As part of your Synergis™ Cloud Link installation, you might need to include a Mercury LP1502 intelligent controller.
IMPORTANT: LP controllers include a Micro USB port. This connection is not
to be used if UL/ULC listed access control system compliance is required and is to
be maintained.
The following diagram demonstrates how to connect the controller.
A | Reader connections | TB8: Door 1 Reader NOTE: The wire colors in the illustration refer
to "pigtail" HID readers; the information in parentheses refers
to "terminal block" HID readers. Connect the drain wire of the
shielded cable to the GND contact of the interface module's
reader port. For OSDP daisy-chained readers, do not connect the
drain wire to the last reader.
|
B | Reader connections | TB9: Door 2 Reader NOTE: The wire colors in the illustration refer
to "pigtail" HID readers; the information in parentheses refers
to "terminal block" HID readers. Connect the drain wire of the
shielded cable to the GND contact of the interface module's
reader port. For OSDP daisy-chained readers, do not connect the
drain wire to the last reader.
|
C | Power In | Connect + to VIN (observe polarity). Connect - to GND. Use 20 AWG wires minimum. |
D | Ethernet cable | Connect to the Synergis Cloud Link directly or through the network infrastructure. |
E | RS-485 bus | RS-485 bus connection to other Mercury modules. |
F | Reader power | 12V = 12 V dc at readers, PASS = voltage “passed through” to
readers. IMPORTANT:
For UL294 compliant Synergis™ installations,
always install the jumper in the PT
position.
|
G | 4 x Form-C LP1502: NO: 5A, NC: 3A, inductive @30 V dc, 0.6 PF |
|
H | Resistors | For OSDP integrations, prevent readers from misinterpreting noise
as data on a non-driven RS-485 line by installing a 1k ohm pull-down
resistor from D0 to GND on both TB8 and TB9. For wiring distances over 10 meters, install a 120 ohm termination resistor between D0 and D1, as well as between A (-) and B (+) on the RS-485 bus of the last connected reader. To find out whether you need to add a 1K ohm pull-down resistor between D0 and GND, see KBA-78953. |
