Voice Alarm DKM18 583506 Fireman Keypad Extension Module

The 583506 Voice Alarm DKM18 is a digital keypad extension module for the digital fireman's emergency call station, adding 18 extra freely programmable buttons that can be labelled, each paired with an LED display element. It expands the call station's reach for larger paging and alarm zone configurations through digital transmission of control signals to the call station for reliable operation.

Designed as part of the D1 Voice Rack range under the Rack Components sub-range, this module integrates with compatible systems such as the DCSF12 fireman's emergency microphone (12 buttons) with redundancy option, referenced by SKU 583503.RE. The DKM18 provides scalable control for complex voice alarm installations requiring additional zone selection and labelling capabilities. It supports custom labelling of each button and corresponding LED indication, enabling clear identification of zones or functions within extended alarm systems. The digital signal transmission helps ensure accurate and dependable communication between the extension module and the primary call station, maintaining system integrity in demanding environments. This configuration allows for flexible adaptation to evolving site requirements without compromising operational performance.
