Installation
INSTALLATION
2.1 Location & Mounting
Remove the printed circuit board, mounting hardware and keypad from the packaging inside the
panel box. The circuit board should not be mounted into the back of the cabinet, until all cables are
pulled into the cabinet and prepared for connection. Before mounting the cabinet, push the five
white nylon-mounting studs into the back of the cabinet. Select an installation site that is not easily
accessible to intruders. Leave at least 2" around the panel box to permit adequate ventilation and
heat dissipation. The installation site should be dry and close to an AC source, ground connection
and telephone line connection.
2.2 Earth Ground
Connect the zone and dialer ground terminals from the
control panel to the metallic enclosure and cold water pipe or
grounding rod as per local electrical codes.
For UL
installations, the metallic enclosure must be grounded to the
cold water pipe or grounding rod.
For maximum lightning protection use separate earth
grounds for the zone and dialer grounds (see figure 1)!
2.3 Power
2.3.1 AC Power
Use a 16.5V
AC
(50-60Hz) transformer with a MINIMUM 40VA
rating to provide sufficient AC power (
AUX
outputs = 500mA
each); RECOMMENDED 75VA rating to provide maximum
power output (
AUX
outputs = 1A each). Do not use any switch-
controlled outlets to power the transformer. UL listed systems
require the K12 model T16V40 or T16V75 transformer.
Do not connect the transformer or the back-up battery until all wiring is completed!
2.3.2 Back-up Battery
We recommend connecting a back-up battery to power the control
panel, in case of power loss. UL installations require the use of a back-
up battery. Use a 12V
DC
4Ah / 7Ah rechargeable acid/lead or gel cell
battery. Connect the back-up battery after applying the AC power.
When installing the battery, verify proper polarity, as reversed
connections will blow the battery fuse. Connect the "red" battery lead
to the positive battery terminal, and the "black" battery lead to the
negative battery terminal of the control panel. Use the Battery Charge
Current Jumper on the PCB to determine the charging current of the backup battery. With
the jumper ON, the charging current will be set at 350mA. With the jumper OFF, the
charging current will be set at 700mA.
2.3.3 Auxiliary Power Terminals
The 748 has two auxiliary outputs each of which can provide a maximum of 1A 12V
DC
with
a 75VA transformer and 500mA with a 40VA transformer (250mA 12V
DC
for 24hr standby on
UL installations). You can use the auxiliary power supply to power the motion detectors,
