Siterwell Smoke Detector, 10-Year Life, Magnetic Fastening, Photoelectric Sensor, Low Battery Warning, 4 Packs

SITERWELL is the only witness laboratory company in Asia with dual accreditation to US and European standards. With Isaac Papier as our technical consultant, we spent 15 million US dollars to clone the United States UL laboratory, which perfectly covers the latest European, Australian, Canadian and American standards. American Standard products have passed all tests, and different laboratories have consistent high test standards.

The GS509A Smoke Detector is a photoelectric smoke alarm with a 10-year battery life. The photoelectric technology makes it more sensitive in detecting slow smoldering fires that generate light smoke and little heat. The smoke alarm has a test/mute button to check its normal operation, and it is designed to be silent and not disturb your rest.

The smoke alarm is designed with a loud >85dB alarm, ensuring that everyone in the house can hear it clearly when it is chirping. If the battery is low, there will be a signal alarm to inform you to change it. The fire detector can be easily installed on the wall or ceiling through the mounting bracket, and it is installed in accordance with the NFPA standard 72, ensuring your trust in our products.

Working smoke detectors can cut the risk of dying in a home fire by 50%, and a home fire starts every 83 seconds. The faster you realize a fire warning, the more time you have to escape from the fire. The GS525A Smoke Detector and the GS508C Smoke Detector are also available, providing you with various SITERWELL products to choose from.

Isaac Papier, the SITERWELL Technical Adviser and former Honeywell Vice President, as well as the UL National Security Council Chairman, has been instrumental in our efforts to provide high-quality and reliable smoke detection products. With their expertise and our commitment to innovation, we are confident that SITERWELL's products will keep your family safe and secure.
