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.
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.
• The SWITCH and LAMP circuits are not electrically isolated.
• The cable length for the SWITCH circuit must not exceed 33ft (10m) and the cable must be
appropriately separated from power cables and sources of electromagnetic interference.
• The LAMP circuit is power limited to 5.5Vdc at 50mA.
• The SWITCH circuit is power limited to 5.5Vdc at 50mA.
