Dip Switch Location and Descriptions
Switch 1: Alarm Verification
If selected, alarm signals that occur on any zone
will be subjected to a two-minute verification
period to determine if the alarm is true. Note that
the control panel will distinguish if the alarm
signal came from a shorting-type contact device
(manual pull station, 4 wire detector, or heat
detector) or a two-wire smoke detector, and will
not employ verification of alarm signals from the
contact devices.
Switch 2: Waterflow on Zone 3
If set , Initiating Device Circuit 3 will function as
a non-silenceable circuit. If an alarm occurs on
this zone, the ALARM SILENCE switch will not
silence any activated output circuits.
Switch 3: Supervisory on Zone 4
If set for Supervisory, Initiating Device Circuit 4
will function as a supervisory circuit. Activation
of a tamper or other supervisory switch on this
circuit will not result in an alarm condition. The
piezo will sound a distinct pulsing tone and the
yellow LED on zone 4 will flash along with the
supervisory LED. Notification Appliance Cir-
cuits 1 and 2 will activate (see Section 3.4).

Switch 4: Silence Inhibit
If selected and an alarm occurs, the
ALARM SILENCE switch will not func-
tion until 60 seconds have passed since
initiation of the alarm. If another alarm
occurs, the timer will restart at 60 sec-
onds.
Switch 5: Disable Bells
When this switch is set "ON", the four
Notification Appliance Circuits and the
SYSTEM ALARM relay will be disabled,
and a local trouble signal will be gener-
ated.
Switch 6: One Man Walk Test
Setting this switch to the "ON" position
places the control panel in Walk Test
Mode. The first alarm on the Initiating
Circuit under test will ring associated
Notification Appliance Circuit(s) for 5
seconds. Zone Alarm LED will flash.
The second alarm on Initiating Circuit
under test will ring associated Notifica-
tion Appliance Circuit(s) for 1 second.
Zone Alarm LED will illuminate steadily.
A Trouble condition on Initiating Circuit
under test will sound piezo and light Zone
Trouble LED.
