Signal Inputs and Outputs
To / From Access Control System
Inputs
Signal inputs from outside systems
are wired into the SU3500’s I/O control
board. There are two types of input
signals, momentary dry contacts (MDC)
and sustained dry contacts (SDC). All
input signals must be normally open
(N.O.), voltage-free, dry contacts, with
the exception of the fire alarm input,
which can be configured (via jumper
on the I/O control board) to accept
either a normally open or normally
closed (N.C.) sustained contact. MDC’s
must be at least 100ms in duration to
register. While the SU3500 can accept
signals up to 2 seconds in duration,
the suggested MDC input duration
is 1 second or less to support rapid
throughput in high-volume applications.
Factory default fire alarm jumper setting
is normally open (N.O.).
Outputs
Signal outputs are available from the
SU3500’s I/O control board. Outputs
are normally open, voltage-free,
momentary dry contacts. The output
signal length is 300ms in duration.
Inability to Provide Specified Inputs
If the access system cannot provide the
specified MDC’s, isolation relays should
be used. NEVER connect signal lines
containing voltage directly to the I/O
control board.
