Allestec Rack Enclosure for the Onguard 800 Series Gas and Fire Control Panel

Onguard 800 System Rack Enclosure

The Allestec model 800 expandable panel accommodates all modules of the 800 series gas and fire suppression family. Constructed of durable .1" zinc chromate plated steel, the heavy-duty housing is designed for rigorous use in industrial and high hazard environments. The standard EIA 19" rack can be custom ordered to any length, occupying minimum space while maximizing configurations. Matching blank modules can be ordered to occupy any open slots. The maximum height of the rack is only 3.5" and is supplied with a locking clear Plexiglas door. An alternative architect bezel kit (shown) is also available.

System Mother Board

The back of the panel assembly incorporates a full-length motherboard allowing the transfer of signal communication between the modules. Durable Phoenix terminal strips are connected to the customer accessible rear panel allowing easy wire insertion by the 45 degree angle of the connectors. The motherboard terminal block connections are designated by the copper etch on the board itself and by the label located directly on the terminal strips.

Power and ground terminals are located below the main terminal strip and accommodate dual power supply connections. This power plane is bussed across the motherboard, supplying power to all modules and their respective appliances connected to the terminals.
