Supervised Alarm / Relay / Power Expansion Unit 12
Installation Preparation
First, select a mounting location within a secure, limited access
area (see Figure 5). Note the type of wall construction that the
enclosure will be secured to.
•
Determine that adequate space is available for mounting
the Expansion Unit cabinet on a wall with no interference
from wires, pipes, or other obstructions.
•
Proper installation of the Expansion Unit cabinet requires
an area of free space measuring at least:
23 inches high (584mm)
X
20 inches wide (508mm)
X
4.0 inches deep (101.6mm)
•
Confirm that adequate free space exists on both sides of
the Expansion Unit cabinet for cabling conduit entering
and exiting the cabinet.
•
Determine the directions of the cabling conduit exiting the
Expansion Unit cabinet. Confirm sufficient access to ceil-
ings and/or walls before fitting the conduit lengths.
•
Knockouts at the back of the unit may be used for "hidden
wiring" installations.
NOTE:
All Expansion Unit signal wiring and accessory
power circuits are certified as power limited. The use of
conduit is optional for these circuits.
