You must use the specific magnet supplied with the contact; they are tuned to work together.
| Symptom | Possible Cause | Action | |---------|----------------|--------| | PWR LED off | No 24V DC | Check external power supply and fuse | | FLT LED steady | Input wiring open or short | Check continuity of zone wiring. Verify EOL resistor value (typically 3k3 to 10k, check panel spec) | | Output not energising when input active | SW1-1 set incorrectly | If using dry contact, ensure SW1-1 = OFF. If using 24V triggered, set SW1-1 = ON | | Intermittent operation | Loose connection or supply ripple | Tighten terminals. Use regulated PSU | | Unit latches but won’t reset | SW1-2 = ON by design | Cycle power or apply reset pulse as described | | OUT LED flashes rapidly | Overload on relay output | Reduce load current below 2A. Add flyback diode for inductive loads | elmdene 7422-sfg-g3f manual

His phone rang. It was the client. A woman with a voice like crushed gravel. If using 24V triggered, set SW1-1 = ON
Wiring a bell box can feel like solving a puzzle. According to community discussions on the Security Warehouse forum, the internal board terminals typically follow this logic: Description Permanent 12V supply from the control panel. BAT- / BAT+
This unit acts as a bridge between a conventional fire alarm control panel (FACP) and auxiliary equipment such as:
