6.6.4 External Call Contact with Call LED Output
The external call connection allows an external normally open third-party contact to activate a
teleCARE call in parallel to the red button of the bedside module.
The 4-pole connector provides SWITCH and GND terminals for connection to a normally open contact
of an external switching device. These terminals provide 5.5Vdc at 0.6mA, for monitoring the external
device contact.
The 4-pole connector also provides a +5.5V output and an open collector driver on the Lamp terminal.
Together, the +5.5V and Lamp terminals provide power and switching for an external LED lamp. The
external LED lamp will be switched on when the contact on the external switching device connected
to the SWITCH and GND terminals closes.
