ENVIRONMENTAL PROTECTION
Waste electrical products should not be disposed of with household waste. Please recycle where facilities exist. Check with your Local Authority or retailer for recycling advice.
Application
- This surface mount relay pattress is for use with Kidde Fyrnetics & Firex, Hard Wired Smoke & Heat alams, where surface cabling is being used, such as in retrofit applications. It can be used, via a suitable relay control, to trigger auxiliary devices such as door closers, warning lights, horns, Warden call systems etc.
Usage
- This is designed for installation by a qualified electrician, in accordance with the current IEE regulations. Failure to install correctly can result in a fatal shock or fire hazard.
- Alarms must be connected direct to the Consumer Unit on a separate circuit – see current Wiring Regulations.
- Knock-outs on the underside and edge of the pattress provide flexibility of cable entry, for ease of use. A small rib on the edge of the pattress lines up with a mark on the alarms base plate, to ensure correct alignment.
- Site and select alarm type in accordance with manufacturer literature/manual shipped with alarm. Also refer to Building Regulation requirements if applicable, plus BS5839 Pt 6.
- Isolate mains power before commencing work.
- Never remove/refit the cable harness whilst mains power is present.
- Crossing line and neutral connections or line and interconnect connections will fatally damage all interconnected alarms invalidating the guarantee.
- Never Meggar Test an installation, without disconnecting any connected alarms (this can permanently damage the alarm and invalidates the guarantee).
All interconnected alarms must be powered off the same fuse/circuit breaker.
Total cable length between alarms must not exceed 250m (273yds) and be 1.5mm
in diameter, 3 core and earth (BS6243Y).
The apparatus shall not be exposed to dripping or splashing.
An all pole mains switch with a contact separation of at least 3mm in each
pole shall be incorporated in the electrical installation of the building.
This apparatus should be connected to the mains with a protective earthing
connection.
The intended condition of use prevents this apparatus from being accessed by
children.
Important Notes
- Up to 23 Mains powered Kidde Fyrnetics & Firex Smoke or Heat interconnectable alarms may be wired into this relay unit.
- Any devices hung off this relay must not give an alarm state until relay contacts have been activated for at least 200 milli-seconds.
- All alarms with secondary power back-up continue to function, even if there is loss of mains power, but this relay will not be able to function – it requires a healthy 230V supply.
- By default, this relay will not reset until alarm ceases to sense smoke/heat that has caused the alarm to trigger.
- As in illustration 1, bring mains cabling into pattress terminal block via knock-out selected and fix pattress to ceiling with 2 screws. (If using dry lining box, select appropriate holes on pattress and secure with machine screws.)
- Connect flying leads on alarm cable harness to appropriate terminals and ensure polarity is correct.
- Install and test alarm by following guidance in Installer Manual of alarm.
- Interconnect only – if single alarm installation, leave unconnected with sheathing intact.
These are double insulated products and do not need earthing – never use earth conductor to interconnect – use 3 core and earth (BS6243Y).
Connect to Terminal Block in ceiling cavity or via Surface Pattress.
This accessory is also suitable for use with Kidde Slick® alarms.
- Interconnect only – if single alarm installation, leave unconnected with sheathing intact.
These are double insulated products and do not need earthing – never use earth conductor to interconnect – use 3 core and earth (BS6243Y).
Connect to Terminal Block in ceiling cavity or via Surface Pattress.
This accessory is also suitable for use with Firex alarms.
