Stand Alone Fire Alarms

Battery Operated

A comprehensive range of battery operated smoke alarms all carrying the BS Kitemark and compliance with BS5446:Pt1:1990. They are suitable for BS5839:Pt6:1995 Fire Systems grade F.

Mains Powered Interconnectable

All new properties are required by the Building Regulations to have installed mains powered smoke alarms. Refurbished properties and small commercial premises may also be required to install mains operated alarms.
BS5839:Pt.6:1995 acknowledges that all three types of detection i.e. ionisation, optical and heat detection, need to be considered depending on the installation circumstances. It is also recommended that some form of back-up is used in the event of mains failure.
Optical alarms are recommended for use in circulation spaces such as landings and hallways. Ionisation alarms are more appropriate for use in living rooms and fixed temperature heat alarms are designed for use in kitchens and garages. All alarms must be interconnected using 3 core and earth cable.

At least one alarm on each floor of the house
Max. 7.5m between alarms and no more than 3m from bedroom doors
Alarms can be wired off lighting circuits if the alarm has its own backup supply
Locate as close as possible to centre of ceiling, away from light fitting
Alarms must be kept clean at all times and particularly whilst building work or decoration is in progress

Mains Operated

Suitable for new buildings to allow conformity to building regulations. Each unit features an 85dB at 3m internal alarm and interconection facility which allow the sensing unit to trigger up to 11 other detectors, for added safety and particularly when one unit might not be heard in a large building or from behind closed doors.
The unit causing the alarm also has an indicator to show the source. Each unit has a green continuous LED to indicate mains present.
These products can also be fitted using the surface mounting kits. A relay output option is also available to allow for triggering of remote indicators or other communication/alarm systems. All units are supplied complete with instructions.
290-3816 = 12V Operating Voltage with Relay Output.
