Procedure for Testing

Fenwal Analaser Aspiring Smoke Detection




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 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)

·       Fenwal Analaser Data Sheet


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.
