PART 1. SITE REQUIREMENTS
When planning the installation of the DCS COMPA C T
, choose a site that meets the following requirements:
Select a location for the key service unit (KSU) that has enough space for easy installation and
has adequate lighting (see Figure 1–1).
Select a location that will minimize cable lengths. See the Cable Requirements table below.
The equipment should not be exposed to direct sunlight, corrosive fumes, dust, constant
vibration or strong magnetic fields such as those generated by motors and copy machines.
A direct commercial AC power outlet is required. Do not use extension cords.
P r e f e r a b l y, a dedicated circuit should be used to minimize the risk of other electrical equipment
being connected that could adversely affect system operation.
Ensure that all wires and cable going to and coming from the KSU are properly routed. Do not
cross fluorescent lights or run parallel with AC wires.
The equipment must be located in an environment that will maintain a temperature range of
– – and a humidity range of 10%–90% non-condensing.
Allow at least 6" clearance on both sides and 6" clearance on top of the KSU to ensure proper
v e n t i l a t i o n .
Do not install in close proximity to a fire sprinkler head or other sources of water.
Meeting these requirements will help to ensure proper performance and greater life expectancy of
the system.
* This is the maximum distance a door phone can be from the DPIM. The DPIM can be a maximum
of 900 cable feet from the KSU.
