5. Operating Instructions
5.1 Normal Operation:
Once installed, the FA6720-R heat alarm is continuously monitoring for rapid temperature increases. The red LED indicator will flash periodically (approximately every 45 seconds) to indicate normal operation.
5.2 Testing the Alarm:
It is recommended to test your heat alarm weekly to ensure proper functionality.
- Press and hold the large TEST/SILENCE button located on the front of the alarm.
- The alarm will sound a loud, pulsating siren at a reduced volume.
- Release the button. The alarm should stop sounding.
- If the alarm does not sound, refer to the Troubleshooting section.
5.3 Alarm Condition:
If the ambient temperature in the room reaches between 54°C and 65°C, the alarm will sound a continuous, loud siren. The red LED will flash rapidly. Evacuate the premises immediately and call emergency services.

5.4 Silencing False Alarms:
In the event of a false alarm (e.g., from excessive cooking fumes that might still trigger it if very dense), press the TEST/SILENCE button to temporarily silence the alert for 10 minutes. The alarm will automatically reset after this period.
5.5 Sleep Easy Function (Low Battery Warning):
When the battery is nearing the end of its life, the alarm will emit a short chirp approximately every 45 seconds, accompanied by a flash of the red LED. If this occurs during the night, you can activate the Sleep Easy function:
- Press the TEST/SILENCE button.
- The low battery chirp will be silenced for 8 hours. The red LED will continue to flash.
- The alarm will still detect heat during Sleep Easy mode.
- Replace the alarm unit as soon as possible, and within 30 days of the first low battery warning.
6. Maintenance
Your FireAngel FA6720-R Heat Alarm requires minimal maintenance to ensure optimal performance.

- Cleaning: Gently vacuum the alarm's vents and exterior casing monthly using a soft brush attachment to remove dust and debris. Do not use cleaning solvents or wet cloths.
- Battery: The alarm features a sealed-for-life 10-year battery. It does not require replacement. The entire unit must be replaced at the end of its 10-year lifespan or when the low battery warning persists.
