2.8 Installing the Wiring

2.8.1 External Wiring Connections

The following external wiring must be
terminated at the Termination Board:
a. 28V IN (18-32V dc) and 0V supply, from
previous repeater, or from panel, or from
external source.
Note: If dc power is derived from the fire
control panel, do not exceed the available
current (refer to panel specification).
b. 28V OUT (18-32V dc) and 0V to next repeater.
c. Power Fail (PF) input. Connect to the power
supply unit's power fail output or, if there is
no such output, link the PF terminal to the
0V terminal immediately above it.
Note: If the PF signal goes high or becomes
disconnected, the LCD backlight
extinguishes 10 seconds after the
failure. It illuminates again if any
pushbutton is operated, then extinguishes
again after 10 seconds.
d. RS485 serial data link (A and B) from the
previous station in the network (where
'station' is a fire control panel, repeater or
mimic display).
e. RS485 serial data link (A and B) to the next
station in the network.
Note: Further information about the RS485
serial data link is given in Section 2.8.2.
The following external wiring must be
terminated at the enclosure:
a. Safety earth wire. Connect this to the
safety earth point, which is clearly
marked on the inside top left of the
enclosure rear wall - see 'Detail A'.
Notifier-approved equipment (Network
Gateway Unit) may be connected at the
optional RS232 board as described in
Section 2.8.3.
All external wiring must be screened and
terminated, using any suitable plastic glands,
to meet local wiring codes. Terminate screens
at the repeater earth point (see detail 'A'). To
satisfy EMC requirements, route the wiring
along the edges of the enclosure as shown
opposite. Use cable ties to secure the wiring
at the tie down slots provided.
