2.23 THE ALARM STACK, CONTINUED
Through their macro sequences, alarms can control the video system's auxiliary outputs
to manage door latches, gates, lighting, etc.
A maximum of (99) active alarms can be managed by the alarm stack. If this number is
exceeded, the alarm message
Alarm Stack Overflow
is displayed on the monitors, and
any further alarms will be ignored. The keyboard operator must manually clear some of
the alarms from the alarm stack using the
key on the keyboard.
2.24 AUXILIARY CONTROL OUTPUTS
Auxiliary control outputs are general- purpose output circuits (relay contact or opto-
output), which can be used to control devices and equipment external to the normal
video system's equipment.
Unlike camera PTZ control or VCR remote control etc., auxiliary control outputs are not
related to any video input source or dependent on any particular video selection prior to
activation.
They are controlled by pre-programmed macro sequences assigned to alarms, general
purpose system macros, or maybe special function keys on the keyboards.
The MAXPRO-Net system supports a maximum of 9999 auxiliary control outputs. Some
possible uses of auxiliary control outputs are:
•
Operating mimic panel indicators,
•
Area lighting control,
•
Controlling electric door lock mechanisms,
•
Remote controlling of boom gates.
