4.2 Installing a 635-DRM Board (Dual Reader Module)
If you are not installing a DRM board, skip this section.
If you are installing the 635-DRM for Remote Door operation, see the section for 635-DSI Remote Door installation.
635-DRM - BOARD FEATURES
For reference, this section describes the components and features of the 635-DRM. See Appendix for 600-model hardware.
Board Reset Switch (SW1):
for resetting the board to initialize the Jumpers and Dipswitch settings, or reset operation.
Binary dipswitch (SW2):
for assigning the Board ID (before installing), as well as Remote Door Option-B.
Reader Supervision (R45/R8) SIP sockets:
allow installer to change the supervision resistor value as desired
(factory default = 4.7k ohm Resistors). Matching values must be set in the SG software Reader Properties screen.)
Supports Dry Relay contacts
(normal operation default)
vs. Wet Relay contacts
(wet relay operation)
Pwr Input (J11-LPR) & Jumpers (J15/J16/J17/J18) for configuring wet relay operation.
(Dry Relay is the factory default)
Power Input (J11)
for connection to controller power harness.
Power LED (D12)
indicates board is connected to the power harness and the power is on (solid/on).
I2C Data Input (J13)
for ribbon cable connection to the CPU Board I2C Data Buss.
Remote Door RS-485 Input (J14)
used with the 635-DSI 485 Channel (see 635-DSI Section for wiring and topology).
Reader, REX, Door Connectors (J6/J9):
for wiring Readers, REX, and Door hardware.
Relay-1 & Relay-2 Connectors (J8/J7; J5/J4):
for wiring Locks (Relay-1) & addit. hardware (Relay-2)
(4 SPDT Form-C Relays provide 1.5 A max. output). Supports wiring all relays as Normally Open and Normally Closed(NC)
LEDs for Lock Relay-1 and Relay-2 (D7/D6; D2/D1)
indicate when the relay is engaged (solid/on) or disengaged (off).
