fire protection equipment Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage, distribution or use on network prohibited Part 10: Emergency warning and intercommunication systems in buildings SCOPE This Standard sets out requirements for the regular maintenance of the emergency warning and intercommunication system in a building (referred to as ‘system’), which complies with AS 2220.1 and AS 2220.2 REFERENCED DOCUMENTS The following documents are referred to in this Standard: AS 1259 Sound level meters 2220 Emergency warning and intercommunication systems in buildings 2220.1 Part 1: Equipment design and manufacture 2220.2 Part 2: Design, installation and commissioning SAA MP 44 Guide for the use of sound measuring equipment DEFINITIONS For the purpose of this Standard, the definitions given in AS 2220.1 and AS 2220.2, and that below apply 3.1 Owner the building owner or his agent PERIODIC INSPECTIONS 4.1 General In addition to the requirements of this Standard the system shall comply with any additional specific requirements of the Regulatory Authority The following general requirements shall apply: (a) Prior to any testing, the occupants of the building shall be advised that a test is to be conducted (b) No part or component of the system shall be disconnected, bridged or removed without the authority of the Owner and advising the House Warden (c) At the completion of the inspection, any deficiencies in the system shall be reported and shall be rectified as required in Clause 4.6 (d) The Owner shall at all times be kept informed of the current address and telephone number of the maintenance company’s service facility (e) Before performing any simulated fire alarm call, the relevant Fire Authority shall be contacted and advised of the impending test 4.2 Level maintenance routines 4.2.1 General Level maintenance routines shall consist of functional checks to ascertain that the system is operating satisfactorily and that its components are free from damage NOTE: Level routines should be carried out, or supervised, by the Owner or his representative The assistance of one or more persons may be needed to conduct these routines, but measuring instruments are not needed 4.2.2 Procedure The procedure for Level maintenance routines shall be as follows: (a) Visually check the installation that components are free from damage (b) Where the system is associated with an alarm system(s), perform a simulated alarm call, operating any one of the alarm test switches Check that an ‘alert’ alarm appears at every ECP and at the appropriate zones Check that EWIS operation is automatically initiated NOTE: A fully automatic evacuation sequence test should be carried out in conjunction with Level maintenance routines (c) Simulate an emergency condition at each control panel by setting the key switch to ‘MANUAL’, then operating function switches to each zone separately At the same time, test operation of the emergency intercommunication system (d) Check the operation of all audible and visual indicators at each ECP (e) Check that all control switches are returned to normal operating positions at the control panels (f) Check battery electrolyte level where applicable, and terminals for corrosion (g) Record the completion of tests in the logbook, noting any defects, and remedial action required The logbook shall be signed by the Owner 4.2.3 Periodicity Level maintenance routines shall be carried out not less than once every month 4.3 Level maintenance routines 4.3.1 General Level maintenance routines shall include the conduct of all Level routines, plus the necessary measurements, adjustments, repairs to ensure correct functioning of the systems NOTE: Level maintenance routines should be carried out by persons being competent and experienced in the field of emergency warning and intercommunication systems It is recommended that before carrying out these routines, the Owner be consulted in order to obtain comments (if any) on the working of the system 4.3.2 Procedure The procedure for Level maintenance routines shall be as follows: (a) Visually check the installation, location and siting of all equipment against the system installation records Record and report to the Owner any discrepancy found between the records and the actual installation (b) Check battery float charge voltage and current These shall be within specified tolerances (c) Carry out the Level maintenance routines as specified in Clause 4.2.2, steps (a) to (g), including a full automatic evacuation sequence test (d) Disconnect the a.c mains and measure the standby battery voltage under full load conditions The battery voltage shall not be less than 95 percent of the nominal voltage If less than 95 percent of the nominal voltage, the battery shall be tested (see Clause 4.4) COPYRIGHT AS 1851.10—1989 (e) Reconnect the a.c mains and measure the current from the battery charger This current shall be within specified tolerances (f) Check operation of all mechanical and electrical components of the system (g) Measure the audible signal level and compare it with the level achieved at the previous inspection Consult the Owner regarding any changes in ambient noise levels that may have occurred since the previous inspection Make adjustments as necessary to comply with AS 2220.2 Licensed to LUU

from the system and replace it with a temporary battery of the same or greater capacity (b) Discharge the system battery at a current of: Idis where Idis Iq Ifl = = the discharge current = the system’s quiescent current = the full load current of the system (c) The time taken for the battery to reach the discharged terminal voltage (as specified in the log book) shall be recorded in the log book and is to be greater than 90 mins (d) The system battery is to be charged to a capacity greater than 95% before being reconnected to the system and the temporary batteries removed NOTE: If required the system battery can be removed from the building to another location to have the capacity test performed 4.5 Reporting and recording 4.5.1 General All results of Level 1, Level maintenance routines and battery tests shall be reported in writing to the Owner and be permanently recorded in accordance with the requirements of Clauses 4.5.2 and 4.5.3 4.5.2 Logbook The logbook shall comply
