General
The KL731 is a conventional optical detector of outstanding performance, efficiency and durability.

The 700 series fire detectors are the ideal solution for conventional installations. They are designed specifically for use with the Kilsen NKB600 and NK700 series conventional fire panels, but are also compatible with most 3rd party industry standard conventional control panels.

A fire detector for every need
With an attractive design and advanced features, these fire detectors have been specifically designed to cope with difficult and even extreme situations. The series comprises a range of detectors including ionisation, optical and heat detectors, with a universal base that suits every application and even compensates for uneven surfaces. All bases are provided with an integral locking mechanism for extra security, and all sensors support the connection of a remote indicator.

KL731 Photoelectric Smoke Sensor These detectors use the Tyndall effect of smoke in the chamber to detect a fire. It can detect a smouldering fire (without flames). They are normally used in areas where possible fires generate visible smoke, like plastics, polystyrene, PVC, etc. The KL731 boasts a field exchangeable optical chamber. A simple recalibration using the KCT731 returns the maintained detector to normal operating conditions as if it was brand new.
