UL Power Limited Wiring Requirements 3 Installation Procedure
The PDRP-1002 PN 51135:A 03/11/99 15
3 Installation Procedure
General
Carefully unpack the system and check for shipping damage. Mount the cabinet in a
clean dry, vibration-free area in which extreme temperatures are not encountered. The
location should be readily accessible with sufficient room for easy installation and
maintenance. Locate the top of the cabinet approximately five feet above the floor with
the hinge mounting on the left. Determine the number of conductors required for the
devices to be employed. Pull required conductors into the box through the knockout
provided. All wiring should be in accordance with the National and/or Local codes for
fire alarm systems.
UL Power Limited Wiring Requirements
Power limited and non-power limited circuit wiring must remain separated in the
cabinet. All power limited circuit wiring must remain at least 0.25 in (6.35 mm) away
from any non-power limited circuit wiring. Furthermore, all power limited circuit
wiring and non-power limited circuit wiring must enter and exit the cabinet through
different knockouts and/or conduits. A typical wiring diagram for the PDRP-1002/
PDRP-1002E is shown below.
