Air Handling Units
Stagger Start
This option allows you to set the AUTOPULSE Z-28 to stagger start any Air Handling Units
(point types AHUR, AHUO, and AHUF) in the AUTOPULSE Z-28 FACP . This option
protects against power spikes that may cause the circuit breakers to trip when AHUs start
simultaneously. The range for stagger starting the AHUs is 0-60 seconds. The default setting
for this option is 30 seconds. A setting of zero allows all AHUs to start immediately.
The AUTOPULSE Z-28 FACP displays an AHU Stagger Start message when the sequence
starts and an AHU Stagger Start Complete message when the sequence ends.
Enable this option by selecting the check box shown below. Refer to Figure 5-2 for the
location of this option.

Active Status Reminder
The Active Status Reminder option allows you to set an interval and duration during which the
AUTOPULSE Z-28 reminds operators that a FIRE, SUPV, or TBL condition still exists in the
panel.
Active Status Reminder consists of two parts. Refer to Figure 5-2 for the location of these
options.

Acknowledge Option. This option sets the duration of the acknowledge signal. The
range can be from 1 to 12 hours, and the default is 5 seconds. For troubles, a setting of 0
sounds a continuous signal until acknowledged from the front panel. For alarms, a setting
of 0 sounds a continuous signal until the alarm condition is cleared.
