TECHKO Pool Alarm S187D — UL-compliant 110–115 dB pool safety alarm with patented screen-door sensor

TECHKO S187D Safe Pool Alarm is a UL 2017–compliant pool safety alarm that sounds a 110–115 dB, six-tone alert whenever the protected door or pool area is breached.

If you’re responsible for a backyard pool, spa, or any barrier that opens to water, the TECHKO S187D adds a robust layer of alerting that helps meet pool-inspection standards and local child pool safety laws. Designed to be simple to mount and weather resistant, this system pairs a primary alarm unit with a patented screen-door sensor so you can keep sliding glass doors open without false triggers from a drawn screen.

How loud and noticeable is the alarm when it activates?

The TECHKO S187D emits a high-output 110–115 dB, six-tone alarm designed to capture immediate attention inside and outside the home. A continuous audible signal is supplemented by visible LED indicators so caregivers can quickly locate the source.

• 110–115 dB multi-tone siren for strong, recognizable warning
• Always-On protection mode to ensure continuous monitoring
• Visual LEDs: blinking status and constant low-battery indicator

Will it reduce false alarms when I open a sliding glass door?

The package includes TECHKO’s patented secondary screen-door sensor that prevents false triggers when the sliding door is open but the screen is pulled. The secondary sensor is designed to work with each primary alarm unit at its installation point, allowing you to keep airflow and natural light without compromising safety.

• Patented screen-door sensor specifically blocks false alarms from screens
• One secondary sensor pairs to one alarm—do not use as an independent alarm
• Clear LED feedback when sensor bypass is active

How do I control entry and temporary access without disarming safety?

Two bypass buttons temporarily silence the alarm for controlled entry or exit; each press disables the alarm for a ten-second window, indicated by a blinking LED. This quick-access feature gives adults time to open doors while preserving continuous protection when not intentionally entering or exiting.

• Two accessible bypass buttons for temporary 10-second muting
• Blinking LED clearly shows when bypass is active
• No need to remove batteries or fully disarm the system for brief access

How durable is it outdoors and what power options are required?

The S187D is built to withstand poolside conditions with an IP65 weather-resistant rating. It operates on a single 9V battery (not included) and includes a constant red LED that signals low battery so you can replace power before protection lapses.

• IP65-rated housing to resist rain and splashes near pools
• Uses one 9V battery; low-battery always-on red LED warning
• Mounting adhesives and placers included for out-of-reach installation

Who this is for: The TECHKO S187D Safe Pool Alarm is intended for homeowners, pool contractors, and property managers who need a UL-compliant, easy-to-install safety alarm that meets child-pool-safety rules and reduces false activations from screen doors. It’s a practical choice when you want a high-decibel alert, simple temporary bypassing for adult use, and weather-resistant reliability at doors or gate points leading to water.
