A range of reliable, hard wired Carbon Monoxide alarms with battery backup. They are designed for use in all domestic and light commercial environments.

Every unit in the SF340 series utilises the advanced ECO-Sure electrochemical cell sensing technology and comes complete with a full 10 year guarantee on the main unit and a full 5 year guarantee on each sensor module.

Every unit in the SF340 series offers up to 5 years battery backup allowing for continuous protection – even in the event of power loss. This also allows the unit to be operational whilst waiting for permanent installation.

Units can be provided to operate from various voltage options. 230Vac or 12/24Vdc units are all available for differing applications.

The SF340 has been specially designed for permanent, secure installation and is ideal for use by local authorities, housing associations and any organisation responsible for the safety of tenants and the maintenance of their homes.

The SF340 series of alarms incorporate a unique module replacement system. There are no re-wiring or main unit replacement costs, just a simple, clip-in module to change once every 5 years. This results in low ownership costs and minimal maintenance. Locking screws also ensure that only authorised persons can gain access to the unit.

Units are available with relay output and interconnect options. This enables connection to control panels, shut-off valves, remote alarms... etc, as well as allowing numbers of alarms to be linked together in series.

An internal diagnostic facility means the SF340 carries out continuous self-monitoring. If any fault is located in the sensor, battery or circuits, the unit will automatically give a warning signal within 60 seconds.
