How does the Sonic wireless door sensor detect if someone opens my front door?

The device operates using a two-piece magnetic system: a compact sensor mounted on the door frame and a magnet attached directly to the door itself. When the door is closed, they form a secure magnetic circuit. Opening the door breaks this field, causing the sensor to transmit an instant emergency signal to your central alarm.

Can these magnetic contacts be installed on heavy composite doors?

Yes. Our local installation team configures these sensors to work flawlessly across all modern Irish residential door types, including high-insulation composite doors, uPVC framing, heavy timber, and sliding aluminum back doors.

Can I set my house alarm to only activate these door sensors at night?

Yes. During our on-site programming, we customize your security zones. This allows you to activate a "Stay Mode" or night setting, which arms all your perimeter door sensors while allowing you to move freely inside your home without setting off the main sirens.

What happens if someone tries to slide a knife behind the sensor to bypass it?

The sensor is protected by an intelligent, integrated anti-tamper switch. Any physical attempt to pry the device away from the door frame, smash it, or slide tools behind the casing will immediately bypass the normal arming status and trigger an instant, high-priority system alarm.

Double the Protection, One Discreet Sensor

Why Choose the Sonic Wireless Door Contact Sensor?

High-Precision Magnetic Detection: Utilizes an advanced internal reed switch and a powerful, compact magnet. The instant the physical connection between the door and the frame is broken by even a few millimetres, the sensor triggers an immediate alert.
Instant Encrypted Transmission: Linked directly to your central Sonic smart home panel via secure, encrypted channels. Any unauthorized opening fires your property’s internal and external sirens while sending an immediate push notification to your phone.
Low-Profile Architectural Integration: Designed with a sleek, minimalist casing that mounts cleanly onto composite, uPVC, timber, or aluminum doors without disrupting your hallway's design or entryway styling.
Smart Battery Management & App Alerts: Continuously monitors its own power usage and signal strength, sending automated notifications to your smartphone app months before a battery change is needed.
Integrated Anti-Tamper Security: Equipped with an on-board physical tamper switch that triggers a system-wide alarm if someone attempts to pry the sensor off the frame or open its casing, even when the system is unset.
Certified 10-Year Sonic Structural Warranty: Professionally aligned, tested, and backed by our comprehensive Sonic Security Systems 10-year warranty.
