Isolated Digital Dial ISO-D Range

EDM Series Isolated Digital Dial 'ISO-D' range for Community Housing. Digital dial system for Door Entry with the possibility of Residents' Access Control providing controlled entry for both visitors and residents. The ISO-D system is described as an ‘Isolated’ system, which means that faults on individual handsets and other components will not affect the rest of the system. This increases reliability and facilitates quicker faultfinding. The typical basic standalone system consists of the three main elements. The control equipment is supplied in metal cabinets, connected to the required number of audio/video handsets and entrance panels. These may be selected from the options shown. Any compatible door release or other form of entry control can be supplied according to specification. Entrance panels are digital dial in operation (i.e., combinations of buttons dial apartments in larger complexes). On larger systems slave enclosures are used for phone card connections for system distribution.
