Procedure for Testing

Clean Agent Suppression System Control Panels




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( 2).


2.0             Scope


This test is to be performed semi- annually on each clean agent suppression system control panel.


3.0             Planning


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.


3.1.            Staff Required: 2

3.2.            Time Required: 2 Hours

3.3.            Equipment Required:

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

·         Safe Guard Aerosol Smoke Tester

·         Air Blast Aerosol Cleaner

·         Thermometer or Temperature Gauge

·         Clean Agent Control Panel Data Sheet

·         Cylinder Inspection Data Sheet


4.0             Test Preparation


4.1.            Ensure access to the necessary equipment is available and does not interfere with accelerator operation.

4.2.            Reference 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.

4.3.            Notify the SOTR to witness the test.

4.4.            Evacuate hazard area of all personnel.

4.5.            Disconnect the building audible alarms at the Fire Alarm Control Panel (FACP); station a knowledgeable technician at the FACP at all times the audible alarms are disconnected. The knowledgeable technician is to remain attentive, at the FACP, until the audible alarms are reconnected.

·         In the unlikely event an unanticipated fire alarm signal is received on the FACP, the technician must reconnect the building audible devices and join the building evacuation.

4.6.            Disconnect clean agent system control and releasing devices from agent storage cylinders and tag out.


5.0             Implementation


5.1.            Clear all passages on smoke detectors with Air Blast Aerosol Cleaner.

5.2.            Record all agent storage cylinder serial numbers, Tare/Gross/Net weight, hydrostatic test date, pressure and ambient temperature. Note any mechanical damage to the storage cylinders or cylinder brackets.

5.3.            Record discharge nozzle and orifice plate nomenclature, and verify that no obstructions exist.

5.4.            Examine the entire piping system, including hangers, and verify that everything is secure.

5.5.            Note any signs of corrosion on the piping system or abrasion on flexible discharge hoses.

5.6.            Verify that all instruction and warning plates are installed properly and are legible.

5.7.            Using the Safe Guard aerosol smoke tester, verify the operation of each smoke detector.

5.8.            Use the Air Blast aerosol cleaner to clear passages after smoking each detector.

5.9.            Operate all manual actuation and abort controls and reset after verification of proper operation.

5.10.        Verify the operation of the releasing mechanism, and record data indicating zoning, notification appliance operation and pre-discharge delay setting.

5.11.        Record backup battery condition and verify charging circuit.

5.11.1.  Verify that the detector LED lights.

·      Verify proper indication of the suppression control panel.

·      Verify an alarm condition is indicated on the NCC workstation. workstation at security post 2, alarm viewer and associated graphic display.

·      Verify an alarm condition is indicated on the Fire Marshal’s pager.


6.0             System Restoration


6.1.            Reconnect clean agent control and releasing devices, and remove lock out tag out.

6.2.            Reconnect the building audible alarms at the suppression control panel.

6.3.            Dismiss assisting technician at the FACP.

6.4.            Remove the ‘Fire Alarm Systems Testing in Progress’ notification signs previously posted.

6.4.1.      Notify the SOTR when the tests are complete and the system is on-line and operational.  Allow SOTR to verify normal operating conditions of the system.

6.4.2.      Allow personnel to return to the area previously designated as hazardous.


7.0             Conclusion


Upon completion of the procedure, the clean agent suppression system control panel is on-line and operational.
