Elmdene 7422-sfg-g3f Manual

The Elmdene 7422-SFG-G3F module interfaces with standard Grade 3 intruder control panels using a core terminal array. Before wiring, ensure the panel is powered down and the standby battery is disconnected to prevent short-circuiting.

Here are the top five failure scenarios and what the Elmdene manual advises: elmdene 7422-sfg-g3f manual

With the magnet present, find the pair with ~0.5 ohms — these are the Alarm wires. The unit includes an End-of-Line (EOL) resistor network

The unit includes an End-of-Line (EOL) resistor network for tamper zone supervision, configurable by cutting specific wire links to match your panel's required resistance. The available values are typically 0Ω, 1kΩ, or 4k7Ω. For instance, Honeywell Galaxy panels commonly require a 1kΩ EOL value. If you are not an experienced security engineer,

If you are not an experienced security engineer, please contact a local, registered alarm company. Incorrect installation can not only leave your property vulnerable but can also damage the sounder or your alarm control panel.

The Elmdene 7422-SFG-G3F features a multi-terminal strip. Correctly mapping these connections to your control panel ensures the tamper circuit, strobe, and sounder trigger operate seamlessly.
