Control Station Device (CSD) Link Wiring
• Use low-voltage PELV (Class 2: USA) wiring to
daisy-chain Wallstations to the Processor Panel.
• Make connections inside the wallbox or in a
switch/junction box with a maximum wire length of
8 feet (2.5m) from the link to the Wallstation.
• Two #12 AWG (2.5mm
2
) conductors for common
(terminal 1) and 24 V (terminal 2). These will not
fit in terminals. Connect as shown.
• One shielded, twisted pair #18 AWG (1.0mm
2
) for
data link (terminals 3 and 4).
• Connect Drain/Shield as shown. Do not connect to
Ground (Earth) or Wallstation. Connect the bare
drain wires and cut off the outside shield.
Note: Some Wallstations have a “D” terminal for
Drain. The Drain/Shield wire may be connected to
this terminal.

Specifications
• No power pack required to power one occupant
sensor (see next page for wiring details).
• Power Supply Output (Terminal B):
- 24 V , 50 mA maximum.
- An auxiliary power supply must be used if the
maximum current limit is exceeded or more than
one occupant sensor is connected to the
wallstation (see next page for wiring details)
• Occupant Sensor Signal Input (Terminal A):
- Input must be dry contact closure or solid-state
output from the Occupant Sensor:
Dry Contact Closure from Occupant Sensor:
- Referenced to Common (Terminal C) or
Power Supply (Terminal B: 24 V ).
- Rated Voltage: 20 V when open.
- Rated Current: 0.5 mA when closed.
Solid-State Output from Occupant Sensor:
- Open collector (NPN or PNP) or
active-high/active-low.
- When open collector NPN or active-low
referenced to Common (Terminal C),
on-state voltage at Terminal A must be
less than 6 V (at 0.3 mA).
- When open collector PNP or active-high
referenced to Power Supply (Terminal B),
on-state voltage at Terminal A must be
greater than 18 V (at 0.3 mA).
- Off-state leakage current less than ±60 uA.
- Outputs must stay in the closed or open states
for at least 40 msec in order to be recognized by
the Wallstation.
Occupant Sensor Connection
Caution! A seeTouch Wallstation that is
supplying power to an occupant sensor
counts as 2 Control Station Devices
(CSDs) on the CSD link.
• Wallstation is miswire protected up to 36 V .
• Wallstation supplies power for and receives a
control signal back from one occupant sensor.
• See next page for wiring details.
