ELV - Low Voltage Systems

EST3 has a wide selection of cabinet arrangements allowing the greatest use of EST3’s flexible modular design. Lobby enclosure wallboxes are manufactured from #14 AWG cold rolled steel with a gray baked enamel finish. Lobby enclosure doors are manufactured from #14 AWG cold rolled steel and have a modern contoured door design with integral viewing window. The exception is the small lobby enclosure 3-CAB5. The 3-CAB5 wallbox and non-contoured door are #16 AWG cold rolled steel. Lobby enclosure doors come with gray baked enamel or optional red baked enamel finishes. The EST3 lobby enclosures back boxes, doors and chassis units are ordered and shipped separately. The 3-CAB5 lobby enclosure comes complete with door and back box providing space to mount five local rail modules. The EST3 remote closet cabinet design allows the installation of control panel electronics in electrical closets. The remote closet cabinets have left hand hinged doors and are available with red finish only. Optional display modules used for system diagnostics display, mount behind the closet cabinet door and are not visible with the door closed.

The Main Display interface is the primary user interface in the EST3 Life Safety System. The main display interface focuses on the emergency user by putting information important to the user up front. Hands free, the first highest priority event is shown. The display always gives the last highest priority event. Arriving at the panel and without opening the door the first and last alarm is given. Simple to understand lights and switches help the emergency user execute system commands with confidence. A menu system supports maintenance functions such as disables or reports for use by staff or service personnel.

The Edwards EBPS Series Booster Power Supply is UL 864, 9th Edition listed. It is a 24V DC filtered-regulated, and supervised unit that can easily be configured to provide additional notification appliance circuits (NACs) or auxiliary power for Mass Notification/ Emergency Communication (MNEC), as well as life safety, security, and access control applications. The EBPS contains circuitry to monitor and charge internal or external batteries. Its steel enclosure accommodates up to two 10 amperehour batteries. It has four Class B (convertible to two Class A) NACs that can be activated in one or two groups from its unique dual input circuits. The EBPS is available in 6.5 or 10 ampere models. Each output circuit has a capacity of three amperes
