MADE IN UK
The Thorn Security MF601M (516-050-401) is an ionisation smoke detector for a shipboard fire alarm system, and this unit comes together with its base. Placed in a protected space, it uses an ionisation chamber to detect smoke and signals the fire alarm control panel when smoke is present, giving the crew early warning of a fire. The chamber contains an americium-241 source below 0.9 µCi. Made in the UK, the detector and base are offered in New Without Box condition for ships that keep this detector series in service.
