FIRE ALARM - OPTICAL 12 V DC/3 X AA

Combination optical smoke detector and heat detector for alarm systems. The optical detector quickly identifies large particles carried by smoke but is less sensitive to smaller particles generated, for example, when alcohol-based liquids ignite. Typically, the heat detector, which responds more slowly to fires, can detect such low-smoke-producing fires faster than the optical detector. The detector is designed to be connected to 12 V DC alarm systems and also includes battery backup. With three AA batteries (not included), the device can continue operating as a standalone alarm even if the 12 V supply is interrupted. • Heat detector: A1 • Alarm temperature: +60°C to +65°C • Built-in siren • LED indicator lights • Alarm output: NO/NC • Operating voltage: 9–15 V DC • Power consumption (standby/alarm): 3.5 mA / 150 mA • Battery backup: 3 x AA (not included) • Battery life: approx. 3 years • Operating temperature range: -10°C to +65°C • Certification: EN14604, EN54 • Dimensions: Ø126 x 52 mm • Weight: 150 g This product description is an automated translation of the original Finnish description.
