Poolguard GAPT-2 Pool Gate Alarm – UL 2017 Water Hazard Entrance Alarm The Poolguard GAPT-2 is an outdoor-rated gate/door alarm designed to help alert you when a pool gate (or exterior door) leading to the pool area is opened. It uses a sensor switch and magnet to monitor the gate and sounds an audible alarm if the gate is opened without using the adult pass-through feature. Key Features Part Number: GAPT-2 Compliance: Meets UL 2017 (water hazard entrance alarm equipment) Alarm Output: 85 dB at 10 feet Power: 1x 9V alkaline battery (not included) Low Battery Alert: Audible chirp when battery is low Automatic Reset: Resets automatically under normal use conditions Adult Pass-Through: Built-in pass-through switch for adult entry/exit Outdoor Rated: Designed for outdoor gate installations How the Alarm Works Standard operation: When the gate opens, the alarm gives a brief window to press the pass-through switch. If not pressed in time, the alarm will sound (even if the gate is closed again). Adult pass-through: Pressing the pass-through switch shortly after opening the gate provides a short delay to pass through and close the gate before the alarm sounds. Reminder if left open: If the gate is left open, the alarm continues to alert until the gate is closed and the pass-through switch is pressed to silence. Installation Notes Mounting height: Install the alarm at least 54 inches above the gate threshold. Sensor alignment: The sensor switch mounts to the fixed post/frame and the magnet mounts to the gate so they line up when closed. Acceptable gap: Typical spacing between the sensor and magnet is up to about 2 inches (metal gates/posts may require a smaller gap). Wiring: Includes sensor wiring for typical gate installations (mounting hardware varies by setup). Battery & Operation Uses a standard 9V alkaline battery (not included). Battery life is commonly about 1 year under typical use (varies with alarms and climate). Test the alarm regularly by opening the gate and confirming the alarm sounds as expected. Safety Note This is a safety alarm system and is not a life-saving device. Always supervise children and use layered pool safety measures.

Keep the sensor and magnet clean and firmly mounted—loose hardware can cause missed triggers. Confirm the gate self-closes and latches correctly; a gate left ajar defeats the purpose of a monitored entry point. After storms or windy conditions, re-check alignment and mounting screws for movement.
