EATON BiWire Flexi Installation Manual (PR215-216-520-03 15-03-16, PINSTFLEXIINST) March 2016 www.eaton.com 17
Installation Instructions
Connecting the Mains Supply
The mains supply should be exclusive to the fire alarm as
detailed in BS5839. A plug and socket is not satisfactory.
We recommend that a switched double pole fused spur unit
is used for the sole use of the fire alarm system and should
be clearly marked with:
FIRE ALARM DO NOT SWITCH OFF
Before connecting the fused spur to the PSE, slide the fer-
rite core (supplied with the panel) over the cable as shown
in Figure 19.
Connect the fused spur to the input marked MAINS on the
PSE, observing correct wiring regulations (see Figure 16).
OBEY VOLT DROP LIMITATION WHEN SIZING CABLES.
USE ONLY APPROVED CABLE TYPES.
DO NOT TIGHTEN TERMINAL CONNECTOR SCREWS
TOO TIGHT.
KEEP POLARITY THROUGHOUT. NON COLOURED
CONDUCTORS SHOULD BE PERMANENTLY MARKED.

Connecting the Battery Supply
A Battery cover is supplied to prevent accidental contact
with the battery terminals and gives additional useful infor-
mation. The battery cover can be moved out of the way as
indicated in Figure 20.
Connect the spade connectors of the two wire battery cable
and the single wire battery cable as illustrated in Figure 19.
Do not connect the plastic socket end of the battery cable to
the PSE until all installation actions in this guide have been
completed and the system is ready for testing.
