The twin LEDs provide a visual deterrent by flashing slowly when the system is armed.

Unfasten the primary retaining screw on the bottom of the module housing and carefully pivot the front cover upward.

Loop these terminals into the global auxiliary or zone tamper loop on the control panel to monitor for cover removal or wall detachment. 4. Strobe and Battery Commissioning elmdene 7422-sfg-g3f manual

Mark the screw holes for both the contact and the magnet. Ensure they line up perfectly when the door is fully closed.

, the unit relies more on panel commands but maintains tamper signaling via the Comfort LEDs: Flash at ~1Hz to show the system is active. Remove the Comfort LED link to disable them. Elmdene International 4. Installation Deep Dive Orientation:
