Notifier NFX-WCF-WC Installation Instructions
MODELS
NFX-WCF-WC = Beacon Non Isolation
NFXI-WCF-WC = Beacon Isolation
GENERAL
The range of intelligent AV devices are designed to be connected to analogue addressable fire
alarm systems.
These devices must only be connected to control panels that use a compatible proprietary
analogue addressable communication protocol.
These devices receive their power from the loop, and can be controlled via the communication
protocol(s).
Models NFXI-WCF-WC include in built isolation providing short circuit protection of the loop.
Up to 159 addresses are available. (consult the panel instructions to confirm compatibility)
These are selected via the two rotary switches. The ‘tens’ digits range from 0 to 15 and the ‘units’
from 0 to 9.
Note: if the control equipment is not capable of taking more than 99 module addresses, a fault
condition will be generated for every address over 99.

Note: This product is classified as both `C` and `W` category device to EN54:23 standard for visual
alarm devices.
CONTINUITY SPRING
The B501AP incorporates a continuity spring
between terminals 2 and 4. This allows the
continuity of the field wiring to be checked
without the need for the device to be present.
Inserting the device will disengage the spring.
Removing the device will close the loop.
ANTI TAMPER LOCK
The B501AP also includes
a tamper resistant feature
that when activated prevents
removal of the unit without
the use of a special tool.
This method is consistent
with the anti tamper feature
across all devices using
this base. This prevents
the device being turned to
enable its release.
Breakout
For isolator specification refer to document SP11-2848 available on request
Note: Bung seal must
be fitted with the deep back box.

If the deep back box option is required then the
wall gasket must be fitted behind the deep base,
and the sealing o-ring fitted after attaching the low
profile base.

INSTALLATION
Affix B501AP to a suitably flat wall. Terminate
the cable to the appropriate terminals. For
surface mount wiring the cable can enter
the B501AP via
the break outs
provided.
Locate the main
assembly on
to the base by
rotating until it
locks into place.

IP RATING
(IP 21C)
Deep Back box (IP 65*)
To achieve IP21 rating for ceiling mount the IP21
seal must be fitted to the product. For wall mount-
ed applications the IP21 seal is not required to
achieve IP21C.
IP33C is certified by LPCB to EN54-3 and EN54-
23. *IP65 is certified by UKAS Accredited test
facility.
