ALARM CONNECTION
Superterm CIC1800 / CICP1400UL 38
ALARM CONNECTION
The Superterm has a total of 24 supervised alarm
inputs. Sixteen alarm inputs are located on the
DR1 through DR8 terminal strips, and are used for
Request-to-Exit and Door Status sensor functions
(see pages 18 and 19).
An additional eight auxiliary alarm inputs are
located on the ALARM terminal strip located on
the upper left-hand comer of the Superterm circuit
board (see Figures 25 and 26). These auxiliary
alarm inputs may be used for dry contact type
inputs (unsupervised) or supervised alarms.
Supervised Alarms
Supervised alarms provide monitoring of alarm
inputs for fault or tamper conditions. Three
additional alarm states may be detected by
installing two-1K Ohm) resistors near the alarm
contacts.
In addition to the standard Normal and Abnormal
alarm conditions, the supervised alarms report
Open, Closed, and Fault conditions.

An Open condition is the result of a cut wire.

A Closed condition is the result of shorting the
alarm contacts together.

A Fault condition is the result of grounding
one of the alarm wires.
Configuring an Alarm in the Supervised
Condition
1) Use two 1K Ohm, 1/4W, ±5% carbon film
resistors per alarm.
2) Install R 1 in parallel with the alarm contacts
(see Figure 26).
3) Install R2 in series with the alarm input
conductor.
NOTE: For maximum protection, install the
resistors close to the alarm contacts and embed
them in epoxy.
Table 25 lists the ALARM terminal strip pin
numbers and the respective signals.

Alarm Cable Requirements
Connecting alarm sensors to the Superterm board
requires 22 AWG, stranded, shielded, cables with
drain wires.
NOTE: DO NOT use twisted pair wires.
CAUTION
Keep all drain and cable shield wires between
the Superterm and Keypads short. Connect
drain and cable shield wires to the ground posts
located on both sides of Superterm cabinet. DO
NOT ground drain wires and cable shields at
any other point.
Tamper Switch
The Superterm cabinet has a built-in tamper
switch. The tamper switch is factory wired and
requires no adjustment.
NOTE: When the Tamper Switch closes, all LEDs
will extinguish (except AC on LBD1). Refer to
page 74, LED Diagnostics, for more specific
information.
