MOUNTING:
After securing the sampling and exhaust tubes to the duct smoke unit, (or initially placing the tubes through the 1¼”
holes drilled or punched in the HVAC duct to accept the inlet sampling and exhaust tubes and then attaching them to the duct unit),
hold the duct unit assembly in position and use (2) # 12 X ½” sheet metal screws (packaged in the installation kit) to secure the
duct smoke detector to the HVAC duct.
AIR SAMPLING VERIFICATION:
To ensure correct operation of the duct unit use a Magnehelic differential pressure gauge, Dwyer
2000 or 4000 Series (or equivalent) to determine the differential pressure between the inlet (high side) and exhaust (low side)
tubes. The differential pressure between the two tubes should be greater than 0.01 inches of water and less than 1.2 inches of
water.
Note:
For proper operation, the velocity adaptor insert must be installed for air velocities of 100 to 4000 feet per minute. This
adaptor comes installed but can be removed in order to service the detector head. The adaptor must be reinstalled after the
detector head service is complete.
6. Operational Testing
When the PAD200-DUCT is under normal condition in standby mode, the alarm indicator LEDs on the detector head will pulse
approximately once every 4 seconds.
Note
: When a panel is configured to not flash LEDs, the LEDs on the detectors will not flash at any time.
7. Functional Testing
Note:
Be sure to dis-engage all alarm signal services, releasing devices and extinguishing systems, prior to performing the
following test, except automatic testing by the FACP. Be sure to re-engage these systems when all testing is complete.
8. Walk Test
The FACP must be placed into Walk Test Mode and follow the steps below. Use the appropriate steps outlined below for the
detector that is to be tested.
Notes:
•
Failure to alarm during a test indicates a defective detector. Replace detector immediately.
•
PAD200-DUCT – Use ANSI/UL listed aerosol such as Home Safeguard Model 25S and SDi Smoke Centurion as
acceptable to the Authority Having Jurisdiction (AHJ).
•
Insert the test gas nozzle into the test port on the unit cover.
9. Maintenance
The detector should be cleaned as needed. Detectors installed in environments more prone to dust may need cleaning based on
build-up of dust. Clean unit by removing cover and using soft cloth, vacuum or dry compressed air. Clean sensing tubes as needed
to allow for the free flow of air through both inlet and exhaust tubes.
Consult your local code and AHJ requirements for required maintenance schedules.
These instructions do not purport to cover all the details or variations in the equipment described, nor provide for
every possible contingency to be met in connection with installation, operation and maintenance.
