CS-PYH
Programmable Smoke & Heat Detector
The CS-PYH is an 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 has an output for remote indication in form of a remote LED or a local sounder.
The CS-PYH 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-PYH 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-PYH can furthermore be configured to detect smoke at 5 different sensitivity levels, the default sensitivity level is 3. Normal.
