FM500 Fire Button Overview
The FM500 fire button, equipped with a microprocessor and short circuit isolator, is designed for manual alarm signaling on fire protection systems. This innovative device automatically stores the thirty measurements before and the thirty measurements after an alarm condition, allowing a detailed evaluation of the operating conditions.
Advanced Features
Measurements can be displayed in graphic or text form on the control panel display, which is very useful for post-event analysis. In addition, the two-color LED provides a clear indication of the button status:
- Steady red: Alarm status
- Flashing red (2s): Alarm status with operating voltage < 17V
- Slow flashing green (2s): Normal status
- Fast flashing green: Duplicate address
