Emergency Voice
Communication System
19 Terms and Definitions
For the purposes of these instructions the following terms and definitions apply:
desk control unit
a desk unit that controls the EVCS. Up to 14 units can be installed on a network by connecting to a Network
Communications Card (ECU723) fitted in an MCU wall control unit. Part number: ECU-224.
disabled persons toilet alarm (DPTA) interface
DPTA interfacing is a secondary function to the primary purpose of the system which is to act as an EVCS. Toilet
alarms can only be reset at the alarm point and cannot be reset by the EVCS. DPTA part number: NC951.
emergency voice communication system (EVCS)
system that allows voice communication in either direction between an MCU wall control unit, desk control unit and
a number of other points throughout a building.
extension
each MCU wall control unit has either 16 extensions (ECU-16), eight extensions (ECU-8) or four extensions (ECU-
4). One extension typically has one outstation (Type A or B) or a DPTA connected to it.
line control unit (LCU)
a wall control unit that controls the EVCS. On a networked system, up to 14 MCU and/or LCU wall control units can
be installed. The LCU is identical to an MCU but does not have a handset. Part number: ECU-8NT.
master control unit (MCU)
a wall control unit that controls the EVCS. On a networked system, up to 14 MCU and/or LCU wall control units can
be installed. The MCU has a handset mounted on its front panel. Part number: ECU-16, ECU-8 or ECU-4.
network master
a wall or desk control unit on a network that currently
has control over the EVCS, i.e. the ‘master’. Any other control
unit on a network acts as a repeater. The current master unit can give control to any repeater unit by entering a
security PIN code. There can only be one master unit at any one time on a network.
network repeater
a wall or desk control unit that forms part of a networked EVCS. They repeat messages displayed at the current
master unit and have ability to take control from the master by entering a PIN code.
outstation
unit located at a strategic point in a building, or building complex, that allows two-way voice conversation with either
a wall unit and desk control unit. There are two types; Type A (fire telephone) and Type B (disabled refuge).
type A (fire telephone) outstation
outstation that uses a telephone-style handset for communication. Part numbers: EVC301RPO/EVC301RLK.
type B (disabled refuge) outstation
outstation that uses hands-free operation and has a call/answer button, built-in microphone and loudspeaker. Part
numbers: EVC302S/EVC302GS or EVC302F/EVC302GF.
