Sirens connected via Jeweler protocol
Jeweller
— a proprietary communication protocol from Ajax Systems with a stated signal range of up to 2000 m, high response speed (0.15 sec.) and low power consumption. The standard supports several frequencies with automatic switching between them when the level of interference increases or an attempt is made to jam the signal, and it also implements an advanced failure protection system. Jeweler is supported only by devices from Ajax Systems, however, special integration modules are produced that allow you to connect the corresponding alarm sirens to wired and wireless control panels from other manufacturers.No offers found
