[6.2.1] Standby And Trouble

Standby — Look for the presence of the flashing green LED. The

LED should flash approximately every 10 seconds.

Trouble — If the detector LED does not flash, then the detec-

tor lacks power (check wiring, panel, or power
supply), the detector board is missing (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] 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  detec-
tor  as  indicated  in  the  RTS451/RTS451KEY  manual.  The
DH100ACDCLPX 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.

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 detec-
tors.

[6.2.2.3] SSK451 Multi-Signaling Accessory

The  System  Sensor  SSK451  Multi-Signaling  accessory  com-
bines  a  sounder  feature  with  a  key  activated  test  and  reset
function. Green, amber and red LEDs provide a visual indica-
tion  of  power,  trouble,  and  alarm  respectively.  An  optional
strobe (PS24LO) with a smoke lens can be added to conform
to  the  codes  of  certain  jurisdictions.  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.
