Magnetic contact (two-way) with 2 inputs/outputs (wireless expansions)

Defining this device as a magnetic contact is somewhat reductive. Besides providing two positions for the magnet, 90 degrees one from the other for device placement optimization, the MC300 magnetic contact provides 2 terminals which can be configured individually as input or output terminals.

Configuring the terminals as inputs provides standard zone management (NO, NC, Single Balancing; Double Balancing), and also allows direct connection of shock and rollerblind detectors.

Configuring the terminals as outputs grants access to a 50mA open-collector output.

Alarms deriving from the magnetic contacts, and distinctly from the 2 terminals, will be signalled separately on the control panel. This device provides an option which allows you to change the “unused”magnetic contact (of the two present on the device) into a magnetic tamper protection. In this way, it will be capable detecting tamper attempts using magnets.

This device is protected against dislodgement and open-cover tamper. MC300 is available in brown, black or white.

Frequently security professionals perceive the market need for a reliable, truly proficient wireless system. And now, thanks to INIM’s perception of installer company needs, that system is available.

The first-rate “Air2” wireless system operates over 868MHz band and moreover uses two-way signal transmission technology. This means that all the system devices transmit and receive signals. This two-way transmission technology also means that the traditional receiver has been replaced by a superior device that not only receives but also transmits signals to all the system devices.

Therefore, the “Air2” system does not rely on one-way alarm signal transmission, like most wireless systems, but verifies the successful effect of the signal on the target device via a two-way wireless transmission channel. Security professionals will find the innovative operating principles and superior functions of the “Air2” wireless system more than convincing and will surely appreciate the advanced features of the system diagnostics.

The transceiver connects directly to the control panel I-BUS (INIM’s peripheral communication bus) and allows fully-integrated management of all wireless and hard-wired devices. INIM’s “Air2” high-performance wireless system provides complete protection and in no way lowers security. Choosing “Air2” means reducing installation time to a minimum whilst at the same providing those hard-to-get-to spots with total protection. The “Air2” wireless system can be installed without defacing the structure it protects, and therefore finds its niche in buildings of importance such as churches and museums where extensive structural work would spoil the overall appearance of the building.
