Specifications
Full technical data for this part.
| Standards | EN 54 Parts 3, 5, 7, 17 & 18 |
|---|---|
| Max quantity per loop | Up to 100 per loop depending intensity setting |
| Sensor type | Dual Optical, CO & Heat Sensor |
| Sensing states | Eight selectable EN54 sensing states with combinations of optical smoke and Class A1, A2, A2S, B and BS heat sensing enhanced with CO |
| Integral sounder | Integral Sounder (85dbA typical, +3dbA in turbo mode) |
| Vad type | EN54 Visual Alarm Device |
| Sound signals | Integral Sounders will be capable of providing up to 3 different sound signals, which are selected/configured via the main control panel |
| Sound frequency | 910Hz Low Sound; 970Hz High Sound |
| Bell tone | In addition to the voice messages above, an 8 Inch solenoid bell recording shall be provided as a standard complex tone. |
| Optical sensing | Sensing will be carried out by 2 infra-red LED transmitters using separate optical detection angles, processing both reflection and light absorption properties of particles entering the detection chamber |
| Heat sensing | Will be carried out by a thermistor, sampling the surrounding environmental temperature. |
| Co sensing | The CO element shall be incorporated into the optical chamber to sense the presence of carbon monoxide gas emissions from smouldering fires. The CO element shall have a life expectancy of a minimum of 5 years. This element shall be fault and life monitored. |
| Combined sensing elements | This device will combine four individual sensing elements to provide excellent cover for multiple type of fires (Slow smouldering and fast free burning). |
| Led indicator red | Each sensor will possess an integral red LED giving a flashing indication for a fire signal or a continuous indication for certain fault indications. |
