Table of Contents

This section of the manual is intended to help you plan your tasks to complete the installation. Please read this section thoroughly, especially

if you are installing a EVS Series control panel for the first time.

3.1 Environmental Specifications

It is important to protect the EVS panel from water. To prevent water damage, the following precautions should be followed when installing

the units:

•

Mount in indoor, dry environments only.

•

Do not mount directly on exterior walls, especially masonry walls (condensation).

•

Do not mount directly on exterior walls below grade (condensation).

•

Protect from plumbing leaks.

•

Protect from splash caused by sprinkler system inspection ports.

•

Do not mount in areas with humidity-generating equipment (such as dryers, production machinery).

When selecting a location to mount the control panel, the unit should be mounted where it will NOT be exposed to temperatures outside the

range of 32°F-120°F (0°C-49°C) or humidity outside the range of 10%-93% at 86°F (30°C) non-condensing.

3.2 Wiring Specifications

Induced noise (transfer of electrical energy from one wire to another) can interfere with telephone communication or cause false alarms. To

avoid induced noise, follow these guidelines:

•

Isolate input wiring from high current output and power wiring. Do not pull one multi-conductor cable for the entire panel. Instead,

separate the wiring as follows:

•

Do not pull wires from different groups through the same conduit. If you must run them together, do so for as short a distance as

possible or use shielded cable. Connect the shield to earth ground at the panel. You must route high and low voltages separately.

•

Ground fault and wire to wire short impedance to any terminal is 0Ω.

•

Route the wiring around the inside perimeter of the cabinet. It should not cross the circuit board where it could induce noise into the

sensitive microelectronics or pick up unwanted RF noise from the high speed circuits. Refer to the FACP manual for wire routing

examples.

•

High frequency noise, such as that produced by the inductive reactance of a speaker or bell, can also be reduced by running the wire

through ferrite shield beads or by wrapping it around a ferrite toroid.

NOTE: All circuits are power limited except the battery and AC cabling. Maintain 0.25 inch spacing between high and low voltage circuits and

between power-limited and non-power limited circuits.

3.3 Cabinet Mounting

Refer to the appropriate FACP manual for cabinet mounting instructions and wire routing examples. See Section 1.4 for a list of related doc-

umentation.
