Programmable Smoke & Heat Detector

General Description

The CS-PH Ex is an intrinsically safe addressable combined optical smoke and heat detector suitable for use in SIL 1 and SIL 2 environments. It is designed to comply with the standards for the industrial, maritime, offshore and rolling stock markets up to Safety Integrity Level 2 (SIL 2).

The detector is equipped with two LED indicators giving clear visibility of the red local alarm indication.

The CS-PH Ex detects smoke and heat according to classification of EN 54 standard and can be configured to detect the following:

Temperature class (EN 54-5) A1R A2S CS CR
Operating temperature -40 °C to +70 °C -40 °C to +70 °C -40 °C to +70 °C -40 °C to +70 °C
Application temperature -40 °C to +50 °C -40 °C to +50 °C -40 °C to +80 °C -40 °C to +80 °C
Response temperature +54 °C to 65 °C +54 °C to 70 °C +84 °C to 100 °C +84 °C to 100 °C
Response to increasing temperature (10 °C/min), from typical application temperature 25 °C: 60 to 260 sec No alarm response No alarm response 55 °C: 120 to 330 sec

The CS-PH Ex can also detect multi-criteria heat assisted smoke according to Test fires TF2-TF5 & TF8 for temperature class A1R, CS and CR, as well as multi-criteria heat assisted smoke for temperature class A2S.

The CS-PH Ex can furthermore be configured to detect smoke at 5 different sensitivity levels, the default sensitivity level is 3. Normal.
