Addressable smoke detector, Detnov, DOD-220A-I

The Detnov DOD-220A-I is an addressable optical smoke detector for use in addressable fire alarm systems. It detects smoke by the optical principle, using scattered light (the Tyndall effect).

The detector includes algorithms that compensate for dirtiness in the optical chamber, which reduces false alarms. It mounts on a Z-200 base and meets EN 54-7 and EN 54-17.

Key features:

• Device type: addressable optical smoke detector, for addressable systems
• Detection principle: optical smoke, scattered light (Tyndall effect)
• False alarm reduction: optical chamber dirtiness compensation algorithms
• Operating voltage: 22–38 V DC
• Standby current: < 300 µA; alarm current: < 11 mA
• Standards: EN 54-7, EN 54-17; certification 0370-CPR-1859
• Protection rating: IP40; operating temperature: -10 … +70 °C (14 … 158 °F); mounting: Z-200 base
