Fire Alarm Maintenance - Irish Standard 3218:2009 This requires that fire alarms receive a quarterly and annual inspection and testwhich involves that every 3 months the following checks are carried out by theservice engineer ã Entries in the log book shall be checked and any necessary action taken, ã Where applicable, batteries should be examined to ensure that the specificgravity of electrolyte in each cell is correct. ã Batteries, including reserves, shall be tested as specified by the supplier toverify that they are satisfactory for a further period. Batteries shall be replacedwithin the period of the service life stipulated by the battery manufacturer. ã The alarm functions of the control and indicating equipment shall be checkedby the operation of a detector or call point in each zone .The operation of thealarm devices and any link to an alarm receiving centre (ARC) shall be tested.All ancillary functions of the control panel shall also be tested wherepracticable. All fault indicators and their circuits shall be checked, preferablyby simulation of fault conditions. The control and indicating equipment shall bevisually inspected for signs of moisture ingress and other deterioration. ã A visual inspection shall be made to check whether structural or occupancychanges have affected the requirements for the siting of manual call points,detectors and sounders. The visual inspection shall also confirm that a clearspace of at least 500 mm is preserved in all directions below and aroundevery detector, ã that the detectors are sited correctly and that all manual call points remainunobstructed and conspicuous, ã All further checks and tests specified by the installer, supplier or manufacturershall be carried out, ã Particular attention should be made to areas where alterations to the systemhave been carried out since the last inspection.Any defect shall be recorded in the log book and reported to the responsible person,and action should be taken to correct it on the instructions of the responsible personThe following check and test sequence is carried out every year by the serviceengineer: ã each detector shall be checked for correct operation in accordance with themanufacturer’s recommendations ã every manual call point shall be checked for correct operation by insertion of atest key or operation of the switch mechanism or other test which confirms thecorrect action of the switching mechanism and ability of the device to correctlycommunicate a fire signal to the control and indicating equipment. The testshall also confirm the correct operation of any indicator device on the callpoint ã a visual inspection (as far as is reasonably practical) shall be made to confirmthat all cable fittings and equipment are secure, undamaged and adequatelyprotected, ã the required sound levels are achieved. It is strongly recommended that thisbe carried out in conjunction with the annual fire evacuation drill.Any defect shall be recorded in the log book. These shall be reported to theresponsible person for appropriate corrective actionThe operation of sounders/visual alarm indicators, detector devices shall be checkedsuch that at the end of the annual maintenance period 100 % of all devices havebeen tested.For non-residential systems of two zones or less which incorporate a combination ofless than 20 automatic detection devices or call points, then 3-monthly inspectionmay be extended to 6 months.The routine attention described in above is intended to maintain the system inoperation under normal circumstances. There may, however, be specialcircumstances in which other attention is needed: ã action by the user after any fire ã action by the user after any false alarm ã action by the user following a fault ã action by the user following a pre-alarm warning ã prolonged periods of disconnection ã other non-routine attention
