4. Tone and Sound Level Adjustment
The Terrier model incorporates 3 user selectable tones. In order to change the tone
setting the front cover of the electronic sounder within the Klaxalarm must be
removed by undoing the two fixing screws. The tones are selected as follows:
Tone Black Lead Jumper
Continuous Cont (-) Terminal Leave in factory setting
Warble Tone (-) Terminal Leave in factory setting
Alternating Tone (-) Terminal Change position
The sound level can be reduced by changing the setting of the potentiometer on
the siren PCB.
5. Connecting External Manual Call Points
NOTE: For correct operation with external manual call points it is essential to use
a call point with a NORMALLY CLOSED CONTACT (i.e. an opening contact
or changeover contact). We strongly recommend the use of Klaxon Manual Call
Point Model No. 17-970073 to ensure correct operation.
The normally closed terminals of the call point should be connected to terminals
A and B in the Klaxalarm using two core cable. The factory fitted link between
the terminals A and B in the Klaxalarm must be removed. Several normally
closed manual call points can be connected in a series loop between these
terminals if desired.
