Review ADEMCO Nos Security Contact Sensor No Magnets
The ADemco PR-20439WH NOS Security Contact Sensors are versatile and reliable devices designed for use in securing doors and windows in both residential and commercial settings. These contact sensors come as a pair, consisting of a magnet and a reed switch, which work together to detect any separation. When the magnet is separated from the reed switch, an alarm is triggered, notifying you of an intrusion.
The sensors are designed with a sleek, compact profile that allows for a discreet installation. They are also equipped with a tailored fit for doors and windows up to 10 feet wide and 1 inch thick, ensuring accurate and consistent sensitivity to minor openings that may not normally be detected. The sensors also feature an adjustable sensitivity range to accommodate doors and windows with varying gaps and tolerances.
The PR-20439WH NOS Security Contact Sensors are constructed using high-quality materials to provide durability and resistance to harsh environments. The sensor housing is made of a sturdy, UV-resistant plastic material, while the magnet and reed switch are constructed of strong, corrosion-resistant metals. This makes them ideal for use in exterior applications and rooms with high humidity levels.
The ADemco PR-20439WH NOS Security Contact Sensors come with a self-adhesive backing, making installation quick and easy. The sensors can be easily and securely attached to surfaces without the need for drilling, ensuring minimal damage to doors and windows. Additionally, they can be connected to most security systems using the included 5.5ft/1.7m long wires, providing flexibility in installation and system integration.
In summary, the ADemco PR-20439WH NOS Security Contact Sensors are essential tools for securing doors and windows and providing peace of mind. Their durability, ease of installation, and adjustable sensitivity make them an dependable choice for both residential and commercial applications.
