Dodatak za 2N interfonski sustav 2N 9155198SET razne boje

This discount bundle increases security for entrance doors by combining a tamper switch, an I/O module and a security relay. Each component monitors or controls different aspects of door access: the tamper switch detects opening or removal of the intercom frame, the I/O module provides inputs and relay outputs for integrating sensors and controlling door devices, and the security relay protects the lock from unauthorised manipulation. Components are also available separately.

Advantages

The tamper switch senses if the intercom is opened or the upper frame is removed, adding tamper detection without requiring an extra mounting slot. The I/O module offers two logic inputs and two relay outputs for flexible sensor integration and device control while fitting beneath another module to save space. The security relay is a compact add-on that prevents unauthorised control of the lock and is powered from the intercom it protects.

Key specifications

• Tamper switch: detects opening of intercom or removal of upper frame
• I/O module: 2 logic inputs and 2 relay outputs for sensor integration and device control
• Module installation: designed to be installed under another module, no separate slot required
• Security relay: installed between the intercom power source and the lock to prevent unauthorised manipulation
• Availability: bundle or individual components can be ordered separately

How to use

Install the tamper switch on the intercom to monitor if the unit is opened or if the upper frame is removed. Mount the I/O module in its designated location beneath another module and connect sensors and controlled devices to the two logic inputs and two relay outputs as needed. Place the security relay between the intercom (power source) and the door lock so the relay controls access and prevents unauthorised manipulation. Follow standard wiring diagrams and safety procedures supplied by the manufacturer during installation.

Recommendations

For reliable operation, verify compatibility of the I/O module and security relay with your intercom and door lock models, and ensure connections are performed by a qualified technician or installer.
