Information About 500-081806
The 500-081806 is a Siemens ionization smoke detector built around a dual-chamber sensing configuration for automatic fire detection applications. The detector operates with compatible DB-3S standard or ADB-3 audible bases and receives its operating power through the associated fire alarm circuit. Its electrical design operates at 21 ± 3 VDC with low standby current while providing increased current during an alarm condition. The detector is a legacy device that has been superseded by the Siemens OP121 with a DB-11 base for applicable replacement installations.
Key Features:
- Dual-Chamber Ionization: Uses dual ionization chambers to detect airborne combustion particles associated with developing fires.
- 21 VDC Operation: Designed for a nominal operating voltage of 21 ± 3 VDC from compatible fire alarm equipment.
- Low Standby Current: Draws approximately 100 µA during normal standby operation.
- Alarm Current: Draws approximately 80 mA when operating in an alarm condition.
- Detector Base Compatibility: Installs with a DB-3S standard base or compatible ADB-3 audible base.
- Environmental Rating: Operates from 32°F to 100°F (0°C to 38°C) under its UL-rated conditions.
- Airflow Compatibility: Rated for air velocities from 0 to 300 ft/min in applicable installations.
- Legacy Replacement Reference: Superseded by the Siemens OP121 detector with DB-11 base for applicable system upgrades.
The 500-081806 delivers the reliability and precision required for automatic ionization smoke detection within compatible legacy Siemens fire alarm systems.
