SAFETY IMPORTANT READ THIS SECTION FIRST! 1.1 Suppliers of articles for use at work are required under section 6 of the Health and Safety at Work Act 1974 to ensure as reasonably as is practical that the article will be safe and without risk to health when properly used.An article is not regarded as properly used if it is used "without regard to any relevant information or advice" relating to its use made available by the supplier. 1.
INSTALLATION - Continued 2.7 This equipment is designed to be powered from the 220 - 240V C mains supply. The mains connection must include a protective Earth conductor to the requirements of BS:7671 (see annex 2). 2.8 The mains supply must be from a separate dedicated fused spur labelled "FIRE ALARMS DO NOT SWITCH OFF". 2.
FRONT PANEL INDICATIONS - Continued 4.2 System Fault Indicator The system fault indicator will illuminate under any abnormal condition. Certain conditions may be diagnosed without looking inside the enclosure as follows:(1) System Fault on. Supply Healthy off (2) System Fault on, Zone Fault on (3) System Fault on, Zone test on (4) System Fault on, Disabled Led on (5) System Fault on. Sounder Fault on = = = = = Power failure or system fuse failure. Zone O/C or S/C in indicated zone.
INTERNAL INDICATORS 1 2 3 4 5 6 SOUNDER S/C FAULT SOUNDER O/C FAULT FUSE FAULT EARTH FAULT REM. SIG DISABLED SOUNDER DISABLED 5.1 Sounder S/C Fault Indicator This indicator will illuminate in the event of a short circuit on one of the sounder lines. 5.2 Sounder O/C Fault Indicator This indicator will illuminate in the event of a open circuit on one of the sounder lines. 5.3 Fuse Fault Indicator This indicator will illuminate in the event of :(A) Auxiliary fuse failure. (B) System fuse failure.
INTERNAL CONTROLS - Continued Four zone Sigma Normal switch positions Two zone Sigma Normal switch positions TERMINAL FUNCTIONS Smoke Detection Circuits 7.1 One to six smoke detection circuits are provided and supply 28 Volts ( + 5%) for the operation of trigger devices, (smoke detectors or heat detectors). Terminals for the smoke detection circuits are labelled Z1+ and Z1- to Z6+ and Z6- for positive and negative connections respectively.
TERMINAL FUNCTIONS - Continued Remote Alarm Input 11.1 The sounder circuits may be operated remotely via the remote alarm input. 11.2 The input is labelled (Rem AL I/P) Connection of the AUX common negative to this point will operate the sounders. This input is non latching. 11.3 The AUX Common Negative Terminal is normally pulsing at around 2 second on, 2 second off. This will pulse the Sounders at this rate if connected to the remote alarm input.

ANNEXE 3 Resistor monitoring wiring. Standard bases are used. Removal of a detector indicates fault but detectors beyond the removed one will be inoperative. Line continuity unit wiring. Diode bases are used. Removal of a detector indicates fault and detectors beyond the removed one remain operative. Connections to sounders.
