EDWARDS EST4 SERIES

EST4 has a wide selection of cabinet arrangements allowing the greatest use of EST4’s flexible modular design.
Cabinets support more interfaces and display modules than earlier systems, which means smaller or fewer cabinets need to
be installed to provide the same display capacity. Cabinets also support optional mounting of Signature Series modules, which is another way to reduce the use of external cabinets.

Standard Features
• Left or Right-hand Hinging Doors
Allows the mounting of two cabinets side-by-side with
full access while both doors are open.
• Lag and Keyway Holes
Makes mounting of enclosures quicker and easier.
• Attractive Contour Door Design
Lobby enclosures, annunciators, with their contour door
designs, feature color-matched black wallboxes that
complement distinctive metallic bronze doors.
• Combination Flush or Surface Mounting Lobby Enclosure
Quicker installation with semi-flush trim built-in.
• RCC Series House up to 65 Amp Hour Batteries
Remote Closet Cabinets support larger battery sizes reducing
the number of boxes required.
• Maximum Space for optional Control Display Modules
Inner doors not only support the user interface layer, but
also acts as a deadfront so field wiring remains protected
during system operation.
• Optional Earthquake Hardening
