2251-COPTIR Multi-Criteria Sensor
2251CTLE intelligent multi-criteria sensor by System Sensor is a plug-in type fire sensor that combines four types of detection capability with addressable communications.
Overview
System Sensor’s 2251CTLE intelligent multi-criteria sensor is a plug-in type fire sensor that combines four types of detection capability with addressable communications. It normally operates at a high immunity level and changes to become very sensitive to fires as soon as fire characteristics are sensed. A photo electronic sensing chamber detects smoke, while a thermal element provides rate-of-rise and fixed temperature heat sensing. Infra-red and carbon monoxide sensing adds further detection ability, giving reliable fire detection whilst allowing the sensor to reject many common causes of nuisance alarm.
Features & Benefits:- Highest nuisance alarm immunity
- Advanced algorithms interpret and respond to the multiple inputs
- Six levels of sensitivity
- CO sensing for fastest response to slow-developing, smouldering fires
- Fully integrated infrared sensing to support the fire alarm decision
- CE
- 2831 14 DOP-IFD112
- EN54-5: 2000 Class A1R / A1: 2002
- EN54-7: 2000 / A1: 2002 / A2: 2006
