Appendix 6:

Procedure for Testing

Protectowire Heat Detector




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, 2019 Edition Table Device 17(4),(b).


2.0             Scope


This test will be performed ANNUALLY on each protectowire heat detector.


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: quantity dependant

3.4              Equipment Required:

·               Manufacturer’s Manual (see ‘References’ section below)

·               Small Piece of Bare Copper Wire

·               Protectowire Heat Detector 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              Test the protectowire heat detector by introducing a small piece of bare copper wire across the "end of line resistor" located at the EOL junction box for each zone.

5.3              Observe operational condition of each heat detector.

5.4              Check each detector for paint or obstruction.

5.5              Verify alarm conditions are indicated at the following locations:

·         associated agent release panel

·         building FACP

·         workstation at security post 2, alarm viewer and associated graphic display

·         Fire Marshal’s pager

5.6              Document results on attached data sheet.

5.7              Place a "Tested" sticker on the detector housing with date and technician’s name.


6.0             System Restoration


6.1              Reconnect the building audible alarms at the FACP.

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 that the tests are complete and 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, the protectowire heat detector is on-line and operational.
