## Long description

Surface-mounted magnetic contact Alarmtech MC 740-PE is a reed-switch type sensor designed for use in intrusion detection systems. Classed as Grade 2, this surface-mounted contact provides reliable contact-triggered signaling when the relative position between a door or window and its frame changes. Its compact housing and straightforward installation make it suitable for visible mounting where concealed wiring is not possible or where a discrete, low-profile sensor is required for residential and commercial alarm installations.
Advantages
The reed-switch mechanism ensures a simple and durable magnetic contact with minimal maintenance and low current consumption. Its Grade 2 classification indicates suitability for standard security environments with moderate risk levels. The surface-mounted design simplifies installation without cutting into frames, and the compact dimensions reduce visual impact while offering consistent switching performance. Built for compatibility with common alarm control panels, the contact supports reliable zone monitoring in wired intrusion systems.
Suitable for
Doors and windows in homes and apartments
Secondary entrances, service doors and office partitions
Commercial premises with standard security requirements
Sites where surface mounting is preferred or necessary
Key specifications
Sensor type: Reed-switch (magnetic contact)
Security grade: Grade 2
Mounting: Surface-mounted for door and frame installation
Output: Contact-triggered signal suitable for wired alarm zones

How to use
Position the main contact body on the fixed frame and the magnet on the moving element (door or window) so that when closed they align at the recommended separation distance. Secure both parts to the surface using screws or adhesive as appropriate for the mounting surface, taking care to maintain correct alignment. Connect the contact wires to the designated zone terminals on the alarm control panel according to the panel manufacturer’s wiring scheme, observing polarity and tamper considerations if applicable. After wiring, test the contact by opening and closing the protected opening to verify that the alarm system registers the state changes correctly.
Usage recommendations
Install on clean, dry surfaces and avoid locations with heavy mechanical stress or direct impact. For best performance, maintain the recommended gap between magnet and switch and periodically inspect mounting hardware and wiring for wear. Use in conjunction with appropriate Grade 2 system components and follow local regulations and alarm system guidelines for zone configuration and monitoring.
