Designed and manufactured to EN54 and EN12094-1 standards (with J400-EXT fire extinguishing module), the J424-8 is a microprocessor-based control panel for medium to large applications.
It has an 8-zone motherboard and supports two J400-EXP8 expansion modules, for a total of 24 zones and 512 devices (maximum 32 in each zone). Each zone is equipped with an alarm repeater for selective alarm control in the event of a fire.
The control panel has monitored and disconnectable alarm outputs to control self-powered sirens, piezoelectric sirens, fire bells, flashing signal lights, telephone dials, etc.
This user-friendly control panel is protected by a lockable faceplate, allowing operational access only to authorized personnel.
The J424 control panel also comes with a display that shows all information regarding the status of the control panel. The optional Console software in a Windows™ environment allows full memory management for events, files, resets and all programmable functions provided by the control panel.
