Mounting: Use the provided spacers if mounting on ferrous (metal) surfaces to maintain the operating gap. Wiring & Core Identification

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. Standard Resistor Bypass: Alarm: Connect the Red and Black wires. Tamper: Connect the two White wires.

Resistor Identification (FSL Mode): Use a multimeter to identify pairs:

Step 1: Find the pair with ~0.5 ohms (closed circuit) — these are the Tamper wires.

Step 2: With the magnet present, find the pair with ~0.5 ohms — these are the Alarm wires.

Step 3: To identify specific Shunt or EOL resistors, measure between the identified Alarm/Tamper wires and the remaining cores. Manuals & Resources
