Wiring Options
Identify a suitable mounting location for the sounder on a flat wall. To remove the lid,
unscrew the retaining screw on the front face, grip both sides and hinge the lid up as shown
opposite. Using the sounder as a template, mark the fixing points on the surface of the
selected location. Drill 4 x 5mm holes for the enclosed wall plugs, insert the wall plugs into
the holes, feed the cable through the cable entry point on the sounder and using the
enclosed screws, fix the sounder to the selected location.
Please note in order for the sounders tamper protection to detect unauthorised removal from
the mounting surface, the tamper fixing screw hole must be used, do not overtighten this
screw as this is a one time operation and if broken or damaged the sounder will need to be
replaced.
There are five terminals for the connection of wires as shown above. To activate either the
alternating or continuous sound, connect a negative to the common negative terminal
(GND) and connect a positive to the appropriate positive terminal (#1 or #2). To stop the
sound, remove the positive or negative supply.
Please note that continuous tone does not comply with EN50131-4.
