Comet The optical smoke detector SD-280
| Previous | 43 / 143 | Next |
code: SD280
Optical smoke detector, relay output, connectable to binary input, powered from 12Vdc.
Optical smoke detector, relay output, connectable to binary input, powered from 12Vdc.
The SD280 detector combines an optical smoke sensor with a heat sensor. Both sensors have their outgoing signals processed digitally, resulting in higher false alarm immunity.
When the detector is used with inserted batteries (3x 1.5 V AA), it can continue operating as a stand-alone detector, when the external 12 V power supply is disconnected.
| Technical parameters | Value |
|---|---|
| Power | 9 – 15 V DC / 3.5 mA (150 mA during an alarm) or 3 pcs of AA 1.5 V alkaline batteries |
| Smoke detector sensitivity | m = 0.11 - 0.13 dB / m pursuant to EN 14604:2005, EN 54-7 |
| Operating temperature range | -10 °C to +65 °C |
| Dimensions | diameter 126 mm, height 52 mm |
