(J2)
Zone
Inputs
Activate
on
High
or Low: If using zone input oonneotions,
set the J2 jumper so that zone 1 & 2 inputs
are activated either with a ground or with a
positive voftage, whiohever is required.
if the trigger level is set for positive
voftage, +4.5 to +12 vofts must be applied
to zones 1 & 2 to trigger an alarm. If the
zone is connected to a normally high
voltage trigger (i.e. goes low on alarm),
invert
this
zone when
programming
(questions 8 & 9).
if ground is selected, zones 1 & 2 are
internally pulled up to 5 volts through a 10k
ohm resistor. This vottage should normally
be pulled down (ofosed oontact to ground)
and released
for alarm
(opening
the
contact). If a normally open contact is
being
used,
invert
this
zone
when
~miw
(ques~s
8 & 9).

Fault
Output
Select:
The radio
fault output relay may be programmed for
either FAIL-SAFE
mode (reiay afways
energized) or LOW CURRENT mode (relay
normally de-energized) by seleoting Yes or
Nob
programming question 13: FLT REL
ON (Y/N). In addiin,
the relay can be set
for either N.O. or N.C. operation (in either
fail-safe or fow current modes) using the JI
jumper. When fail-safe mode is selected,
the relay will change states (and trigger a
d=ier, if oonnected) in tie event of pcrwer
ioss. Note that fail-safe mode increases
the standby ourmt by about 10mA, which
results in lower batterv bsdam time (about
15%) in the event of ~wer loss. Set-the J1
jumper
to position
A or position
B,
according to the following tabie:

Select:
If the ACP or
ECP interface will be used, then set the J3
jumper as indicated for the desired mode.
When
connected
to
the
7720P
Programming Tool, the jumper should be
set in the ECP mode.
