Programming Alarm latch mode
When the device is in alarm mode, it keeps its
condition even if the contents drop below 5-15%
of the L.E.L. This is an alarm latch mode. This
mode is helpful to the technician, to locate the
device which is in alarm condition.
When you connect the device to a conventional
gas panel, the device must have alarm latch
mode. If we want to de-activate the alarm latch
mode, the LD1 jumper must be linked. The link
or the removal should be done when the unit is
not operating. The device is shipped with
activated the alarm latch.
