Serial signal converter

SAFE Serial Bridge

If you have purchased a SAFE alarm system, you are certainly making use of the wide range of options and modern features it offers. And although its main advantage is a broad range of wireless peripherals, when designing more demanding installations you may encounter the need to integrate wired componentswhether these are other products from the SAFE wired category or solutions from third-party manufacturers. This may involve, for example, the additional integration of magnetic contacts, sirens, detectors, sensors or automation elements. The Serial Bridge is intended precisely for such situations. A converter that lets you connect the SAFE central unit (for example Hub 2 Plus LTE) with the IO Expander Board or IO Relay Board expansion modules. Your purely wireless control panel thus instantly becomes a hybrid one, allowing you to make full use of wired peripherals without technical compromises.

Description of the Device

Fully utilizing the potential of the SAFE system

The SAFE Serial Bridge is not a product you would control directly via the ProSAFE app on your phone, but it is a key “bridge” that enables the SAFE system to be extended with wired peripherals, while also making full use of the potential of the SAFE central unit. The alarm system thus gains far greater modularity, thanks to which the premises can be protected much more comprehensively and effectively.

System flexibility

Thanks to the SAFE Serial Bridge, you are not limited to the basic options of a wireless solution. You can further expand the system with additional wired elements as your needs grow. The module makes it possible to modernise existing installations without having to replace functioning equipment. Simply connect older security elements to the SAFE platform and you gain management via the ProSAFE app, automation scenarios and detailed notifications on your smartphone, all without any further complicated programming.

Installation without complications

As this is original SAFE-branded accessory, communication between the components remains stable and fast, which is absolutely essential in security. The device is very small and there is no need to find a separate power supply for it. The module is powered directly from the RS-232 port of the central unit, so the integrator can easily connect it to the system. Thanks to its compact dimensions, the module can easily be placed in cable routes or directly near the control panel, without requiring a complicated installation solution.
