[10.1] poweR the Unit
Apply 12VDC or 24 VDC to terminals marked as (+) and (–)IN, see Figure 6,
and electrical specs for details.
[10.2] peRfoRM DetectoR check
VERIFY STANDBY per Section 9 on page 4. The use of a remote accessory is
recommended.
10.2.1 coVeR taMpeR
Removal of the cover on the sensor side of the housing will result in a trouble
condition. The unit with cover removed will remain powered while any units
between this unit and the eol resistor will loose power.

Maintenance pRoceDUReS
Test and maintain duct smoke detectors in accordance with local regulations
and codes of practice. The tests contained in this manual were devised to as-
sist maintenance personnel in verification of proper detector operation.
Before conducting these tests, notify the proper authorities that the smoke
detection system will be temporarily out of service. Disable the zone or system
under test to prevent unwanted alarms.

[10.4.1] SMoke entRy USing aeRoSoL SMoke
This test is intended for low-flow systems <2.54 m/sec. If the air speed is
greater than 2.54 m/sec, use a conventional manometer to measure differen-
tial pressure between the sampling tubes, as described in 7.1.
Drill a .63 cm hole 91.4 cm upstream from the duct smoke detector. With the
air handler on, measure the air velocity with an anemometer. Air speed must
be at least 1.5 m/sec. Spray aerosol smoke into the duct through the .63 cm
hole for five seconds. Wait two minutes for the duct smoke detector to alarm.
If the duct smoke detector alarms, air is flowing through the detector. Remove
the duct smoke detector cover and blow out the residual aerosol smoke from
the chamber and reset the duct smoke detector. Use duct tape to seal the aero-
sol smoke entry hole.
CAUTION
Canned aerosol simulated smoke (canned smoke agent) formulas will vary
by manufacturer. Misuse or overuse to these products may have long term
adverse effects on the smoke detector. Consult the canned smoke agent man-
ufacturer’s published instructions for any further warnings or caution state-
ments.
[10.5] inStaLL the coVeR
Install the covers making sure that the cover fits into the base groove. Tighten
the seven screws that are captured in the covers.
NOTE: Verify sensor cover gasket is properly seated on cover prior to cover
installation
[11] DetectoR cLeaning pRoceDUReS
Notify the proper authorities that the smoke detector system 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.
[11.1] DetectoR SenSoR
1.
Remove the sensor to be cleaned from the system.
2.
Refer to the relevant detector installation manual for cleaning instructions.
3.
Re-install the detector
[11.2] ReinStaLLation
1.
Reinstall the detector in its housing.
2.
Restore system power.
3.
Perform Detector Check, Section [10.2].
4.
Notify the proper authorities testing has been completed and the smoke
detector system is back in operation.
[12] SenSoR RepLaceMent
1.
Remove the sensor head by rotating counterclockwise.
2.
Pull gently to remove it.
3.
To replace the sensor head, align the mounting features and rotate clock-
wise into place.
