Linear DUAL 824 manual Hardwired Loop Wiring, Arm/Disarm Key Station Wiring, Main Terminal Block

HARDWIRED LOOP WIRING

✦The DUAL 824 supports up to eight normally open/closed hardwired loops each with 2.2K end-of-line resistor supervision.

✦Each hardwired loop that is wired and programmed uses one sensor location.

✦Each hardwired loop can be programmed to any sensor number.

✦Each hardwired loop can be programmed as any sensor type, including arm/disarm toggle.

✦Four COM terminals are shared as loop returns for the eight loops.

✦Each hardwired loop has a 400 millisecond response time.

✎NOTE: For UL installations, use UL Listed cable for all hardwired loop wiring.

1.Route wiring from the Control Panel to each hardwired switch contact, sensor, or device. Route the wires through the wiring slot or through a knockout for conduit wiring.

✎NOTE: Maximum recommended hardwired loop length is 500 feet (250' out, and 250' back) for each loop. Maximum loop resistance (excluding the EOL resistor) is 100 ohms.

2.Connect the loop wires to LOOP # and COM terminals. For powered devices connect power wires to +12 VDC and any COM terminal.

3.On the sensor end, connect each normally closed sensor in series with the loop wires. Connect each normally open sensor in parallel with the loop wires. See wiring figure.

4.After the last sensor on the loop, connect a 2.2K end-of-line resistor across the loop.

✎NOTE: Before the hardwired loops will function, they will need to be programmed. This will be covered in the Basic Control Panel Programming section of this manual.

ARM/DISARM KEY STATION WIRING

✦Any of the hardwired loops can be used with a momentary keyswitch to arm and disarm the system.

1.Connect the loop as shown to the keyswitch and end-of-line resistor.

2.Connect an LED indicator from the switch plate to the H/A- and H/A+ terminals.

3.When programming the system, set the loop sensor function to “Type 9, Arm/Disarm Toggle” and set the Automation output to “Active while Armed”.
