3 SigTEL Compact Components
Note: See Specification (section 19) for component details.
3.1
MCU (part nos. ECU-4, ECU-8, ECU-16)
The master control unit (MCU) controls the EVCS and allows the MCU’s Operator
to communicate with the outstations.
Each MCU has either four extensions (ECU-4), eight extensions (ECU-8), or 16
extensions (ECU-16).
One extension typically has one outstation (Type A or B) or a DPTA connected.
A flush bezel (AFP385) and an anti-tamper enclosure (BF359/3D) are available
to house the unit.
Note: Up to 14 MCUs and LCUs can be connected on a network by installing a
Network Communications Card (ECU722) in each unit.
3.2
LCU (part no. ECU-8NT)
The line control unit (LCU) is identical to an MCU but it does not have a handset
mounted on its front. Each LCU has eight extensions.
3.3
Grey flush bezel (part no. AFP385)
This flush mounting bezel is used with the MCU/LCU and provides a neat finish when an enclosure is semi-recessed
(up to 60 mm).
3.4
Type A Fire Telephone Outstation (part nos. EVC301RPO, EVC301RLK)
One Type A outstation is connected to one extension so that the control room can call out to
specific locations and also know which location is calling in.
The outstation consists of a telephone-style handset housed within a wall-mounted, red steel
case. Two versions are available a magnetic ‘push to open’ version (EVC301RPO) right, and
a ‘lift lock’ version (EVC301RLK) used to prevent unauthorised access.
Both units can be surface mounted, or a flush mounting bezel (T-BEZ301) is available.
3.5
Flush -mounting bezel (part no. T-BEZ301)
This red flush bezel provides a neat finish when a Type A fire telephone is semi-recessed.
3.6
Type B Disabled Refuge Outstation - surface mounted (part no. EVC302S/GS)
One Type B outstation is connected to one extension so that the control room can call out to
specific locations and also know which location is calling in. The EVC302S has a stainless
steel fascia and the EVC302GS has a green mild steel fascia. Both units use hands-free,
duplex operation and have a ‘Push to Call or Answer’ button, Call in Progress LED, buzzer
and apertures for a microphone and loudspeaker.
