1. Installation Instructions – Introduction
This alarm is designed for installation by a qualified electrician, in accordance with
the latest I.E.E. Regulations and in regard to relevant Building Regulations.
• Read these instructions thoroughly before proceeding.
Peoples lives depend on it.
• This manual is supplied for your guidance and should not be left with the property
owner. This is for use by qualified electricians.
• AC alarms must be powered by a constant 230V AC, 50Hz supply that is not
controlled by any form of switch.
BS5839 Pt6: 1995 advises as follows:
Grade 'E' – AC only:
Connect to dedicated spur on the Consumer Unit, preferably not via a r.c.d. type
device*. (If one is deemed essential, the r.c.d. must only serve the smoke alarm
circuit. Additionally it should be independent of any r.c.d.'s protecting
sockets/portable equipment etc..)
This alarm type has no secondary power source.
* Only smoke or heat alarms must be connected on this circuit.
Grade 'D' – AC with secondary power e.g. Alkaline battery/rechargeable cells.
Connect to dedicated circuit with provisions as for Grade 'E' type or, to a regularly
used local lighting circuit, that is separately electrically protected.
• Only interconnect to the identical brand of smoke/heat or C.O. alarm. Do not
connect to any other brand of alarm/auxilary device.
• When testing the alarm, stand back so your hearing is not damaged by the 85dB
sounder.
• In new build or refurb projects, protect the alarm with a dust cap to prevent
insects or dust contamination by following trades. The property owner or other
responsible person must be advised to remove them for the alarms to operate
correctly. (Ideally, fit alarms at latest stage possible onto pre-installed
mounting base.)
• Do not Meggar Test the alarm circuit without disconnecting the alarm. Failure to
do so will cause the alarms to fail and be outside of the guarantee provisions.
Never restore power supply until all alarms are completely installed.

2. Recommended Locations for Smoke/Heat Alarms

fixture † and 300mm away from any wall.
