Description

Three sensing technologies work together in this S200A detector: photo, thermal and infra-red, arranged as a multi-criteria, multi-sensor device. Speed of response for a fast flaming fire is comparable to ionisation technology, while the multi-criteria arrangement makes the detector less susceptible to false alarms.

The white head is an analogue addressable field device working to the System Sensor Protocol. It is installed in B501AP base, giving an installed diameter of 102mm, and takes 15 to 32Vdc. Standby draw is 200 µA at 24Vdc where there are no communications, and 300 µA at 24Vdc with LED blink set to once every 5s, plus 3.5mA at 24Vdc of LED current. PC/ABS forms the moulding, wire gauge at the terminals tops out at 2.5mm², and the detector carries a -30°C to +70°C rating.

Read the full technical description

The 22051TLE-26 is an S200A smoke/thermal/IR sensor in white, a multi-criteria, multi-sensor detector that brings photo, thermal and infra-red sensing into one head. That mix offers comparable speed of response to ionisation technology for a fast flaming fire, and leaves the detector less susceptible to false alarms.

The detector is grouped with System Sensor Protocol Analogue Addressable Field Devices, and its supply window runs 15 to 32Vdc. Maximum standby current is 200 µA at 24Vdc with no communications, rising to 300 µA at 24Vdc once LED blink is enabled to run once every 5s; a further 3.5mA at 24Vdc is attributed to the LED.

The housing is moulded in PC/ABS and finished White, terminals accept a maximum wire gauge of 2.5mm², and the detector measures 102mm across when installed in B501AP base. Ambient conditions may run between -30°C and +70°C, in 10 to 93% relative humidity (non-condensing).
