Detects smoke and heat in a single housing

The multi-sensor detector combines a split-spectrum optical smoke sensor and a sensitive thermistor in one housing. It connects to a polarity-free two-wire loop and works in an addressable system through its built-in microprocessor.

Key features

Two sensorsIt pairs a split-spectrum optical smoke sensor with a sensitive thermistor, and the heat alarm threshold falls in class A2R.

Ultra-low currentMonitoring current stays at 180 µA or below and alarm current at 270 µA or below.

AddressingAn electrical encoder sets the address within the 1–254 range, and it communicates over distances up to 1500 m.

Status indicatorThe red indicator flashes every 6 seconds while polling and every 2 seconds on a fault, and stays lit during an alarm.

Simple wiringThe two-wire, polarity-free connection simplifies field cabling.

Standard complianceIt is designed in accordance with the EN54-5 and EN54-7 standards.
