TechKo Safe Pool Alarm For Doors, Windows, & Gates | S187D

Designed to provide continuous, always-on monitoring for any gate, door, window, or sliding door leading to a pool or spa area, the TechKo S187D Safe Pool Alarm activates the moment a protected entry point opens more than 1/2 inch. When the magnetic contact separates, a piercing 110–115 dB six-tone alarm siren sounds instantly with no arming step required to keep the system active. Two included bypass buttons positioned on either side of the entry point allow adults to temporarily disable the alarm for 8 to 12 seconds for convenient passage, and a patented secondary sensor enables sliding glass doors to remain open for ventilation while protection is maintained through the closed screen door. The S187D is ETL certified and fully compliant with UL 2017 pool safety standards, making it inspector-approved and meeting Child Pool Safety Law requirements. It is rated IP65 for weather resistance and runs on a single 9V battery (not included), mounting easily with the included adhesives and hardware so no hardwiring is needed. The unit is backed by a three-year limited warranty and was named Better Homes & Gardens Best Gate Alarm of 2024.

Highlights

• Loud Six-Tone Siren Stays Armed by Default: The S187D operates in continuous protection mode with no need to arm or disarm the unit, and the instant the magnetic contact separates beyond 1/2 inch, the six-tone alarm sounds at 110–115 decibels with enough volume to carry through the entire home.
• Bypass Buttons on Both Sides: Two bypass buttons — one on each side of the protected entry — temporarily disable the alarm for 8 to 12 seconds when activated, allowing adult passage without compromising protection for children and pets who can't reach or operate the buttons.
• Sliding Door Ventilation Without False Alarms: A patented secondary magnetic sensor pairs with the screen door, so the sliding glass door can stay open for airflow with the alarm armed and only triggers when both the main door and screen are opened at the same time, cutting down on false alerts.
• UL 2017 Compliance and ETL Listing: Third-party laboratory tested and certified to UL 2017 pool safety standards and Child Pool Safety Law requirements, the S187D meets the criteria inspectors look for during new pool build sign-offs and routine pool safety inspections.
• Weather-Resistant, No-Wire Mounting: With an IP65 weather and water resistance rating, the S187D installs on wood or metal gates, door frames, and windows using the included adhesives and hardware without hardwiring or an electrician, and includes a low battery LED indicator plus a three-year limited warranty.
