The 22051TLE-34-IV is a detector that uses software algorithms to combine Photoelectric, Thermal and Infra-red sensing elements with analogue addressable communications giving reliable fire detection whilst allowing the detector to reject many common causes of nuisance alarm. Valid addresses on F100A and F120A are 1 to 99.

Features

• Unique, true three sensor multi-criteria fire detector incorporating photo, thermal and IR sensing elements Advanced algorithms interpret and respond to the multiple inputs
• Viable performance replacement to the ION detector
• Six available sensitivities
• Fully integrated infrared sensing to support the fire alarm decision
• Automatic drift compensation of smoke sensor
• Rotary decade address switches, 1 to 99
• Dual red LEDs for 360º visibility
• Optional remote LED accessory
• Magnet test function bypasses inbuilt delays
