To verify the air pressure differential
To verify air pressure differential, air must be moving
through the HVAC system.
Connect a suitable air pressure differential
meter model Reed R3001 or equivalent to the
sampling tube and exhaust tube openings as shown
in Figure 13.
Figure 13 Air Pressure measure
13.
Verify that the air pressure differential
measured falls within the specified
operating range of the detector.
Model
Air pressure
FW562C-A
0.36 to 1.53 iwg (inches of water)
90 to 380 Pa (Pascals)
FW562C-B
0.04 to 0.4 iwg (inches of water)
9 to 100 Pa (Pascals)
FW562C-C
0.004 to 0.06 iwg (inches of water)
1 to 15 Pa (Pascals)
FW562-A
0.32 to 1.41 iwg (inches of water)
80 to 350 Pa (Pascals)
FW562-B
0.1 to 0.4 iwg (inches of water)
25 to 100 Pa (Pascals)
FW562-C
0.004 to 0.14 iwg (inches of water)
1 to 35 Pa (Pascals)
14.
If the air pressure differential measured
does not fall within the specified operating
range of the detector, make sure the
sampling tube air holes are not obstructed
and are facing the HVAC system airflow.
15.
After completing the installation of the duct
smoke detector, test the detector to ensure it is
operating correctly.
Main function
Models FW562-A/B/C and FW562C-A/B/C Duct
Smoke Detectors utilize photoelectric smoke
detectors for the detection of smoke. When
sufficient smoke is sensed, an alarm signal is
initiated.
Test function
⚫
Alarm simulation: Pressing the TEST SW can
simulate an alarm condition.
⚫
Cover tightness monitor: When the JUMPER
switch is on the NORMAL side, a trouble event
will be annunciated when the cover is not
secured properly. When the JUMPER switch is
on the TEST side, this feature will be bypassed.
Note the TEST mode should only be used in
installation and field testing.
To clean the duct smoke detector
1.
Disable the detector/zone to prevent false
alarms.
2.
Remove the detector
’
s cover then power down
the detector by disconnecting the SLC wiring.
3.
Using a vacuum cleaner, or clean compressed air,
with a soft bristle brush, remove loose dirt and
debris from inside the detector housing and
cover.
4.
Remove dirt and other contaminants from the
gasket on the detector
’
s cover using isopropyl
alcohol and a lint-free cloth.
5.
Squeeze the retainer clips on both sides of the
optic housing then lift the housing away from
the printed circuit board.
6.
Gently remove dirt and debris from around the
optic plate and inside the optic housing.
7.
Replace the optic housing and detector cover,
and then connect the SLC wiring.
Return the product for reparation if it fails to flash or
alarm during testing. Do not disassemble the
product without permission.
