Low Voltage Wiring Notes
Low voltage wiring in the ControlKeeper T consists of
switch wiring and network wiring. Please refer to the
installation instructions with the ControlKeeper T for more
in-depth information on low voltage wiring.
Network Wiring Notes
The ControlKeeper T is designed to communicate with
other ControlKeeper network panels using a lighting control
RS-485 network for communications. This allows the panels
to share information and to be programmed from one
central location by a computer with the Keeper Enterprise
Software.
For best network performance, Belden 9841 cable
should be used. If the specified cable is not used
and communications problems occur that require
troubleshooting assistance, additional charges for support
may be assessed.
1. All low voltage wiring is Class 2.
2. All low voltage wiring must enter the cabinet from the
lower-left side of the enclosure or be piped through
the high voltage section in conduit using the special
knockouts reserved for this section.
3. All low voltage wiring must be run in separate conduit
from line voltage wiring.
4. Test all network wiring for shorts to AC ground before
connecting to the ControlKeeper T panel.
5. Leave all shields disconnected making certain that
shield is not exposed.
6. Panels and devices on the RS-485 lighting network
should be daisy-chained. Do not create a Star or
T-tapped configuration.
7. Total network length should not exceed 4000 feet.
8. Include a network repeater (RPTR) if network exceeds
32 panels or 4000 feet.
Low Voltage Dry Contact Switch Wiring
This section describes the wiring for dry contact closure
devices.
1. All low voltage wiring is Class 2 wiring.
2. All low voltage wiring must enter the cabinet from the
lower-left side of the enclosure or be piped through
the high voltage section in conduit using the special
knockouts reserved for this section.
3. All low voltage wiring must be run in separate conduit
from line voltage wiring.
4. Use 18 AWG twisted, unshielded wire for all low
voltage dry contact closure device wiring.
5. Maximum length for dry contact closure device wiring
is 1000 feet.
