6.6.2 NIMS2 Room Bus Address Setting
The room bus address of the medical rail socket is selected using the DIP switch on the top side of the
printed circuit board. For details of the DIP switch settings see 6.4.10, Dip Switch Settings on page 71.

6.6.3 Light Switching Relay Maximum Load and Surge Damping Diode
The medical rail socket NIMS2 includes 2 light switching circuits with normally open (N/O) contacts.
The contacts are potential free and galvanically isolated. Each circuit is suitable for switching a bi-
stable 24 volt DC external relay. The maximum switching current for each relay must not exceed 0.3A
at maximum 30Vdc.

WARNING:
• The equipment that is connected to this interface is not considered to be part pf the system
configuration unless the equipment complies with ANSI/UL 2560 standard for Emergency Call
Systems for Assisted Living and Independent Living Facilities.
• Do not connect the bed light circuitry directly to the L1 and L2 switch contacts on the NIMS2.
• The Light Switching Power Supply and Relay must be UL recognized components.
• The maximum switching current for the L1 and L2 contact on the NIMS2 must not exceed 03.A at
30Vdc.
• A diode (1N4004 or equivalent) must be connected across the coil of the bed light switching relay
to prevent surges caused by the relay coil.
