3.2 Wiring Connections
The indicator requires a 24V DC power source. Connect the wiring as follows:
- Connect the red wire to the positive (+) 24V DC output from the fire alarm control panel or associated device.
- Connect the black wire to the negative (-) 24V DC output (common ground).
- Ensure all connections are tight and insulated to prevent short circuits.
Refer to the wiring diagram of your fire alarm control panel or duct detector for specific connection points.
4. Operation
The Simplex 2098-9808 Remote LED Alarm Indicator operates automatically in conjunction with the connected fire alarm system.
- When the associated fire alarm device (e.g., smoke detector, duct detector) enters an alarm state, it will provide 24V DC power to the remote indicator.
- The LED on the remote indicator will illuminate, providing a clear visual indication of an alarm condition at its location.
- The LED will remain illuminated as long as the alarm condition persists and power is supplied.
This indicator is designed for continuous operation when an alarm is active. It does not have user-operable controls.
