The SD-606-4R is a wired smoke detector designed for reliable fire detection in a variety of settings. It operates on a voltage range of DC 9V to 35V and features a low standby current of 80 µA, ensuring energy efficiency. In alarm situations, the detector maintains an alarm current of 40 mA or less, with a clear alarm indication provided by a red LED. The unit can be reset either by powering it off or through an automatic reset feature. This smoke detector operates effectively within a temperature range of -10°C to +50°C and can handle humidity levels of up to 95% RH. It supports alarm outputs for remote LED connections in 2-wire setups and relay outputs for 4-wire configurations, with a contact rating of 0.5 A at DC 28V for relay outputs. The sensitivity is calibrated between 0.08 and 0.16 dB/m (±0.1 dB/m), and the unit complies with the EN54-7:2008 standard, certified by TUV lab. With compact dimensions of Ø99 mm x 48 mm, the SD-606-4R is designed for easy installation.
