99-340 ADEMCO Magnetic Contacts Overhead Door

Review ADEMCO New In Package Original Magnetic Contacts Overhead Door

The ADemco 99-340 Magnetic Contact for overhead doors is a reliable and efficient security device designed to monitor the status of your garage door or similar large moving objects. This magnetic contact is an essential component of a security system, as it sends an alarm signal when the door moves beyond its normal range, indicating potential intrusion or unauthorized access.

The contact consists of two parts: a fixed magnet and a moving magnet. The fixed magnet is mounted on the door frame or jamb, while the moving magnet is attached to the door or the moving part. When the door is closed and properly aligned, the magnets are in close proximity, creating a magnetic field that completes an electrical circuit. This circuit closure sends a signal to your security system, confirming the door's closed position.

If the door moves beyond its normal range, such as being forced open or lifted off its tracks, the magnets lose contact, and the circuit is broken. Your security system will register this change and send an alert, notifying you of the potential intrusion or issue with the door. This quick response allows you to address the situation promptly, reducing the risk of unauthorized entry or damage to your property.

Constructed with high-quality materials, the ADemco 99-340 Magnetic Contact is built to withstand the rigors of daily use and environmental conditions. It features a durable, corrosion-resistant housing and is designed to work effectively in temperatures ranging from -4 F to 140 F (-20 C to 60 C). The contact's adjustable sensitivity settings enable you to customize its response to your specific door and security needs, ensuring reliable and accurate operation.

With its easy installation process, the ADemco 99-340 Magnetic Contact makes it simple to add an extra layer of security to your garage door or other large moving objects. The contact is compatible with most security systems and can be wired using standard 2-conductor wires. The included mounting hardware and clear instructions simplify the installation process, allowing you to secure your property in no time.

The ADemco 99-340 Magnetic Contact is more than just a security device; it provides peace of mind, knowing that your property is protected against unauthorized access or potential damage. Its robust design, adjustable sensitivity, and easy installation make it an indispensable addition to any security system.
