LED/Key Description
Alarm Silence Key and LED
Pressing the ALARM SILENCE key provides a means of
silencing the building’s audible notification appliances (horns).
LED is ON to indicate that an alarm is still active in the system
but the NACs have been silenced (i.e., the Alarm Silence Key
has been used).
System Reset Key and LED
Pressing this key directs the panel to reset all attached devices
and clear all acknowledged alarms, troubles, and supervisory
conditions. All alarms must be acknowledged and all devices
must be reset (i.e., alarm condition or trouble must clear)
before the system can be reset.
System operators must be aware of the following three programmable timers on the AutoPulse Z-
10. Refer to the label on the back of the front cover, which provides a location for specifying the
timer values, for information on the specific timer values used for the facility.

Manual Release Delay Timer . The Manual Release Time Delay is a programmable timer
that specifies the delay between the activation of a manual release switch and the activation of
releasing appliances. The default setting for this timer is 10 seconds. A setting of 0 causes
the releasing appliances to immediately activate after a manual release switch activates.

Automatic Release Delay Timer. The Automatic Release Time Delay is a
programmable timer that delays the activation of the releasing appliance circuits. This timer
starts immediately after receiving a confirming alarm (cross-zoned system) or a first alarm
(single alarm system). When the timer expires, the releasing appliances activate (assuming
the abort switch is not active).
The timer range is 0 to 60 seconds, selectable in 5 second increments. The default setting for
this option is 60 seconds.

Abort Release Time Delay. The Abort Release Time Delay specifies the action that occurs
when the abort switch is released. This option applies only to Agent Release and combination
Agent Release Preaction/Deluge applications (applications one through four and nine through
thirteen in the application matrix described in Table 1-2). Refer to the description of the
Abort Release Time Delay in Chapter 4 of this manual for specific information.
