6.17 Sunblind Control Module
Figure 35. Sunblind Control Module
The Sunblind Control Module is a passive device on the teleCARE IP room bus. It is used in
combination with the NIPH3-A7A and NIPH3-AES handsets, in combination with the bedside module
NIBM2 and the medical rail socket NIMS2, to raise or lower sunblinds.
The sunblind control module includes two heavy duty relays, with normally open contacts, to control
sunblind up and down motors. The maximum current through the relay contacts is 5 Amps. The
sunblind control module prevents the up and down activation of the sunblind motor at the same time.
The sunblind control module provides galvanic isolation between the teleCARE system and the
sunblind motor electrical supply.
The sunblind control module must be connected to the same room bus as the bedside module (or
medical rail socket) and handset which require sunblind control capability.
The sunblind control module can be connected to one or two room buses from the same room
controller. It only responds to the room bus addresses 0 to 3 of the connected room buses. Numerous
sunblind control modules can be combined to control one sunblind motor.
On the circuit board of the sunblind control module there are two green LEDs which continuously
flash when the module is correctly connected to the room bus and ready for use. Also on the circuit
board there are two red LEDs, one for each relay. The red LED comes on when the corresponding
sunblind up or down button on the handset is pressed.
The sunblind control module has two DIP switches which are used to prevent the sunblind control
module from responding to specific room bus addresses.
The Sunblind Control Module is mounted on a 1-1/2” DIN rail, which must be permanently mounted
to a wall. It must not be within reach or intentional access of a resident (e.g., above a ceiling tile), or it
can be mounted within a separate electrical equipment enclosure.
