1.0
Purpose
This document provides a procedure for conducting periodic testing of a fire-detection device required by NFPA 72 National Fire Alarm Code, 2010 Edition Table 14.4.2.2 Device 14(f) and Table 14.4.5 Component 15(g).
2.0
Scope
This test is to be performed annually on fenwal analaser aspiring smoke detection.
3.0 Planning
3.1 Notify the facility work coordinator using the approved electronic work control notification procedure. Allow one week for approval of the requested work and be prepared to reschedule the requested work to satisfy the areas production schedule.
3.2 Staff Required: 2
3.3 Time Required: 0.5 Hours
3.4 Equipment Required
· Manufacturer’s Manual (See ‘References’ section below.)
· Safe Guard Aerosol Smoke Tester
· Stop Watch
· Magnehelic Gauge (differential pressure measuring device)
4.0
Test Preparation
4.1
Establish the fire-detection system
impairment using the Fire
Protection Supplemental Chapter 5: Fire Protection System Impairment Procedure
for detailed instructions on work planning, advanced notification, and
administrative controls.
· Post the ‘Fire Alarm
Systems Testing in Progress’ notification signs.
4.2
Invite
the SOTR to witness the test.
4.3
Evacuate
hazard area of unnecessary personnel.
4.4
Station
a knowledgeable technician at the Fire Alarm Control Panel (FACP); disconnect
the building audible alarms at the FACP.
The knowledgeable technician is to remain attentive at the FACP at all
times that the audible alarms are disconnected.
· In the unlikely event that an unanticipated
fire alarm signal is received on the FACP, the technician must 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 attached datasheet.
5.2
Visually inspect the entire piping network,
including hangers or supports. Check for
mechanical damage or abnormalities.
5.3
Check the condition of the control panel batteries
and charging circuit.
5.4
Perform the Gross Smoke Test.
5.4.1
Introduce aerosol smoke into the last sampling port of each branch.
5.4.2
Measure the elapsed time required for the respective display bar graph to illuminate
10 bar-graph segments.
5.4.3
Record
the
time on the attached data sheet.
5.4.4
Verify alarm conditions are indicated at the:
· associated agent
release panel;
· building FACP;
· Fire Protection Engineer’s pager.
5.4.5
Place
a "Tested" sticker on the detector housing with date and
technician’s name.
5.5
Perform
the Sampling Hole
Air-Flow Verification Test.
5.5.1
Measure
the suction pressure of the first and
last sampling hole.
5.5.2
Record
the suction pressure data on the attached
data sheet.
5.6
Perform
the Detector Sensitivity Test.
5.6.1
Depress
the TEST BUTTON on the front of the display control
card.
5.6.2
Verify
the detector returns a signal that will cause a 70% to 90% deflection
on the display control card. Record the steady state smoke level displayed
on the attached data sheet.
6.0
System Restoration
6.1
Reconnect
the building audible alarms at
the Fire Alarm Control Panel.
6.2
Dismiss
assisting technician at the FACP.
6.3
Remove
the ‘Fire Alarm Systems Testing in Progress’ notification signs previously
posted.
6.4
Notify
the SOTR when the tests are complete and the system is on-line and
operational. Allow SOTR to verify that
the system is in normal operating condition.
6.5
Allow
personnel to return to the area previously designated as hazardous.
7.0
Conclusion
Upon
completion of the procedure, fenwal analaser aspiring smoke detection is on-line
and operational.
