of wired relay devices. If not configured properly, assigning one relay to
multiple systems can result in invalid operation of 5400.
Aux alarms must be enabled to trigger General Alarm. -
General Alarm may still be active even though aux system is no longer in -
alarm. See aux relay information below and General Alarm - page 113.
Aux Hold Off
Aux Hold Off (user configured) is the length of time the control or alarm condition
must exist before the Aux relay energizes.
Notes:
To avoid control or alarm for spurious events, configure the Alarm Hold -
Off to > than 0.
If General Alarm is enabled, it is triggered after the Aux hold off time and -
not the general alarm hold off time.
Digital
Configure digital control/alarm (open/closed), relay, alarms, and hold off in the
Aux 1 and Aux 2 Sensor Setup Menu. Use digital input type for triggering relay to
energize based on either a switch open or switch closed condition. Enabled relay
will energize based on the condition configured in the control/alarm on menu.
Aux Relay Digital
When enabled, Aux digital relay energizes when configured control/alarm on condi-
tion occurs. Aux relay energizes after configured aux hold off time. When alarms
are disabled and as long as control/alarm on condition exists, the relay remains
energized including when menus are entered. Relay de-energizes when a non
control/alarm condition is processed by the 5200A regardless if alarms are enabled.
If alarms are enabled, the relay also de-energizes when one of the four front panel
softkeys
is pressed. Pressing one of four softkeys
resets the alarm system. The Alarm system becomes active again if, after the aux
hold off period, the alarm condition still exists.
Aux digital events (event log) are identified by aux number, input type (digital),
relay condition (on/off), and do not identify digital condition (open or closed).
Aux digital events are not identified as control or alarm events regardless if alarms
are enabled.

Notes:
At sensor log Aux, (1:1.00) is reporting open condition. Aux (1: 0.00) is -
reporting closed condition.
Aux digital relay will energize when alarms are enabled if in menus longer -
than aux alarm hold off time and control/alarm condition is processed
from an existing non control/alarm condition. The general alarm will
not trigger until the user exits to run screen, the control/alarm condition
is reset by processing non control/alarm condition, AND then a control/
alarm condition is reproduced
Do not enable aux digital alarms when the sensor is in the control/alarm -
condition. Enabling aux digital alarms when sensor is in control/alarm
condition can result in the aux system not properly processing the exist-
ing alarm condition.
Analog (0-1VDC, 0-5VDC, and 4-20mA)
Configure control/alarm low and control/alarm high values, relay, alarms, and hold
off in the Sensor Setup Menu.
