1.1      Comply with any specific warning notices or site restrictions as identified within the site safety plan
         held by the responsible person, and with any other specific/temporary hazards identified during site
         induction/at time of visit.
1.2      All work must comply with the relevant safety procedures for working on electrical equipment.
1.3      During the inspection, the opportunity should be taken to identify dangers that might arise during
         the testing. Any location and equipment for which safety precautions may be necessary should be
         noted and the appropriate steps taken.
1.4      Before testing any system check that it is not connected to and automatic gas/water flooding
         system, any such systems are to be disconnected before testing and reconnected on completion. It
         should be noted that a Permit to Work from the Authorised Person (Boilers And Pressure Systems
         may be required, check with the Mowlem Aqumen responsible person before starting work.
1.5      Some Minerva and other smoke detectors contain a very small radio-active element and are
         not to be dismantled beyond that required to remove a detector from its’ base. The special
         precautions required for the transport and or storage and disposal of these detectors will be
         provided by the sub-contractor responsible, and approved by the MOWLEM AQUMEN
         responsible person, they must be strictly followed.
1.6      On completion of work, a final check should be made to ensure that all covers etc. to live parts have
         been securely re-fixed.
1.7      A specific ‘risk assessment’, to satisfy The Management of Health & Safety at Work Regulations
         1999, must be carried out. Due consideration to this and any other statutory regulations e.g.

         detailed below. Risk assessments are to be carried out by the operative’s employer.

2.       GENERAL REQUIREMENTS
2.1      Liase with the building manager/customer representative before starting and finishing work. If the
         fire alarm system to be tested automatically calls an outside authority, e.g., the fire brigade,
         appropriate action is to be taken to suppress such automatic action before commencing the test.
2.2      Any defects considered to adversely affect safe operation of the equipment shall be reported to
         responsible person.
2.3      Manufacturers technical literature shall, where held or obtainable, be made available to the
         operatives by the responsible person. Any instructions within the manufacturers literature that

TASK 197 (3M) INSPECT & TEST BATTERY OPERATION, ALARM & ANCILLARY FUNCTIONS INC.
TELEPHONE SWITCHBOARD FAULT INDICATORS

PROCEDURES
1. Inspect and check the fire alarm switchboard and components for damage and deterioration. Check
      the operation of the paper feed and punching mechanism whilst a functional test is carried out from the
      call point.
2. Test the earth fault indication by making a temporary connection between either L+ or L- and earth at
      any alarm call box. Under this condition the earth fault lamp on the switchboard should flash and the
      buzzer sound. Operation of the ‘Buzzer Cut Off’ key should silence the buzzer and the earth fault lamp
      should remain illuminated. Removal of the temporary connection at the alarm call box should
      extinguish the lamp.
3. Test the open-circuit fault indication by disconnecting either link L+ or L- at any alarm call box. Under
      this condition the ‘DIS’ lamp on the switchboard should flash and the buzzer sound. Operation of the
      ‘Buzzer Cut Off’ key should silence the buzzer and the ‘DIS’ lamp should remain illuminated.
      Reconnection of the link at the alarm call box should extinguish the lamp.
4. Test the short-circuit indication by making a temporary connection between L+ or L- at any alarm call
      box. Operate that call box and check that the fire call is registered, the ‘SC’ lamp on the switchboard is
      illuminated and the buzzer sounds. Operation of the ‘Buzzer Cut Off’ key should silence the buzzer
      and extinguish the lamp. Remove temporary connection at the alarm call box.
5. Test the silent test facility from an alarm call box. Open the call box; plug a portable test telephone into
      the Test jack. Operate the trip handle and check that impulses are heard in the test telephone receiver.
      Remove the test telephone plug and rewind the call point mechanism.
      Note: The silent test allows the signalling mechanism to run without sending a fire call. However the
      test is only successful if the call point is fault free.
6. Check the earth connections in each alarm call box. Clean the exposed bearings of the mechanisms in
      each alarm call box; lubricate the bearings and coat the main spring of the mechanism with light grade
      oil.
7. Where the batteries are open or accessible, a visual inspection of the battery condition, and
      connections should be made to confirm serviceability.
8. Secondary (rechargeable type) Cells
      Check that electrolyte levels and the specific gravity are correct.
9. Primary (non-rechargeable type) Cells
      Check the battery against date of installation, replace if battery life has expired or will do so before the
      next due date for this task. If the battery is not due for replacement, test it in accordance with the
      makers instructions to verify that it is suitable for continued service to the next due date for this task.
10. Check the fire alarm functions of the control and indicating equipment as follows:
     a)Operate at least one detector, call point or end of line switch on one fire “zone” of the system to test
      the ability of the control and indicating equipment to receive a signal, to sound the alarm, and operate
      any other warning devices. A different detector, call point or end of line switch within a zone should be
      tested at each occasion.
     b)Where a system has less than 13 zones, each zone is to be tested in turn.
     c)Where a system has more than 13 zones, sufficient additional zones are to be tested each week in
      turn to ensure that every zone is tested at least once every 13 weeks.
11. Check all ancillary functions of the control and indicating equipment as follows:
     a)Check in turn each fault indication by simulating that fault and noting that the appropriate indication is
      made.
     b)Visually check the control and indicating equipment for evidence of moisture ingress, mechanical or
      physical damage or other deterioration.
12. Carry out a visual inspection to confirm that there is a clear space of at least 750mm in all directions
      below every detector, and that all manual call points remain unobstructed and conspicuous.
13. If sounder operation has been inhibited during the tests, a final test - with sounders re-instated - is to be
      undertaken. This is to prove that the sounder circuits are fully operational before completing the work.

