Elmdene 7422-sfg-g3f Manual -
For the 6-wire resistored models, the cores are typically identified by resistance values rather than just color. If you need to use it without internal resistors, you can bypass them by selecting specific wire pairs. Alarm: Connect the Red and Black wires. Tamper: Connect the two White wires.
The ideal location is high up on the exterior, out of easy reach. 2.2 Mounting the Sounder
Replace and screw down the outer cover to close the lid tamper switch. elmdene 7422-sfg-g3f manual
| LED D1 (Green) – Mains Present | LED D2 (Yellow/Amber) – Status | Meaning | | :--- | :--- | :--- | | ON (steady) | OFF | Normal AC operation, battery float charging. | | ON (steady) | ON (steady) | AC present, but battery is charging (high current). | | OFF | ON (flashing) | Mains fail – unit on battery backup. | | OFF | OFF | No power (check fuses or mains input). | | ON (flashing) | ON (flashing) | Battery fault – high internal resistance or open circuit. |
A: Unlike switch-mode supplies, linear units use a heavy iron transformer. The manual notes that linear supplies produce less electrical noise, making them superior for fire alarms and analogue access control readers. For the 6-wire resistored models, the cores are
Configuring the on-board settings is critical for system reliability.
Tighten all mounting screws. Ensure the spring-loaded wall tamper switch sits flush and is firmly compressed against the masonry wall surface. Wiring and Terminal Connections Tamper: Connect the two White wires
Route the cable from the control panel through the backplate. Secure the backplate using at least three No. 10 fixing screws. Commissioning: Apply 12V power (H+ and H-). Connect the battery leads (Red to BT+ , Black to BT- ).
