RELAY CONNECTIONS
Superterm CIC1800 / CICP1400UL 30
LOCAL Power Connection
In LOCAL power mode, a single, external power
supply (28VDC or 28VAC max.) is mounted
outside of and adjacent to the Superterm cabinet.
This supply provides power to a maximum of eight
Superterm door strike relays through the STKPWR
terminal strip located on the lower edge of the
Superterm circuit board (see Figure 17).
Strike power is routed through the Superterm
circuit board to the individual relay connectors,
thus eliminating the need for separate power
supplies at each door.

The STK- input (STKPWR - Pin 4) is routed to
the COMMON (C) relay connection (RLY #X
- Pin 2).

The STK+ input (STKPWR - Pin 3) is routed
through the DIS pins (1 and 2) to the Normally
Open (NO, RLY #X - Pin 1) or the Normally
Closed (NC, RLY #X - Pin 3), depending on
the state of the relay.
A Normally Closed (NC) emergency switch may
be used in conjunction with the Local power mode
to disconnect the strike power upon an emergency
situation.
NOTE: Operating a door strike relay in the
LOCAL mode requires setting two jumpers per
relay. Refer to page 72 for specific information
about setting the door strike jumpers.
All door strike relays connected in the LOCAL
power configuration operate from the same power
source and must have the same voltage rating.
All strike relay circuits (odd numbered relays) are
individually fuse protected in both the LOCAL or
the REMOTE configuration.
If an emergency sensor is not used, install a jumper
between Pin 1 (DIS) and Pin 2 (DIS) on the
STKPWR terminal strip.
Table 16 lists the connections between the
STKPWR terminal strip and the external power
supply (see Figure 17).

Power Supply

Emergency Sensor Connection
An external emergency sensor may be used to
disconnect the LOCAL strike power supply if an
emergency condition is detected.
The emergency sensor is placed in series with the
STK+ signal by connecting it between Pin 1 and
Pin 2 of the STKPWR terminal strip (see Figure
18).
NOTES: The emergency sensor must be a
Normally Closed (NC) switch and the strike relays
must be wired in a Normally Closed (NC)
configuration (refer to page 26, LOCAL Power
Door Strike Connection).
If an emergency sensor is not used, place a jumper
between Pin 1 and Pin 2 on the STKPWR terminal
strip (see Figure 17).
