Waterproof Base
INSTALLATION
Affix sounder Base
to a suitably flat
wall.
Terminate the
cable to the
appropriate
terminals.
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.
The low profile base can be screwed to the deep base if
required using the two screws provided.
If the waterproof 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.
CONTINUITY
SPRING
The sounder base incorporates a continuity spring
between terminals 2 and 3. This allows the continuity of
the field wiring to be checked
without the need for the sounder to
be present. Inserting the sounder
will disengage the spring.
Removing the sounder will close the
loop.
ANTI TAMPER LOCK
The sounder base also includes a
tamper resistance feature that when
activated prevents removal of the unit without the use of
a tool.
To activate this feature, carefully,
using a pair of small pliers or
similar remove the tab section in
the wall of the sounder (as
shown). A sprung section of the
base will now snap into this
cavity upon installation of the
device. This prevents the device
being turned to enable its release.
To remove the device once the
tamper resistance feature has
been activated, place a small
bladed screwdriver into the small
hole on the side of the unit and
push the plastic lever into the
hole, away from the sounder. This
will allow the sounder to be rotated free of the plastic
arm.
This feature is non-
reversible.
INSTALLATION INSTRUCTIONS FOR WMSOU WALL
MOUNTED LOOP POWERED ADDRESSABLE SOUNDERS.
MODELS
Non Isolation - WMSOU-RR-P01 and WMSOU-WW-P01.
With Isolation - WMSOU-RR-P02 and WMSOU-WW-P02.
GENERAL
The WMSOU range of sounders is designed to be connected to
analogue addressable fire alarm systems. These sounders 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 WMSOU-
RR-P02 and WMSOU-WW-P02 include in built isolation
providing short circuit protection of the loop.
Up to 159 addresses are available. These are selected via the
two rotary selector switches. The 'tens' digits go from 0 to 150 (0
to F) and the 'units' from 0 to 9. See address settings on reverse.
Volume setting is selected by SW6 and SW7 of the 8 way DIP switch (see table 1). The appropriate tone set is
selected by SW1 to 5 of the 8 way DIP switch (see table 2). The 2nd stage tone (related to the 1st stage tone) is
controlled by the fire panel via the protocol.
