Honeywell IdentIPoint Installation Instructions Manual page 30

HONEYWELL IDENTIPOINT™ INTELLIGENT SMARTCARD SYSTEM
In the above configuration, two IdentIPoint readers and one
IOM are inter-connected to control an IN/OUT door. While the
IdentIPoint readers authenticate users on both sides of the
door, the IOM releases the door lock upon the readers'
commands. A Request-to-Exit (REX) button is not required in
this setup.
Minimum Connections:
1. Connect the Ethernet/PoE cable to the RJ45 port of the
reader through the CAT5 pigtail. (Frame-GND connec-
tion to building GROUND Earth is recommended for
better electro-static discharge resilience.) See Fig.7.
2. If PoE switch is not used, connect a 12-24VDC power
supply to pins 1-2 (Power-IN - Power-GND) of port J9 of
the reader and pins 12V - GND (J1) of the IOM through
a common rail. This is the recommended power supply
configuration as it is necessary to provide a common
ground to all three devices. See section Wire the Read-
ers and IOM of Wiring the Readers and IOM topic for
details on power supply connections.
3. Connect the RS485-A, RS485-B and RS485-GND (pins
3, 4 and 5 on port J10 of the In-reader) to their corre-
sponding RS485 points on J14 of the IOM. See section
RS485 Communication and Termination Setting of Con-
nector and Switch Descriptions topic for details on
RS485 wiring and termination settings. Set the S1 DIP
switch on the In-reader and the IOM accordingly.
95-7767
4. Connect pin(s) NC/NO/RL0-C or RL1-C (J12/J13) of the
IOM to the door lock depending on the type (magnetic
lock or door strike) used and the safety codes to be fol-
lowed. Also connect a power line to the lock. Detailed
wiring for locks is shown in Wiring Other Devices topic.
5. Connect J6, J7, J8 or J9 of the IOM (SAI-n - SAI-n-
GND) to a door sensor with proper termination circuit as
described in section Supervisory Analog Input (SAI) ter-
mination circuit of Wiring Other Devices topic.
6. Make all other interconnections between the Out-reader
and IOM as shown in Fig. 23.
NOTE:
• The Out-reader must be installed on the secure side
of the door along with the IOM.
• For a single door controlled by two readers with IOM
the door sensor shall always be wired to SAI-3 of the
IOM.
• The RS485 ground signal is not necessary if the IOM
is powered by the IdentIPoint reader or if there is a
common ground available between the two units.
• The resistors need to be connected at proper
terminals as shown in the diagram.
• REX and Door Sense support only Normally Closed
and not Normally Open positions, i.e., REX is
detected when SAI switch is open, Door is sensed as
open when SAI switch is open.
