The SF340 Series is a range of reliable, hard-wired Carbon Monoxide alarms with battery back-up. They are designed for use in all domestic and light commercial environments
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.
