The Door Holder - AC Fail Door Drop Timer allows the 4010 to hold doors open for a set
duration during an AC power loss condition. After that duration has expired, the 4010
conserves battery power by shutting off the door holder devices and closing the doors.
The range for the timer is 0-60 minutes, with a default setting of 5 minutes. To have
door holders drop the doors immediately upon AC power loss, set the timer to zero
minutes.
This option allows you to set the 4010 to stagger start any Air Handling Units (point
types AHUR, AHUO, and AHUF) in the 4010 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 4010 FACP displays an AHU Stagger Start message when the sequence starts and
an AHU Stagger Start Complete message when the sequence ends.
The Suppression Release option contains three selections:
•
Dual Detector. When enabled, this option requires two points in L9 (Automatic
Suppression Release Points List) to activate before the outputs specified in L12
(Suppression Release Output Points List) activate.
•
Detector Delay. When enabled, this option allows you to specify a delay between
the time that a detector activates and the time that a point within the L9 list triggers.
The range is from 0 to 60 seconds (60 is the default).
•
Manual Delay. When enabled, this option allows you to specify a delay, ranging
from 0 to 30 seconds, between the time that a manual release point is activated and
the time that the suppression release points in L10 (Suppression Manual Release
Points) trigger.
The Active Status Reminder option allows you to set an interval and duration during
which the 4010 remind operators that a FIRE, SUPV, or TBL condition still exists in the
panel.
Active Status Reminder consists of two parts:
•
Reminder Interval. The range can be from 1 to 12 hours, and the default is 8 hours.
•
Acknowledge Option. This option sets the duration of the acknowledge signal. The
range can be from 0 to 60 seconds, and the default is 5 seconds.
Audible and Visible ON until Silence Notification Appliance Circuits (NACs) can be set to
the choices shown below. The default setting for the Audible NACs is Temporal; the
default setting for the Visible NACs is Synchronous; and the default setting for
QuickAlert Horns is TEMPORAL.
•
Audible NAC Operation – choices are temporal, steady, march time, slow march
time.
•
Visible NAC Operation – choices are steady, march time, slow march time,
temporal, synchronous
•
QuickAlert Horn Operation – choices are steady, temporal, slow march time.
