Ajax Fibra Multitransmitter Black
Ajax Fibra MultiTransmitter is a wired integration module that allows for third-party wired devices to be connected to an Ajax system. With this module, security companies can complement an Ajax system with nearly any device to build comprehensive security solutions for projects of various complexity. Also, the module provides an outdated yet functional alarm setup with all the benefits of the modern Ajax ecosystem, which is more cost-efficient than an upgrade
