COPYRIGHT AS 2220.1—1989 Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage, distribution or use on network prohibited SECTION EMERGENCY WARNING SYSTEM 2.1 GENERAL The emergency warning system (EWS) shall provide a totally independent emergency warning system to alert occupants of a building to a potential emergency situation and to initiate orderly evacuation of the building, if required 2.2 SYSTEM FUNCTIONS The emergency warning system shall perform the following functions: (a) Generate alert and evacuation signals in individual evacuation zones within a building (b) Facilitate verbal address to individual evacuation zones and throughout the building (c) Indicate system status and faults (d) Operate from a dedicated battery power supply in the event of power failure Where both an emergency warning system and an emergency intercommunication system are provided, these system shall be integrated The operation of EIS shall not be inhibited when the EWS is in use The system may be used for non-emergency functions, such as paging and background music, during times of normal occupancy All non-emergency functions shall be disabled during an emergency or power failure 2.3 SYSTEM COMPONENTS The following components form parts of a system (see Appendix A for a typical block schematic): (a) Emergency control panels (ECPs) including verbal address microphone (b) Main equipment which includes amplifier and evacuation tone generators, automatic level controller, sound system power amplifiers, fault monitoring equipment, and power supply (batteries and charger) (c) Devices including loud speaker, visible alarm devices, and emergency alarm initiating devices (d) Wiring (as specified in AS 2220.2) NOTE: This Standard recognizes and is appropriate to the following system configurations: (a) A system operating from a single cabinet containing all control, signalling and amplification equipment (b) As for (a) but with a single or multiple remote ECPs (c) As for (a) and (b) but with distributed amplification equipment located in evacuation zones 2.4 EMERGENCY CONTROL PANELS (ECPs) 2.4.1 General The emergency warning system may incorporate one or more ECPs to provide a control and indication interface with the system The ECP may be co-located with the main equipment or at one or a number of strategically located control positions 2.4.2 Indicators and controls The following indicators and controls shall be provided at each ECP: (a) A key-operated AUTOMATIC/MANUAL/ ISOLATE switch as follows: (i) Automatic position In the AUTOMATIC position, the actuation of the alarm system shall activate the relevant warning system in the alert mode The key shall be removable only in the AUTOMATIC position A green light shall indicate the AUTOMATIC position NOTE: The system should remain in the AUTOMATIC position at all times unless the house warden is attending to the emergency (ii) (iii) Manual position In the MANUAL position, the automatic initiation of the emergency warning system shall be inhibited The purpose of the MANUAL position shall be to permit normal control of the warning system irrespective of the state of the alarm system and also to negate the actuation of the warning system during routine testing or maintenance of the warning system or alarm systems Any ECP shall be able to take control of the emergency warning system by turning the key switch to the MANUAL position and, once in control, it shall inhibit control of the system from other ECPs Only the master emergency control panel (MECP) key switch being placed in its MANUAL position shall override any ECP in its MANUAL position Isolate position In the ISOLATE position, the ECP shall be disabled from distributing audible and visible signals throughout the building by key panel operation All other functions shall remain operative NOTE: In this mode, the ECP may be used for training purposes without disturbing the building occupants (iv) Keys All EWIS keys shall be keyed alike with the fire indicator panel (FIP) (b) Control switches, to cause individual or simultaneous actuation of warning signal and public address announcement at selected floors or evacuation zones These controls can also be used for test periods, trial evacuation practices, etc NOTE: Different evacuation zones should be able to receive different signals simultaneously or individually, e.g Evacuation zones and 10 alert Evacuation zone public address Evacuation zone evacuate Evacuation zone public address Evacuation zones to alert (c) A microphone, to permit transmission of instructions to selected floors over the warning system This microphone may normally be that incorporated in the handset used for intercommunication (see

receiving antenna shall be located m from the transmitting antenna, aligned with the EWIS and transmitting antenna (i.e m from the EWIS) Both antennas shall be located a minimum of m away from the screened enclosure walls, or any buildings, structure or obstruction For tests between 20 and 200 MHz, where biconical antennas are used, they shall be positioned to generate alternately, vertical and horizontal fields over the test frequencies Where log spiral or helical antennas are used to generate the field, a change in the antenna is not required (b) Connect a kHz-tuned frequency selective voltmeter to a typical terminated speaker and inter-communication line Typical equipment arrangements are shown in Figures G1 and G2 G3.4 Procedure Adjust and maintain the radiated field strength at the value specified at Clause 5.3.2.7 and sweep the frequency of the signal source over the range specified, changing antennas as required Observe the EWIS and actuation devices for false operation Monitor the voltage on the speaker and inter-communication line, and measure the voltage where it exceeds the criteria at least three times per octave G3.5 Test criteria The EWIS shall not operate in an abnormal manner, change state, or generate a false actuation when subject to the test The kHz voltage measure on the speaker and communication lines shall be at least 30 dB below the voltage equivalent of maximum circuit power G3.6 Reporting of results The following information shall be reported: (a) Information identifying the equipment (b) Any false actuations (c) Measured kHz voltage

Principle The EWIS is subjected to high frequency signals injected into all conductive leads, to assess its ability to operate without false operation, under specified conditions G4.2 Apparatus The test apparatus shall consist of the following: (a) Signal source—of 50 ohm internal impedance with an output of at least IV RMS into a matched load (b) Coupling networks—to permit the injection of high frequency, common mode and differential mode, signals into the a.c power lead, actuation and communication lines The network shall have an RF impedance of not greater than ohms over the test frequency specified and shall incorporate a 50-ohm non-inductive load resistor Typical coupling networks are shown in Figure G3 (c) VTVM, oscilloscope or EMI meter—suitable for measuring the load voltage over the frequency range specified G4.3 Test preparation (a) Connect the coupling network in series with the lead appropriate to each test at a point immediately adjacent to the EWIS (b) Attach the signal source and EMI meter (or equivalent) to the coupling network (c) Connect the kHz-tuned frequency selective voltmeter to a typical terminated speaker line and inter-communication line Typical schematic arrangements for conducted susceptibility test are shown in Figures G4 and G5 G4.4 Procedure (a) Connect coupling network for differential mode operation on the a.c lead NOTE: It may not be possible to obtain an RF generator with a floating output An acceptable alternative is to connect the generator earth to the cabinet earth and then test one mains input at a time (i.e active then neutral) The signal generator wire that is not used, should be earthed via a capacitor (b) Adjust and maintain signal source level to obtain specified values across the 50-ohm load and sweep the frequency range as specified in Clause 5.3.2.7(b) COPYRIGHT Licensed to LUU MINH LUAN on 25 Feb 2002 Single user licence only Storage, distribution or use on network prohibited 33 AS 2220.1—1989 (c)
