Up to eight AIU-100 units can be connected to the CCU-100 for 255 alarm
inputs. Up to eight AIF-100/IN units can be connected to the CCU-100 for 64
alarm inputs. A combination of AIUs and AIF-100/INs (totaling eight units) can
be connected to the CCU for various numbers of alarm inputs. The CCU polls
the AIUs and/or AIFs for changes of state (alarms). MultiCalls are programmed
and assigned to alarms.
The CCU accepts 255 alarm numbers from a host computer. When the CCU
receives an alarm number from the host computer, it starts the MultiCall
assigned to the alarm number.
The MX-4248 I/O module has 24 alarm inputs. If the MX-4248 I/O Module is
installed, it replaces AIU-100, address 0, alarms 1 through 32. Alarms 25
through 32 on AIU-100, address 0, are not available. The host computer,
however, can use alarms 25 through 32.
Alarms are acknowledged automatically in the MultiCall assigned to the alarm or
by an operator at the JPD-100 Joystick Controller. Refer to the JPD-100 user's
manual for manually acknowledging alarms. Refer to Section 4, paragraph
4.3.3.4 of this manual for programming a MultiCall to automatically acknowledge
an alarm.
• SHB-100 ShotBox Control Interface
A SHB-100 ShotBox has 16 quick keys. Up to 16 ShotBoxes can be connected
to the CCU-100 Central Control Unit. The user programs and assigns a MultiCall
to the quick key. When an operator presses a quick key, the CCU starts the
MultiCall assigned to the key. If an operator presses the same quick key while
the MultiCall is in progress, the CCU stops the MultiCall.
