The cards inserted from the front in the internal part of the control unit, while the displays with redundant communication RS-485 will be positioned at the front. In the event of a fault, it will therefore be possible to replace the cards quickly without having to operate on the connection terminal blocks.
All the support terminal blocks coming from the boards are accessible from the rear panel of the switchboard; external side, and engineered for access to the terminal board from the outside; opening the rear door of the panel.
The control unit has specialized boards to control analog / addressed type sensors; conventional cards with collective lines and analog and digital input and output management cards.
The shutdown managed by specialized boards which have the task, among other things, of verifying the discharge; checking the switching of the pressure switch to signal the system’s non-response after an extinguishing command.
On all boards there are touch screen control buttons for various functions; from the visualization of the card diagnostics, to the visualization of absorptions of the operating lines; events (with access levels under password) to the extinction command.
The control panel checks the efficiency of the connections of all the detection lines; it also controls the system used with the sole exclusion of the relay outputs.
The control panel is able to communicate with a remote supervision system; both through lines dedicated to remote surveillance and on a switched telephone line, with automatic call in the event of an alarm. This function allows you to connect several control units to a remote remote management system; using a single telephone line (two in the case of a redundant system).
