Wiring; Attaching The Control Panel To The Bracket - Visonic Powermax Installation Instructions Manual

The two upper mounting holes are intended for regular
attachment to the wall with screws and anchors. The lower
mounting hole, however, accommodates a combined "ring
and cam" piece connected to the bottom leg of the bracket
by 3 breakable plastic joints.
A special plastic washer supplied with the bracket must be
inserted into the ring to complete the lower mounting hole.
With the washer in place, a third screw can be used to
secure the bottom leg of the bracket to the wall.
Once the control panel is mounted in place, the cam
enters a slot in the control panel's rear part and maintains
the built in tamper switch pressed. Separating the control
panel from the bracket will start a tamper alarm. Forced
removal of the entire assembly off the wall will also start a
tamper alarm, because the joints of the ring and cam
piece to the bracket will break off, leaving the ring and
cam attached to the wall.
C. Attaching the Bracket to the Wall
Choose a concealed place, yet easily accessible to
prospective users of the alarm system. Make sure that an
uninterrupted AC power outlet and a telephone line socket
are available near the installation spot.
Use the bracket as a template to mark the drilling points.
Drill the holes and attach the bracket to the wall with 3
screw. Be sure to insert the special plastic washer into the
ring in the bottom hole, as shown in Figure 8.

3.5 Wiring

All terminals and connectors are accessible within the
opening at the back of the PowerMax (see Figure 9). All
screw terminal blocks (except for "EARTH") can be pulled
out, wired appropriately and plugged back in.
WARNING! When plugging terminals back
into place, be sure to align them carefully
with the pins on the PCB. Misaligned or
reverse insertion of terminals may damage
internal PowerMax circuits!

The telephone-type RJ-11 connectors are also easy to
deal with, because of their quick attach/detach capability.
IMPORTANT! The earth ground terminal must be
connected to a good earth ground to allow effective
protection against lightning transients.
Following are two examples of good earth connections:
Cold-water metal pipe: Connect the earth wire to the
pipe, using a non-corrosive metal strap (preferably
copper), firmly secured to the pipe.
AC Power outlet ground: This ground is available in
3-prong, 120 VAC outlets. Test the validity of the ground
terminal with a 3-wire circuit tester that has neon lamp
indicators (UL Listed Ideal Model 61-035 or equivalent,
available from electrical supply stores).

For telephone type connectors, you will need these items:
• A length of 6-lead, color coded modular cable.
• An length of 8-lead, color coded modular cable.
• Two 6-position and one 8-position RJ-11 male connec-
tors, to terminate the cables at the PowerMax end.
• A crimping tool for 6-position and 8-position RJ-11 plugs.
