Installation

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 ECS-Series control for the first time.
3.1

Environmental Specifications

It is important to protect the ECS 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 0°C-49°C (32°F-120°F) or humidity outside the range of
10%-93% at 30°C (86°F) noncondensing.

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 0 Ω.
•
• 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. See Figure 3-1 and Figure 3-2 for an examples.
