Removing The Radio% Cover
Remove
the cover
by inserting
a

screwdriver into the 4 removal points
at the bottom of the unit and gently
o r
releasing the locking tabs from the
cover slots as shown.

Refer to the diagram below when setting jumpers.
If using zone input connections, set the J2 jumper so that zone 1 & 2 inputs are
activated either with a ground or with a positive voltage, whichever is required.
If the trigger level is set for positive voltage, +4.5 to +14.2 volts must be applied to
zones 1 & 2 to trigger an alarm. If the zone is connected to a normally high voitage
trigger (i.e. goes iow on alarm), invert this zone when programming (programming
questions 12 & 13).
if ground is selected, zones 1 & 2 are internality puiied up to 5 voits through a 10k ohm
resistor. This voitage shouid normaiiy be puiied down (ciosed contact to ground) and
released for aiarrn (opening the contact). If
a
normaiiy open contact is being used, invert
this zone when programming (programming questions 12 & 13).
The radio fauit output reiay may be programmed for either FAIL-SAFE mode (reiay
aiways energized) or LOW CURRENT mode (reiay normaily de-energized) by seiecting
Yes or No to programming question 26: FLT REL ON (Y/N). In addition, the reiay can be
set for either N.O. or N.C. operation (in either fail-safe or low current modes) using the
J1 jumper.
When faii-safe mode is seiected, the relay wili change states (and trigger a dialer, if
connected) in the event of power ioss. Note that fail-safe mode increases the standby
current by about 10mA, which results in lower battery backup time (about 15Yo)in the
event of power ioss. Set the J1 jumper to position A or position B, as foiiows:

Use the 7720P position when
programming with a 7720P programming
tool. The ECP function is not supported
by the 7720V2.
This output connector provides for two
voitage outputs which are deriied from the
batte~ through 1K resistors which are
suitable for use with zones 3 and 4 when a
dry contact driving device is being used.
Connection to this output maybe made
using the optionai Ademco cable, part
number 7720TVC.
