Larson Electronics 3.5W Explosion Proof Smoke Detector - C1D1 - 12-30V DC - Ceiling Mount - IP44 - (4) 3/4" NPT

The EXP-SD-SFC-LV-V1 from Larson Electronics is an Explosion Proof Smoke Detector that is designed for combustible facilities. This 12-30V DC smoke alarm contains three sets of relays, a magnetic test switch and an LED indicator. Constructed of polycarbonate/ABS and copper-free aluminum, the IP44 rated unit is compatible with ceiling mounting applications. The EXP-SD-SFC-LV-V1 is a cutting-edge smoke detector for use in flammable work sites. Equipped with a magnetic test switch and an LED indicator, this low voltage unit operates on 12-30V DC (24V DC nominal). A low output range of 0-20 mA ensures seamless integration with Distributed Control Systems (DCS). The LED indicator flashes once every four seconds on standby mode. When the alarm is activated, the LED light is steady on. The unit will automatically deactivate the alarm after 10 seconds, when smoke falls below the threshold for detection. The explosion proof device contains three sets of relays (total of 8 relay outputs): Smoke Alarm, Trouble and Auxiliary. The 5-amp smoke alarm relay is Form C with normally open and normally closed contacts, as well as normally de-energized operation. The 5-amp trouble relay is Form A with normally open contacts and normally energized operation. The 5-amp auxiliary relay is Form C with normally open and normally closed contacts, as well as normally de-energized operation. The explosion proof smoke alarm is constructed of polycarbonate/ABS, with a copper-free aluminum junction box. When mounted to ceilings, the unit is IP44 rated. This explosion proof detector features a T4 temperature rating and is ATEX/IECEx rated. Wiring/Hubs: The EXP-SD-SFC-LV-V1 contains terminals that accept 14-18 AWG shielded stranded copper wire during installation. Operators may access a total of four, 3/4" NPT hubs to complete electrical connections. Mounting: Operators can mount the explosion proof device on ceilings. Applications: Combustible storage buildings, hazardous locations, chemical manufacturing, petroleum refineries, battery rooms, turbine enclosures, industrial operations and more.
