Wiring Options
Identify a suitable mounting location for the sounder on a flat wall. To remove the lid, use a
cross point screw driver to unscrew the lid retaining screw enough turns so that the lid is
released. Grip both sides or by pressure to the lid top, push the lid away from the screw as
shown in the diagram. The lid can now be removed completely Using the sounder as a
template, mark the fixing points on the surface of the selected location. Drill 3 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 No8 panhead screws, fix the sounder to the
selected location. Please note in order for the sounder’s tamper protection to detect unau-
thorised removal from the mounting surface, which is a requirement for grade 3, the bottom
fixing 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
sounder or the flashing LED’s, connect a negative to the common negative terminal
(C-ve) and connect a positive to the appropriate positive terminal ( S+ve or F+ve). To stop the
sound or flashing LED’s, remove the positive. Terminate the wires into the appropriate termi-
nals. The sound and flash can be wired independently or together, see wiring diagrams over.
The default setting for the tone is alternating, to change this to continuous, move the switch
from position S1 to S2.
Please note that continuous tone does not comply with EN50131-4
In addition to the five main terminals there are also two extra terminals which can be wired
independantly to a 12 volt supply from the control panel, this continously powers the two
main LED’s at a lower intensity and can be used to indicate the system status i.e. set/unset.
Once the unit is wired up, replace the lid by reversing the instructions overleaf. Secure the lid
with the screw and finally fit the screw hole plug supplied.
