Immediately after the detector trips, the area’s sensor
reset relay interrupts power to points connected to it
for the time in
Verify Time
.
When power is restored to the points, the 60 sec.
confirmation window is established. If any detector
reset during the verification time is tripped again
during the confirmation window, an alarm is
generated. If no activity occurs during this period,
no alarm is generated and the verification window
ends. If a verification point trips again after the
window ends, a new verification cycle begins.
Example 2:
Verify Time
is set for 50 seconds. The alarm
verification cycle starts when the detector trips. The
following events happen as described in example 1,
except the sensor reset is 50 seconds.

2.2 Bell Parameters
Area #
Default: 1
Selection: 1 to 8
Enter the area number you are programming.
A# Fire Time
Default: 6
Selection: 1 to 90
Enter the number of minutes the bell rings for fire
alarm points.
The bell output begins as soon as the fire alarm
occurs. When the panel’s internal clock begins a new
minute, it considers the first minute expired. It shuts
off the bell when the programmed number of
minutes expire.
If a passcode is entered to silence the bell before the
time expires, and
Cancel
report is programmed
YES in Phone, a
Cancel
report is generated and sent
to the same phone that the alarm message is routed
to.
Note:
Check with your AHJ to determine the appropriate
time in your application.
The output for the fire bell is determined by
programming in the Relays section of the program.
Relay A is the programmed default providing fire
bell output for all eight areas. Relay A is the D9112’s
on-board relay providing powered alarm output
from terminal 6. An optional D136 Relay can be
installed on the D9112 to provide powered alarm
output from terminal 7 (known as relay “B”).
Because the relay number is programmable by area,
you may change the relay number to provide
separate fire alarm outputs for each area. The relay
assigned provides bell output for the number of
minutes specified in
Fire Time
and follows the
parttern set in
Fire Pat
.
A
Summary Fire
relay is also available in the Relays
section of the program. It does not follow bell
pattern or time.
