Chapter 6 Component Competency – Call
Stations
One of the primary advantages that the Alliance AllCall© Wireless
Nurse Call System has over conventional hardwire nurse call systems, is
the flexibility of call stations. Alliance’s Wireless Nurse Call System offers
conventional bed stations with push button call cords and pull string bath
calls. Additionally, an optional emergency push button call station can be
ordered. Finally, the Wireless Nurse Call System supports the use of neck
and watch pendants. Because the system is wireless, the call stations are
100% modular, and are simply held to the wall by two screws. There are no
wires to keep track of. The wireless communication is handled by GE’s
rugged and proven wireless door window sensors.
AllCall© Bed Station
The AllCall© Bed Station is constructed from a tough
plastic enclosure, screen printed and pre-punched to
receive the hardware. The call station works by pushing a
momentary button on the call cord which plugs into a ¼”
jack on the face of the call station. When the momentary
button is pressed, an after-market flip-flop board that
mounts directly onto the transmitter latches and sets the
wireless transmitter into alarm. The flip-flop board also
turns on a red LED on the face of the call station alerting
the resident or staff person that the call station is in alarm. When the need
has been taken care of, the staff person then presses the reset button. This
resets the flip-flop board and turns the LED off.
When the face of the call station is removed, there are three primary
components to be aware of. The wireless transmitter, the LED battery
board and the flip-flop board which is mounted inside the transmitter’s
enclosure. (See figure 16) Note the battery sizes, the LED battery is a 3.6v
