Copyright © 2019 Nortek Security & Control LLC24Connect the Hardwire LoopsThe GC3 Panel supports up to two (2) wired zones. Typically, these zones are used for hardwired Door/Window contactsensors. You first install the contact sensors and then route the loop wiring to the GC3 Panel. This type of connection iscommonly referred to as hardwire loops.IMPORTANT: The GC3 Panel’s hardwire loops are designed to support contact sensors such as magnetic reedswitches or pressure pads. They are not designed for hardwire smoke detectors, carbon monoxide detectors,motion detectors, or glass break detectors.TIP: If you are planning to upgrade the existing wired security system at the home or business to a wireless systemor if you have a need to retrofit any pre-wired sensors in newer construction for wireless, you can purchase the2GIG Hardwire Conversion Kit ( 2GIG-TAKE-KIT1) .To install the hardwire loop wiring for the contact sensors:1. Install the wired contact sensors.2. Route the contact sensor’s loop wire(s) through the back of the GC3 Panel’s wiring cutout.3. Use the diagram below as a guide for connecting the sensor’s loop wires to the GC3 Panel terminal block.» Normally Closed (N/C): Used for Normally Closed (N/C) circuits. This means the circuit on the contact switch isclosed when the magnets are aligned on the door/window contact. When armed, the GC3 Panel activates an alarmsignal it detects that the door or window is no longer in the normally closed state.» Normally Open (N/O): Used for Normally Open (N/O) circuits. This means the circuit on the contact switch is openwhen the magnets are aligned on the door/window contact. When armed, the GC3 Panel activates an alarm signalwhen it detects that the door or window is no longer in the normally open state.» End-of-Line Resistor (EOLR): Used to supervise the sensor for open or short circuit conditions with an End- of-Line Resistor (EOLR). If EOLR supervision is required, you must install a 2.2 kΩ resistor (not supplied). End ofLine Resistors must be installed at the location in the loop farthest away from the panel. This feature allow for theuse of an EOL resistor for existing zones.NOTE: For compliance with UL 38: Manual Signaling Boxes for Fire Alarm Systems, stranded conductorsclamped under wire binding screws or similar parts shall have the individual strands soldered together or shall beequivalently arranged.Wiring Diagram—Hardwire LoopsTIP: After the installation is complete, you must program the wired zone into the GC3 Panel. During programming,you must define the normal state of the circuit for each wired zone. See “Program a Wired Zone.”
