What to do if there is a false alarm from the Ravel RE 150D Control Panel detector?
If you are experiencing false alarms, the detector might be faulty, or the EOL resistor may need checking. First, ensure the AC supply is within 220v±10%. If the issue persists, consider changing the faulty detector.
Why is my Ravel RE 150D showing a hooter fault indication?
A hooter fault indication can occur due to an improper connection in the hooter or a loop fault. If no hooter is connected to the output, verify if the EOL resistor is connected. Inspect the loop wiring for shorts or opens using a meter. If the hooter is non-polarized, ensure each hooter’s +ve loop connects to the 1N 4007 diode’s cathode and the hooter –ve loop connects to the anode of the 1N 4007.
What to do if the Ravel Control Panel has no indication?
If the panel shows no indication, the issue might be a lack of power. Check both the AC power and the standby power.
What to do if the detector OPEN is not detected by the Ravel RE 150D?
If the panel isn't detecting an OPEN detector, the total zone loop current might exceed the rated value. Verify the number of detectors connected in the loop, ensuring the total current doesn't exceed 3mA.
Recommends daily, weekly, quarterly, and annual checks to ensure system operability per IS 2189:1999.
Provides technical specifications for AC Power, Battery, Initiating Device Circuits, Notification Appliance Circuits, and Relays.
Warns about power sources, handling energized units, software reacceptance testing, and environmental conditions.
Describes the 2-zone input circuits, loop resistance, wiring class, and compatible device types.
Details how the panel responds to zone faults, fault restorals, fire detection, and zone isolation.
Explains how to perform a system walk test without triggering the Fire Relay, useful for single-person testing.
