Common Terms

Supervision

Periodic “heartbeat” signal that confirms the device is active and connected.

Walk-Test

A test mode where the detector’s LED flashes on motion to verify coverage.

Pet Immunity

Low-sensitivity setting/jumper to ignore small pets (up to ~40 lbs).

Zone

The logical partition on your alarm panel where the detector is assigned.

RF Range

The maximum wireless distance between sensor and receiver/panel.

Installation & Mounting

1. Choose Location: Mount 7.5′ above the floor on a stable wall—avoid windows, HVAC vents, and direct sunlight.
2. Mark & Drill: Use included wall anchors and screws—drill pilot holes at 7.5′ height.
3. Attach Backplate: Secure the plastic backplate using the two anchors and screws.
4. Install Battery: Pull down the screw on the bottom of the cover, open, and insert CR123A battery.
5. Snap On Detector: Place the main body onto the backplate and secure with the bottom screw.
6. Restore Power: Ensure panel is powered; detector should supervise in seconds.

Programming to Your Panel

Tip: Refer to your panel’s installation guide for “Learn-In” mode.

1. Put your panel into sensor enrollment (Installer Toolbox ▶︎ Add Sensor).
2. Trigger the detector’s tamper switch by pressing the back cover—panel will show the new zone ID.
3. Assign zone type: choose “Interior Follower” for burglary or “Motion” for activity.
4. Name the zone (e.g., “Living Room Motion”).
5. Save and exit programming—panel will reboot in a few seconds.

Walk-Test

Verifies proper coverage and RF supervision before finalizing installation.

1. On your panel, enter Installer Toolbox ▶︎ Walk Test.
2. Open the detector cover and place a magnet over the tamper arrow—LED will flash on motion.
3. Stand ~6–8′ from the detector and walk across its field of view—LED should flash once per motion.
4. Check all coverage zones; adjust mount angle if any blind spots appear.
5. Exit Walk-Test on panel when finished—LED stops flashing.

Pet Immunity Setup

Helps prevent false alarms from small pets.

1. Open the cover and locate the two PCB jumpers: SENSITIVITY (right) and PET IMMUNITY (left).
2. Leave SENSITIVITY at Low (default) for normal operation.
3. Set PET IMMUNITY to Enabled to ignore animals up to ~40 lbs—disable for no immunity.
4. Reinstall battery and cover; re-run Walk-Test to confirm detection with pets present.

Advanced Installation Tips

• Avoid Air Currents: Don’t point detector toward fans, vents, or open windows.
• Corner Mounting: Provides wider coverage—mount in a corner 7.5′ high.
• RF Interference: Keep >1 ft from large metal objects, routers, or other electronics.
• Regular Testing: Perform a Walk-Test every 6 months and replace battery if supervision fails.
• Zone Settings: Use Entry/Exit delays on nearby pedestrian doors to avoid nuisance alarms.

Troubleshooting

• No Supervision: Check battery seating and RF range—remount closer to panel or add a repeater.
• False Alarms: Reduce sensitivity, enable pet immunity, and remove nearby heat sources or moving objects.
• No Motion Trigger: Verify Walk-Test LED flashes; adjust mounting angle and height.
• Battery Low: Replace CR123A immediately—system will alert low battery.
