teleCARE IP
6.3 Bedside Module (NIBM2)
The Bedside Module (NIBM2) is designed for use in the teleCARE IP system. It is an active switch
module connected to room bus addresses 0, 1, 2 or 3. The address is set by an on-board DIP switch.
The room bus includes the 5.5 Vdc power supply for the NIBM2.
The NIBM2 supports speech and entertainment in teleCARE IP.

The NIBM2 has three function buttons (red, green and yellow). The red button is for call. The functions
of the yellow and green buttons depend on the configuration. Each button has an LED which
illuminates to indicate the activated condition and permanently emits a low intensity light for location
and identification in the dark.
The NIBM2 includes a Safe Release socket for connecting a handset. A red dot on the cover plate
indicates the location of the Safe Release socket. See “Connecting and disconnecting the Safe
Release Plug” on page 108
.
The NIBM2 has two bidirectional solid state relays for control of two light switching relays. A four-pin
connector facilitates two sets of normally open contacts for control of two light switching relays.
The NIBM2 supports the following external inputs and outputs:
• Control outputs for 2 light switching relays
• Stereo TV audio input
• External call input with an open-collector LED output
• NISP speech module
The NIBM2 has on-board diagnostics. When a room bus failure is detected all the button LEDs will
flash intermittently.
The NIBM requires a single switch module back-plate. Alternatively, a spacer with installation kit is
available for surface mounting the NIBM. A double or triple backplate is required when the NIBM is
combined with a speech module.
