DC 9V ~ 35V (SD-602-2) Wired Photoelectronic Smoke Detector

The SD-602-2 Wired Photoelectronic Smoke Detector is designed for reliable fire detection, meeting the standards of EN54-7:2008 and certified by CE. It operates with a broad voltage range of DC 9V to 35V, with support for higher voltages up to DC 40-60V. This flexibility allows for integration into various fire alarm systems. The device has a low standby current, making it efficient in terms of power usage: less than 50 µA for both 2-wire and 4-wire configurations. During an alarm condition, the current consumption is 20-25 mA at 12V or 40-50 mA at 24V for 2-wire systems, while the 4-wire configuration draws up to 25-30 mA for normally open (NO) relay contacts and 20 mA for normally closed (NC) relay contacts. The smoke detector features a red LED indicator for alarm status and supports reset options through power cycling or automatic reset. Alarm outputs include remote LED indications for 2-wire systems and relay outputs for 4-wire setups, with a contact rating of 0.5A at DC 28V for the latter. With a sensitivity range of 0.08-0.16 dB/m (±0.1 dB/m), the SD-602-2 effectively detects smoke particles, ensuring early warning in case of fire. Its compact design, with a diameter of 103 mm and a height of 53 mm, allows for easy installation in various settings.
