[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 13).
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 detector as indicated in the
RTS451/RTS451KEY manual. The DH100ACDCLWP duct smoke
detector can be reset by the RTS451/RTS451KEY. If a system con-
trol 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 inter-
connecting wire.
Please note that the magnetic coil supplied with the RTS451 and
RTS451KEY is not required when these accessories are used
with the DH100ACDCLWP detectors. The functionality of the
magnetic coil has been designed into the circuitry of the new In-
novair™ duct smoke detectors.
[6.2.2.3] SSK451 Multi-Signaling Accessory
The System Sensor SSK451 Multi-Signaling accessory combines
a sounder feature with a key activated test and reset function.
Green, amber and red LEDs provide a visual indication of power,
trouble, and alarm respectively. An optional strobe (PS24LO)
with a smoke lens can be added to conform to the codes of cer-
tain jurisdictions.
To install the SSK451, connect the device as shown in
Figure 12.
[6.2.3] Sensitivity Tests
[6.2.3.1] MOD400 or MOD400R Test
After verification of alarm capability, use the MOD400R test mod-
ule 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 detec-
tor, the detector chamber requires cleaning per Section [7] of
this manual.
Using flexible tubing and rubber stoppers, connect the HIGH side
of the transmitter to the sampling tube of the duct smoke detector
housing, and the LOW side of the transmitter to the exhaust tube
of the duct smoke detector housing. Measure and record the volt-
age drop across the 1000 Ω resistor (measurement 2). Subtract the
voltage recorded in measurement 1 from the voltage recorded in
measurement 2. If the difference is greater than 0.15 volts, there
is enough air flow through the duct smoke detector for proper
operation. Once readings are complete, reinsert both filters and
reinstall cover. Reconnect power.

[6.1.5] Filter Replacement
The filters do not substantially affect smoke performance even
when up to 90% of the filter is clogged. Quarterly visual inspec-
tion usually suffices to determine whether the filters should be
replaced because only a high percentage of contamination affects
performance. If further testing is required, compare differential
pressure readings with and without the filters installed. If the
difference exceeds 10% replace the filters. In no case should the
pressure differential fall below 0.0015 inches of water.
[6.2] Standby, Alarm and Sensitivity Tests
The cover must be removed to perform these tests. The use of
a remote accessory for visible indication of power and alarm
is recommended.
[6.2.1] Standby And Trouble
Standby— Look for the presence of the flashing green
LED. The LED should flash approximately ev-
ery 10 seconds.
Trouble— If the detector LED does not flash, then the
detector lacks power (check wiring, panel, or
power supply), the detector board is missing
(replace), the cover has been missing or not se-
cured 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 sig-
nal is generated to indicate the cover is missing.
