Bentel J424-8 Control panel 8-24 zones

Designed and manufactured to EN54 and EN12094-1 standards (with J400-EXT extinguishing module), the J424-8 is a microprocessor-based control panel for medium and large applications.

It has an 8-zone motherboard and supports two J400-EXP8 expansion modules, for a total of 24 zones and 512 devices (a maximum of 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 non-monitored alarm outputs for controlling self-powered sirens, piezoelectric sirens, fire bells, flashing beacons, auto-diallers, etc.

This easy-to-use control panel is protected by a lockable front plate, allowing operational access only to authorised personnel.

The J424 control panel is also available with a display that shows all information regarding the status of the control panel. The optional Console software in a Windows™ environment allows for full management of event logs, files, resets, and all programmable functions provided by the control panel.