FLOODING SYSTEMS-e.g. CO2, HALON, WATER etc.

TASK 201 - (3M) INSPECT & TEST BATTERY OPERATION, ALARM & ANCILLARY FUNCTIONS

PROCEDURES
Carry out checks for 2 & 3 wire systems as described in TASK 199 and these further checks.
1 - For a Three-Wire System
Test the indicators as follows:

a)    Single indicators. At each indicating panel with single indicators press and hold the 'Test and Reset'
      button and press in turn the button under each single indicator. Each indicator lamp should light on
      operation of its associated button and the supervisory neon lamp and zone indicator lamps should
      flash at least once but not more than 60 times per minute. If this condition is not achieved the
      detector under test is suspect and should be changed.
b)    Group indicators. At each indicating panel press and hold the 'Test and Reset' button and turn each
      group selection switch from 'Off' to position 1, 2, 3 and 4. The local group indicator alarm lamp
      should light in each position to which a detector is connected. The supervisory neon lamp and the
      zone indicator lamps should flash at least once but not at more than 60 times per minute. If this
      condition is not achieved the detector under test is suspect and should be changed.
c)    Observe that the appropriate zone indicating lamps in the cabinet installed in the continuously
      manned location, flash during the above tests.
d)    Check that one detector in each circuit connected to an indicator panel operates under a simulated
      fire condition and that all indication and alarms are correctly registered. The detector is to be
      operated by using a proprietary gas tester in an aerosol canister and a different detector should be
      selected for test in rotation.
e)    Record results of the tests/checks.

2 - For a Two-Wire System
a)    Operate each 'End of Line Unit' by pressing the button on the unit. If the wiring of the circuit is sound
      the neon lamp located in the test unit will light.
b)    Check that one detector in each circuit connected to the Control Unit operates under a simulated fire
      condition and that all indications and alarms are correctly registered. The detector is to be operated
      by using a proprietary gas tester in an aerosol canister and a different detector should be selected for
      test in rotation.
c)    Record the results of the tests/checks.

3.    Where the batteries are open or accessible, a visual inspection of the battery condition, and
      connections should be made to confirm serviceability.
4.    Secondary (rechargeable type) Cells
   Check that electrolyte levels and the specific gravity are correct.
5.    Primary (non-rechargeable type) Cells
      Check the battery against date of installation, replace if battery life has expired or will do so before
      the next due date for this task. If the battery is not due for replacement, test it in accordance with the
      makers instructions to verify that it is suitable for continued service to the next due date for this task.
6.    Check the fire alarm functions of the control and indicating equipment as follows:
    a)Operate at least one detector, call point or end of line switch on one fire “zone” of the system to test
      the ability of the control and indicating equipment to receive a signal, to sound the alarm, and operate
      any other warning devices. A different detector, call point or end of line switch within a zone should
      be tested at each occasion.
    b)Where a system has less than 13 zones, each zone is to be tested in turn.
    c)Where a system has more than 13 zones, sufficient additional zones are to be tested each week in
      turn to ensure that every zone is tested at least once every 13 weeks.
7. Check all ancillary functions of the control and indicating equipment as follows:
    a)Check in turn each fault indication by simulating that fault and noting that the appropriate indication is
      made.
    b)Visually check the control and indicating equipment for evidence of moisture ingress, mechanical or
      physical damage or other deterioration.
8. Carry out a visual inspection to confirm that there is a clear space of at least 750mm in all directions
      below every detector, and that all manual call points remain unobstructed and conspicuous.
