Digital I/O adapters
For complete information on installing the digital input/output (I/O) adapters,
consult the manufacturer's documentation and the
Installation & setup for PCI
digital I/O cards
application note (A3DA1009-001).
You can install the digital I/O adapters in any vacant PCI slot in the computer. The
I/O adapters provide output (O/P) relays and optically isolated inputs (I/P) for the
Senstar 100 CU. You can install up to two digital I/O adapters per computer, and
the system supports the following four I/O adapters:
•
PCI-16REL card - 16 output relays (J2KT0101)
•
PCI-32REL-B card - 32 output relays (J2KT0201)
•
PCI-16ISO card - 16 optically isolated inputs (J2KT0301)
•
PCI-DIO32 card - 16 input and 16 output relays (J2KT0401)
The digital I/O cards are PCI 2.1 bus compliant Plug and Play adapters. The I/O
port addresses and IRQs are assigned automatically by the computer’s BIOS.
However, the Senstar 100 software does not require an interrupt to access the I/O
cards. There are no DIP switches or jumper settings required, with the exception
of the PCI-32REL-B card. The PCI-32REL-B card includes relay access jumpers,
which allow the user to access one or both sides of each relay, and to tie the relay
commons to ground, +5 or +12 VDC.
Figure 2-10 Digital input output cards
illustrates the four digital I/O cards.
The Senstar 100 system supports ISA slot digital I/O adapters for use in older
model computers. ISA version digital I/O adapter cards are available from
Senstar-Stellar (at the time of this publication).
Output relay card kits
The O/P relay cards provide either 16 or 32 discrete relays for the Senstar 100 to
drive or control auxiliary security devices such as sirens, lights, door locks, LED
panels, etc.
The default setting for the relays is normally open (OFF), and OFF is the default
drive state for the output points in the site database. This setting can be changed,
on a point per point basis, in the site database using the Site Creation utility.
