7.3 Disabling/restoring of zones from auxiliary switches
Each of the four detector zones can also be disabled via auxiliary
disabling switches. An auxiliary disabling switch is connected between
terminals 1 and 6 (zone 1), 2 and 6 (zone 2), 3 and 6 (zone 3) and 4 and
6 (zone 4).
The zone is disabled as long as the contact is closed.
IMPORTANT: When a zone (detector loop) is disabled the detectors
will also be disabled, while manual call-points will continue to
function.
If a zone is disabled by using auxiliary switches, the operator will not
be able to restore the zone from the front panel.
With each disabling (either from the front panel or from an auxiliary
switch), the output for auxiliary warning of a disabled zone (output 47 -
AUX 1) is activated (e.g. may be used to switch on an auxiliary
indicator lamp).
NB!
All disabling will be restored automatically after a 24-hour time lapse.
• Disabled zones in the BX-10 system designed for agricultural use
and for use on ships will be automatically restored after 4 hours.
