Test Preparation
4.1
Establish
the fire-detection system impairment using Chapter 5: Fire Protection System Impairment Procedure
for detailed instructions on work planning, advanced notification, and
administrative controls.
4.2
Post
the Fire
Alarm Systems Testing in Progress sign(s).
4.3
Invite
the technical representative (TR) to witness the test.
4.4
Evacuate
the hazard area of all personnel.
4.5
Station
a knowledgeable technician at the Fire Alarm Control Panel (FACP).
4.6
Disconnect
the building audible alarms at the FACP.
4.7
The
technician is to remain attentive at all times that the audible alarms are disconnected.
4.8
In
the unlikely event an unanticipated fire alarm signal is received on the FACP,
the technician shall reconnect the building audible devices and join the
building evacuation.
5.0
Conduct the Test
5.1
Record
the detector’s serial number and location on the Duct Smoke
Detector Data Sheet.
5.2
Using
the List Sensitivity menu, check the sensitivity of each detector.
5.3
Refer
to the Device Analog Voltage Table for a list of acceptable detector
sensitivity ranges.
5.4
If
the Partial System Disable LED is lit, use the Control Arm/Dis menu to check
that all appropriate detectors are
armed.
5.5
Activate
the detectors using the Fumax cartridge and record response time.
5.6
Verify
alarm conditions are indicated in the following locations:
·
detector
LED;
·
building
FACP;
·
alarm
viewer and associated graphic display; and, the
·
Fire
Marshal’s pager
5.7
Verify
that the alarms can be acknowledged and that the system can be silenced and
reset.
5.8
Using
the Magnehelic Gauge, test the air sampling tube differential pressure. Record
the measured differential pressure on the Data Sheet.
5.9
Remove
the detector head from the duct housing, and clear all passages of the detector
head using the Air Blast Cleaner.
5.10
Return
the detector head to its base in the duct housing and verify proper sample-hole
orientation.
5.11
Check
for air leaks.
5.12
Document
results on the Duct Smoke
Detector Data Sheet
6.0
System Restoration
6.1
Reconnect
the building audible alarms at the FACP.
6.2
Dismiss
the assisting technician at the FACP.
6.3
Remove
the Fire
Alarm Systems Testing in Progress notification signs previously posted.
6.4
Notify
the TR that the tests are complete and the system is on-line and
operational.
6.5
Allow
the TR to verify that the system is in normal operating condition.
6.6
Allow
personnel to return to the area previously designated as hazardous.
7.0
Conclusion
Upon completion of the procedure,
the Duct Smoke Detector is on-line and operational.
