the RTS451/RTS451KEY.
If a system control panel is used, the panel itself may also
require testing.
To install the RTS451/RTS451KEY, connect the device as
shown in Figure 9; wire runs must be limited to 25 ohms
or less per interconnecting wire.
[6.2.3] Sensitivity Tests
[6.2.3.1] MOD400 or MOD400R Test
After verification of alarm capability, use the MOD400R test
module with a voltmeter to check detector sensitivity as
indicated in the test module’s manual. The housing cover
must be removed to perform this test.
D200-15-00 7 I56-0083-07R
If test module readings indicate that the detector head is
outside of the acceptable range that is printed on the label
of the detector, the detector requires cleaning per Section
[7] of this manual.
[7] Detector Cleaning Procedures
Notify the proper authorities that the smoke detector sys-
tem is undergoing maintenance, and that the system will
temporarily be out of service. Disable the zone or system
undergoing maintenance to prevent unwanted alarms and
possible dispatch of the fire department.
[7.1] 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. If they are not heavily coated, use a vacuum
cleaner or compressed air nozzle to remove dust, then
reinstall the filters.
[7.2] 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 (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.
[8.0] Board Replacement
[8.1] Detector Board Replacement (part no. A5180)
1. Remove the two detector board mounting screws.
2. Pull gently on the board to remove it.
3. To replace the board, align the board mounting features,
holes, and the interconnect terminals. Push the board
into place.
4. Secure board with the two mounting screws.
[8.2] Power Board replacement (part no. A5061)
1. Disconnect wiring from the terminal block.
2. Remove the two power board mounting screws.
3. Pull gently on the board to remove it.
4. To replace the board, align the board mounting features,
holes, and the interconnect terminals. Push the board
into place.
5. Secure board with the two mounting screws.
6. Re-connect wiring to terminal block.
