Magnet Test:
Testing can be accomplished with the cover installed or removed. Place the magnet (Part #0700-01117 or
suitable bar magnet) on the detector as shown in Figure 4 / Figure 5 for approximately six (6) seconds to
activate the alarm LEDs and relays. This test will verify that the detector is within its intended limits.
Model FCD-350 Automatic Verfication:
The detector has a built-in sensitivity window verification feature. If the detector is within its calibrated
sensitivity range the detector LEDs will flash Green in standby or normal operation. If the detector drifts
outside its sensitivity range the LEDs will flash Red to indicate an out of sensitivity condition.
Smoke Test Port:
The FCD-350 has a smoke port for the introduction of smoke or simulated smoke without cover removal
by lifting the port tab. To test with aerosol smoke, use a
1
2
inch diameter pipe (or equivalent) at the
manufacturer's recommended minimum length to introduce the aerosol into the port. Press the pipe against
the detector housing and spray from the opposite pipe end, pipe elbows can be used. The amount of
aerosol is dependent on the duct air velocity, see below for estimated activations:
1,000-2,000 FPM: 3 seconds, 1 activation
2,000-3,000 FPM: 4 seconds, 1 activation
3,000-4,000 FPM: 4 seconds, 2 activations
The port must be closed after testing to avoid air leakage from the duct.
Test Switch:
Pressing the test switch will test the alarm relays, it will not test the detector's sensing element. The switch
must be pressed to reset the detector after an alarm activation.
