Procedures

General Procedures

The only item that requires regular testing and maintenance is the 7AH backup battery (not available for

RAK3). It is recommended that the battery in each unit is tested at least once a year by disconnecting its

external power supply and checking that the unit continues to operate normally for the period of time

specified in the Service Contract.

This equipment is to be installed indoors only (except readers that specify otherwise). Impaired operation

will result if the equipment is subject to excessive humidity or temperature, or in the event of prolonged

power loss.

LED Operation

This section explains the meaning of each LED on the M2150 boards, which may be useful when testing

system operation or during fault-finding.

LEDs on the 2DBC

LED2/1 (RDR 1/2) – Illuminated when the reader is connected properly.

LED3 (DC COMMS) – Illuminated when an external door or alarms controller is connected.

LED 6 (CLB) – Flashes to indicate HOST COMMS B (COM B) port usage. 2 flashes = port in use; 5

flashes = port not used (RS232, NIC1 or NIC2 port set to Bidirectional Comms port usage).

LED 7 (CLA) – Flashes to indicate HOST COMMS A (COM A) port usage. 1 flash = port in use; 5 flashes =

port not used (RS232, NIC1 or NIC2 port set to Normal Comms port usage).

LED8/5/4 (RS232/NIC1/NIC2) – Indicates the Port Usage configuration setting for COM ports C, D and E

(as described in the 2DBC Installation Instructions). 1 flash = Normal Comms (indicates primary port when

two NIC4s fitted); 2 flashes = Bidirectional Comms; 3 flashes = Fall-Back Comms; 4 flashes = Serial

Device; 5 flashes = port off (another port has been set to the same setting); 6 flashes = Secondary port

when two NIC4s fitted.

LED9 (OK) – When the 2DBC is functioning correctly, this should flash once per second.

LED10 (3V) – Illuminated when the on-board 3Vdc supply is operating.

LED11 (5V) – Illuminated when the on-board 5Vdc supply is operating.
