How Do I Add a PIR100-345 Motion Detector to the GC Touch?

To add a PIR100-345 motion detector on the GC Touch, go to Settings, enter the Installer Code, and touch Sensor Settings, then select an empty zone and touch Quick Add or Manual Add. Once the panel finds the sensor, assign a name and touch Save to finish setting up the new sensor zone.

What the PIR100-345 Does

The 2GIG GC Touch (available in AT&T LTE and Verizon LTE versions) supports the PIR100-345, a wireless passive infrared motion detector that senses body heat and movement inside a room instead of relying on a door or window contact. It communicates with the panel on the 345MHz frequency and enrolls as its own zone in Sensor Settings, a menu limited to Installer Users.

Because it is an unencrypted 345MHz sensor rather than an eSeries encrypted model, the PIR100-345 is configured with Sensor Class set to Unencrypted Sensor during setup. Once enrolled, it can be assigned to any of the panel's 128 zones and given a Group type that controls how it behaves in Stay mode, Away mode, or both.

How to Add the PIR100-345 Motion Detector

1. Disarm the system. The GC Touch blocks entry to Settings while armed, so confirm the home screen shows a Disarmed status before continuing.
2. Tap Settings. The gear icon sits in the top-right corner of the home screen and opens the main settings menu.

Tap the gear icon in the top-right corner of the home screen to open Settings.

1. Enter the Installer Code. Type 1561, the default Installer Code, to unlock the full Installer Settings menu, including Sensor Settings.
2. Tap Sensor Settings. This option appears among the Installer Settings icons and opens a two-panel screen listing all 128 zones on the left.

The Installer Settings menu includes the Sensor Settings icon.

1. Select an empty zone. Zones without an enrolled device are labeled (Empty). Tapping one displays the Manual Add and Quick Add options on the right panel.

The Sensor Settings screen lists zones on the left and add options on the right.

1. Touch Quick Add or Manual Add. With Quick Add, trip the PIR100-345 once to send a signal; the panel scans and lists the detected TXID for selection. With Manual Add, choose General Device as the Device Type, select Unencrypted Sensor as the Sensor Class, then tap Learn or type the TXID directly, followed by the PIR100-345 SKU or Device ID.

Quick Add lists the TXID of a detected motion detector for selection.

Manual Add lets an installer set the Device Type, Sensor Class, TXID, and SKU manually.

1. Name the zone and touch Save. Tapping Save enrolls the PIR100-345 into the selected zone, and it will appear in the zone list with its name and a signal indicator.

Managing the PIR100-345 After It's Added

A PIR100-345 that's already enrolled can be edited, renamed, or reassigned to a different Group type from the same Sensor Settings menu it was added through, without needing to remove and re-add the whole zone. If the sensor is being replaced, tapping Reset while the zone is selected removes it from that zone so a new device can be learned in its place. Since the Group type controls how the sensor behaves when the system is armed, changing it, such as switching between Interior Follower and Interior with Delay, immediately changes how that zone responds without any other configuration.

If the PIR100-345 Isn't Being Detected

If Quick Add doesn't find the sensor, confirm the battery is installed and trip the detector again within range of the panel, since the panel only lists a TXID once it hears a signal. Try moving the sensor closer to the panel or repositioning it away from metal surfaces and large appliances, which can weaken the 345MHz signal before it reaches the panel. If Manual Add is used instead, double check that the TXID was typed correctly, since even one incorrect digit will prevent the zone from ever triggering. Once enrolled, a walk test can confirm the panel is receiving a clean signal at the sensor's installed location.

Why the PIR100-345 Is Worth Considering

The PIR100-345 adds a layer of protection that door and window sensors alone can't cover, since it detects someone moving through a room even if they never touch a perimeter opening. It's a practical option for hallways, stairwells, or open living spaces where an intruder could otherwise move through a home security system's protected area undetected while the system is armed Away. Because it's a battery-powered 345MHz device, it installs without running any wires, and its Group type can be set so it stays inactive while the system is armed Stay, letting the household move freely at night while everything else stays protected.

Adding a PIR100-345 motion detector to the 2GIG GC Touch gives your home an extra layer of interior coverage that a door or window sensor alone can't provide.
