Analogue Addressable Detectors

Pertronic Industries Intelligent Smoke Detectors cater for a wide range of detection applications. Each analogue addressable detector reports the precise location and zone of a fire incident to the fire alarm control panel.

2351PTIRAUS Detector

IA PTIR Multi-Criteria Detector

The 2351PTIRAUS PTIR multi-criteria detector is a combination heat and smoke detector, with supplementary infra-red (IR) sensor, for Pertronic intelligent addressable fire alarm systems.

This detector features a smoke sensing chamber designed to detect smoke and diminish stray internal reflections that can cause nuisance alarms. These features were developed to satisfy stringent nuisance alarm immunity tests defined in the US smoke detector standard, UL 268 edition 7.

A photoelectric sensor measures the smoke density in the sensing chamber. Temperature in the detector’s surroundings is measured by two thermal sensors, one on each side of the detector. In addition, an IR sensor measures the level of infra-red light in the IR sensor’s line of sight.

Capable of responding rapidly to fast-flaming fires, the PTIR is designed to reduce nuisance alarms.

The PTIR becomes more sensitive to smoke if the infra-red sensor detects flickering, typical of flames. In addition, smoke sensitivity increases if the thermal sensors detect a temperature increase that is not enough to trigger a thermal alarm.

A thermal alarm signal is reported to the fire panel if either thermal sensor exceeds 57 °C. This thermal alarm is independent of the photoelectric and IR sensors.

A suitably configured fire panel will display the location of any detector which has triggered an alarm, fault, or maintenance signal.

Features

Intelligent addressable (IA) communication with fire panel
Automatic drift compensation
Stable communication with excellent noise immunity
Fire panel may be configured with separate alarm, fault, and maintenance thresholds for each individual detector
