Precedence and Timing Circuit

The precedence and timing circuit receives alarm signals from
the OR’d logic and sets the alarm group precedence (Alarm
Group 2 always has precedence). This provides two advantages:

It prevents more than one alarm at a time from turning on
the audible alarm

It provides a different output signal for each alarm group:

Group 1 - two seconds on, one second off

Group 2 (with precedence) - one second on, one
second off

Alarms can be acknowledged automatically after a time-out of 1,
4, 8 or 16 minutes. The time-out disables the audible alarm,
turns off any NEW alarm LEDs, and releases relays K1 and K3.
After the time-out period, any new alarms will reactivate the
relays and audible alarm, and restart the timer. When the time-
out function is not used, the relays and audible alarm remain
active until you acknowledge the alarms.

Audio Driver and ACO

When a NEW alarm comes in, the output from the precedence
and timing circuit turns on the audio driver. The audio driver
powers the audible alarm, and the sound alerts service person-
nel of the alarm condition.

On the front panel an ACO (Alarm Cut-Off) switch shuts off the
audible portion of the alarm reporting. A front panel LED
remains on as long as the ACO switch is on. This LED serves to
remind service personnel that the audio has been shut off and
they will not hear subsequent alarms.

Power Supply

The power supply operates on -21 to -56 VDC input power. It
supplies reg5 VDC as well as +12 and -12 VDC power to
the 46017 module’s circuits.
