An infra-red detector 3, intended particularly for use in a smoke detector 5, adapted to be triggered by any conventional infra-red remote control. Allows a ceiling mounted smoke detector to be readily switched off when triggered by a non-serious incident. The detector may be fitted to new alarms or retrofitted to existing devices. The infra-red detector is only powered up and triggerable when smoke detector's alarm is active, thereby reducing battery consumption and ensuring the alarm is not inadvertently switched off when there is a fire. |
