Figure 14. Testing detector alarm:
Trouble — If the detector LED does not flash, then the detector lacks power (check wiring, panel, or power supply), the detector board is miss- ing (replace), the cover has been missing or not secured properly for more than 7 minutes (secure cover properly), or the unit is defective (return for repair).
Test — The trouble condition can be caused intentionally to verify correct operation of the system. Remove the detector board to cause a trouble condition locally and at the system control panel.
Cover
Tamper — If the cover is removed or not properly secured for a period longer than 7 minutes, a trouble signal is generated to indicate the cover is missing.
[6.2.2] Alarm Tests
[6.2.2.1]
1.Place the painted surface of the magnet onto the TEST locator on the bottom of the housing (Figure 14).
2.The red alarm LED 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 system control panel, front cover reset button, or remote accessory.
[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 detec- tor as indicated in the RTS451/RTS451KEY manual. The DH100ACDCLP 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 10; wire runs must be limited to 25 ohms or less per interconnecting wire.

NOTE: Wiring diagram shown is for DH100ACDCLP
Please note that the magnetic coil supplied with the RTS451 and RTS451KEY is not required when these accessories are used with the DH100 Series detectors. The functionality of the magnetic coil has been designed into the circuitry of the new Innovair™ duct smoke detectors.
[6.2.2.3] SSK451
The System Sensor SSK451
To install the SSK451, connect the device as shown in Figure 13.
[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.
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 chamber 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 Board
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
