Abstract (en)
[origin: WO2021111119A1] A detector (10) for a fire alarm system (100) includes first and second sensing elements (14a, 14b) for detecting the occurrence of a fire in a monitored environment. Depending on whether neither, one or both sensing elements (14a, 14b) detects a fire, the fire alarm system (100) is controlled in a different manner to perform different alarm responses. The first and second sensing elements (14a, 14b) may have different operating characteristics, which reduces the likelihood of both bulbs malfunctioning at the same time or for the same reason which may otherwise cause a false alarm.
