INDICATIONS OF ALARM STATUS
The on-board Twin LED’s indicate the current status of the Sound Unit and the nature of any
Alarm trigger that has occured.
1.
Alternate flashing LED’s - Indicate that the Unit is in stand-by mode ready to operate.
2.
Simultaneous flashing LED’s giving
two
pulses indicates an Alarm trigger resulting from a
Tamper or Alarm activation.
3.
Simultaneous flashing LED’s giving
three
pulses indicates an Alarm
trigger as a result of
power disconnection from the Control Panel. ie. as a result of someone cutting the
connecting cable to the Sound Unit or due to total loss of Power to the Control panel.
INSTALLING MULTIPLE UNITS
If more than one Sound Unit is to be connected to an installation then the current consumption
may exceed the maximum load rating of the Control Panel or Power Supply. Selecting the
SCB
function (as previously described) on secondary units can overcome that problem.
