Photoelectric smoke detector 2251CPI

LEDwith visual alarmwith smoke detector

Product Overview
The 2251CPI Intelligent Addressable (IA) C Series photoelectric smoke detector is an updated model designed to improve nuisance alarm immunity while providing continuous smoke-level reporting to the fire control panel. The sensor chamber geometry reduces stray internal reflections and the detector includes on-board drift compensation. Alarm, fault and maintenance thresholds are configurable via the fire panel configuration software and the panel identifies active devices on the loop.

Features

• Intelligent addressable (IA) communication with fire panel
• On-board drift compensation
• Stable communication with high noise immunity
• Smoke sensitivity configurable in the fire panel
• Rotary address switches for loop addressing
• Two red LEDs on the housing indicate alarm/fault states
• LEDs blink briefly when polled; blink can be disabled via panel settings
• Optional remote LED indicator available
• Magnet test function activates detector and bypasses built-in delays
• Compatible with B501AUS, B501AP and other System Sensor IA bases; compatible bases may offer anti-tamper
• Listed to AS 7240.7 by SAI Global StandardsMark (certificate SMHK25312)
