GENERAL
The range of intelligent AV devices are designed to be connected to analogue addressable re
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).
The sounders have three volume levels and 32 tone sets. Models (MI-WSO-XX-I, MI-WSS-XX-I,
MI-WST-XX-I) containing the character ‘I’ after the Customer ID code include in built isolation
providing short circuit protection of the loop.
Up to 159 addresses are available. (consult the panel instructions to conrm compatibility)
These are selected via the two rotary switches. The ‘tens’ digits go 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.
INSTALLATION INSTRUCTIONS FOR WALL MOUNTED LOOP POWERED
ADDRESSABLE SOUNDERS, SOUNDER STROBES AND STROBE ONLY
INSTALLATION
Afx B501AP to a suitably at wall. Terminate
the cable to the appropriate terminals. For
surface mount wiring the cable can enter the
B501AP base via the break outs provided.
Select the appropriate
Tone and Volume settings
via the DIP switch.
Locate the main
assembly on to the base
by rotating until it locks
into place.
CONTINUITY SPRING
The B501AP
incorporates a
continuity spring
between terminals
2 and 4. This allows
the continuity of the
eld 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.

Note: This product is classied as a category `O` device to EN54:23 standard for visual alarm devices. Only variants supplied
with a clear lens will be approved to ‘O’ Class (WSS-PC-*** and WST-PC-***)
At an installation height of 2.4m and any given orientation, the specied light coverage shape and value is achieved. This
is approximately a cone of light projected at 60° base angles from the device centre with a depth and diameter of 2.0m. An
exact coverage shape can be seen by downloading the following drawing from the KAC website, 132962-IAV-O-CLASS-
EN54:23-WST.pdf, 133005-IAV-O-CLASS-EN54:23-WSS.pdf
Model types using a translucent red or amber lens are not EN54-23 approved. These model types must not be used as
visual alarm devices to provide a primary warning notication of re.

VOLUME SETTINGS
Volume setting is selected by SW6 and SW7
of the 8 way DIP switch. The appropriate tone
set is selected by SW1 to SW5 of the 8 way
DIP switch (see table 1) The 2nd stage tone
(related to the 1st stage tone) is controlled by
the re panel via the protocol.
