INSTALLATION
7-1 INTRODUCTION
This chapter provides information necessary to install the PE-
GAsys system. Installation consists of installing a complete sys-
tem. The procedures in this chapter should be accomplished
by technicians familiar with fire alarm system installation and
the requirements of relevant NFPA regulations.
7-2 MATERIALS REQUIRED FOR INSTALLATION
The materials listed below are not supplied with the system, but
are required for installation.
• No. 10 or 1/4 inch Mounting Hardware
• Electrical Conduit for AC Input Power
• 4-inch Electrical Junction Boxes (as required)
• Wire-Nuts and Crimp-On Terminals (as required)
• Ground Strap (for use when handling printed circuit boards
7-3 INSTALLATION PROCEDURE FOR CENTRAL
CONTROL PANEL
The PEGAsys Central Control Panel enclosure is 28 inches high
x 18 inches wide x 5½ inches deep. It is designed to be surface
or semi-flush mounted using No. 10 or ¼ inch hardware. The
type of hardware to be used is at the discretion of the installer
but must be in accordance with good electrical and safety prac-
tices.
Figure 7-1 shows the enclosure’s mounting hole layout. The
lower set of mounting holes should typically be 44 inches from
the floor in order that the display panel is at a convenient view-
ing height.
To facilitate mounting the enclosure to its wall position, remove
the enclosure’s front door. Be sure to disconnect the ground
wire before removing the door.
To remove the front door, open the door approximately 90º from
its closed position and lift it up enough to allow the door’s hinge
pins to clear their mating hinge sockets located on the left side
of the Central Control Panel.
Place the mounting screws in to the top two holes in the wall.
Leave approximately 1/4” of both screws exposed. Carefully
place the two key holes over the screws in the wall. Ensure the
enclosure has its door hinge sockets located to the left as you
face the enclosure. Allow the enclosure to gently come to rest
on the screws. Tighten the screws.
Figure 7-1. CCP Installation Drawing
With the enclosure held by the top two screws place the bottom
two mounting screws in place. Tighten the screws. Reinstall the
enclosure door at this time. Care must be taken when installing
the door to ensure that the hinge pins are lined up correctly.
7-4 INSTALLATION PROCEDURE FOR
EXPANSION ENCLOSURES
The expansion enclosure (P/N 76-100000-505) uses a back
plate installed in the enclosure to meet various system compo-
nent requirements. The expansion enclosure maintains the
same outside dimensions as the main system enclosure. There
are three versions of the backplate:
• An I/O module cardcage with mounting provisions for up to
4 power supplies
• Mounting provisions for up to eight power supplies
• Two motherboard cardcages for mounting up to 16 I/O mod-
ules in the expansion enclosure.
The optional I/O motherboard and I/O modules must be installed
prior to the system being powered up. The I/O bus (communi-
cations) and 24 VDC power are attached to connectors located
on the I/O Motherboard.
NOTE: The I/O Bus (RS-485) wiring must be enclosed in
raceway from the main enclosure for a maximum run
of 20 feet, with expansion enclosures located in the
same room as the main enclosure.
Figure 7-2, shows the expansion backplate which provides
mounting for 4 power supplies and one I/O motherboard. Fig-
