IR smoke detector 2351PTIRAUS

photoelectricthermalmulti-sensor

Overview
The 2351PTIRAUS is an IA (intelligent addressable) photo-thermal-IR multi-criteria detector combining a photoelectric smoke chamber, dual thermal sensors and an infrared (IR) sensor for Pertronic intelligent addressable fire alarm systems. The smoke chamber is engineered to reduce stray internal reflections and minimise nuisance alarms while the IR and thermal inputs improve detection of fast-flaming fires.

Features

• Intelligent addressable (IA) communication with fire panel
• Photoelectric smoke sensing chamber designed to reduce stray reflections and nuisance alarms
• Dual thermal sensors (one each side) with thermal alarm threshold at 57 °C
• Infra-red (IR) sensor detects flicker typical of flames and increases smoke sensitivity
• Automatic drift compensation for long-term stability
• Rotary address switches for loop addressing
• Dual red LEDs indicate active detectors; LEDs blink when polled (blink can be disabled)
• Optional remote LED indicator and magnet test function for simplified site testing
• Compatible with B501AUS, B501AP and other System Sensor IA bases; compatible bases may provide anti-tamper
• Stable communication with high noise immunity
• SAI Global StandardsMark listed to AS 7240.5 and AS 7240.7 (certificate SMHK25312)
