Elmdene 7422-sfg-g3f Manual [OFFICIAL]
Elmdene 7422-SFG-G3F (often associated with the siren ranges) is a high-security external sounder designed for Grade 3 installations. This "deep guide" covers its wiring, configuration, and critical installation requirements. Elmdene International 1. Core Specifications Security Grade: Grade 3 (EN50131-4). Environmental Class: III (IP67 for contact components if used).
: Internal resistors are wired in a series configuration for most mainstream control panels (e.g., Honeywell, Texecom, Pyronix, Scantronic). Wiring Options Option A: Fully Supervised Loop (FSL / EOL) Wiring
| Parameter | Value | | :--- | :--- | | | 230V AC ±10% (50/60 Hz) | | Output Voltage (Nominal) | 13.8V DC (float charge) | | Output Current (Continuous) | 3A | | Current (Intermittent/Peak) | 4.5A (for 5 minutes, door strikes) | | Ripple & Noise | < 50mV peak-to-peak | | Battery Charging Capability | 7Ah (12V lead-acid or gel) – Up to 12Ah with derating | | Operating Temperature | -10°C to +50°C | | Enclosure Type | IP30 (Indoor use only) | | Fuse Ratings | Primary: T1.6A L (slow blow); Output: Glass 3.15A; Battery: Glass 3.15A |
A (from manual): Yes, but only if the load is <2A average. The charge current (0.5A) will take over 24 hours to recharge a 12Ah battery. Also, the enclosure does not physically fit a 12Ah – you’d need an external battery box (EN 60950-1 compliant).
Connect to the switched bell trigger output of the panel. Ensure the panel trigger polarity (+ or - trigger) matches the sounder configuration. elmdene 7422-sfg-g3f manual
Connect the directly to the global or zone-specific Tamper loop. 3. Step-by-Step Installation Procedures
Ensure the backplate is tightened correctly and the cover is securely locked.
| 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 |
Always connect the internal battery after the main power is applied to the panel to avoid immediate siren activation. 4. Troubleshooting Common Issues Core Specifications Security Grade: Grade 3 (EN50131-4)
