24 zone fire control panel, Bentel J424/8 EN54 (Italy)

Description
Expandable fire control panel.

Designed and made according to EN54 standards, the J424 is a microprocessor based control panel for medium and large applications. It has 8 zones main board and supports two J400- EXP8 expander modules, for a total of 24 zones and 504 detectors. Each detection zone is equipped with an alarmrepeat output for selective alarm management in the event of fire. The control panel has supervised and silenceable alarm outputs for the control of the self-powered sirens, piezoelectric sirens, fire bells, flashers, telephone diallers, etc. This easy-to-use control panel is protected by a lockable frontplate which allows operational access to authorized personnel only. The J424 control panel is also available with a backlit display, which shows all the information regarding the control panel status. The optional Software in Windows™ environment, allows full systems management of events memory, files, reset and all the programmable functions provided by the control panel.
