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

The TechKo S187D Safe Pool Alarm delivers continuous, always-on entry monitoring for any gate, door, window, or sliding door leading to a pool or spa area. The moment a protected entry point separates by more than 1/2 inch, the magnetic contact breaks and instantly triggers a piercing 110–115 dB six-tone alarm siren, with no arming required to maintain protection. Two included bypass buttons let adults on either side of the entry point temporarily disable the alarm for 8 to 12 seconds for convenient passage, while a patented secondary sensor allows sliding glass doors to remain open for ventilation with protection maintained through the 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. Rated IP65 for weather resistance and battery operated by a single 9V battery (not included), it mounts easily using the included adhesives and hardware without any hardwiring. Backed by a three-year limited warranty, the S187D was named Better Homes & Gardens Best Gate Alarm of 2024.

Highlights

• Always-On 110–115 dB Six-Tone Siren: The S187D stays in active protection mode at all times with no manual arming step, and the moment the magnetic contact separates by more than 1/2 inch, the six-tone siren immediately sounds at up to 115 decibels — loud enough to be heard from any room in the house.
• Two Adult Bypass Buttons: A pair of bypass buttons positioned on either side of the protected entry point temporarily silences the alarm for 8 to 12 seconds, letting adults pass through freely while keeping the alarm inaccessible to and active for children and pets in the household.
• Patented Secondary Sliding Door Sensor: An included secondary magnetic sensor allows the main sliding glass door to remain open for ventilation while the screen door stays closed, triggering the alarm only when both doors are opened simultaneously to eliminate nuisance false alerts.
• ETL Certified to UL 2017 Standards: Fully certified by a third-party testing laboratory and compliant with UL 2017 and Child Pool Safety Law requirements, making the S187D inspector-approved for new pool builds and pool safety inspections in most jurisdictions across the country.
• IP65 Weather Resistance and Tool-Light Installation: Rated IP65 for weather and water resistance, the S187D mounts on wood or metal gates, door frames, and windows using the included adhesives and hardware without any hardwiring or electrician involvement, and includes a built-in low battery LED indicator backed by a three-year limited warranty.
