DOOR CONNECTIONS
Superterm CIC1800 / CICP1400UL 25
Request-to-Exit (Bypass) Sensor Connection
Request-to-Exit sensors (also known as Bypass
sensors) work in conjunction with Door Status
Sensors to provide complete facility entry and exit
control. The Request-to-Exit sensor input connects
to the same Superterm terminal strip (DR1 through
DR8) that the associated Door Status Sensor
connects to (see Figure 14).
Table 14 lists the connections between the DR1
through DR8 terminal strips and the associated
Request-to-Exit sensor.

NOTE:
Request-to-Exit sensor connections to the
Superterm are not sensitive to polarity.
Request-to-Exit Sensor Cable Requirements
Request-to-Exit sensors require a 22AWG, 2-
conductor, stranded, shielded, cable with drain wire
between the Superterm and the particular unit (see
Figure 14).
NOTE: DO NOT use twisted pair cables.
Table 15 lists the cable gauge-vs-length
requirements for proper operation of the Superterm
and the Request-to-Exit sensor.
