SPECIAL NOTES FOR U.L. INSTALLATIONS
The 7720PLUS Subscriber Unit can be used in systems Listed by Underwriter’s Laboratories for Grade A
and Grade B Central Station Mercantile Burglary. The following additional requirements must be observed
for the installation of subscriber remote equipment in such systems:
1.
Installation must be in accordance with the National Electrical Code, UL611 and UL681.
2.
The 7720PLUS is intended to be connected to dry contact and voltage trigger outputs of a Listed compatible
control unit.
3.
The 7720PLUS must be programmed as follows:
a) This product is not Listed for Fire Alarm Service. Therefore, zones should not be programmed as pulsed
(programming questions 9a, 10a, 11a, 12a).
b) Delayed reporting should be programmed as 00 (programming questions 9b, 10b, 11b, 12b).
c)
Restoral reporting must not be disabled (programming questions 18, 19, 20, 21).
d) The Telco channel must be enabled. Do not enter 0 (programming question 23).
e)
A tamper zone must be enabled (programming question 24). The tamper switch shall be enabled and
mapped to a 7720PLUS zone. (Tamper is automatically configured in ECP configured radios.)
f)
The High Security Antenna Test option must be programmed as YES (programming question 25). The
default is once every 135 seconds.
g) AC Loss Reporting must be programmed as YES (programming question 26).
h) The Fault Relay On option must be programmed as YES (programming question 27).
i)
The Fault Relay Latched option must be programmed as YES (programming question 28).
4.
FOR GRADE A CENTRAL STATION INSTALLATIONS: A UL Listed communicator must monitor the
radio fault output (terminals 11 & 12) of the 7720PLUS. A No. 659EN Telco Line Monitor’s output should be
connected to an input zone of the 7720PLUS unit. The 659EN shall be inside the control enclosure. Premises
openings and closings should be sent via the communicator. The fault relay (question 26) shall be
programmed as fail-safe (fault relay ON) and jumper J1 shall be set in “A” position (normally closed). In
addition, the installation must meet the requirements defined for GRADE B CENTRAL STATION
INSTALLATIONS defined below.
5.
FOR GRADE B CENTRAL STATION INSTALLATIONS: All wiring between the 7720PLUS and the
Listed control panel must be enclosed in rigid conduit (outside walls) or flexible conduit (inside walls or above
ceilings). The control unit shall be a Listed Grade A Local Burglar Alarm Unit/Police Connect Unit.
6.
FOR POLICE STATION CONNECTED INSTALLATIONS: Same requirements as for GRADE A
CENTRAL STATION INSTALLATIONS defined above, except that the control panel must be Listed for
GRADE A POLICE CONNECT, and premises openings and closings do not need to be sent via the
communicator.
7.
All wiring not run in conduit shall be contained within the same room as the 7720PLUS.
