Zone lights (Model HC-CL4-SUPV Supervision
Dome/Zone Light with Buzzer)
Zone lights, like corridor lights, are intelligent dome lights used for
locating the sources of nurse calls. While corridor lights typically
pinpoint the room where the call was placed, zone lights show the
zone in which the room is located.
Zones may or may not coincide with duty areas. Facilities typically
mount zone lights at hallway entrances and in spots where nurses‘
station staff do not have direct line-of-sight views of corridor lights.
They are typically placed within sight of nurses‘ stations in order to
readily convey conditions prevailing in their areas.
Supervisory lights
If a Telligence System (LAN) has more than one staff console or
annunciator and a staff console or annunciator stops functioning,
error messages will appear at the other staff consoles and
annunciators (if so configured). When power and data supervision is
performed by other staff consoles and annunciators, supervisory
dome lights may not necessarily be installed near staff consoles and
annunciators, as they would be superfluous.
However, if your Telligence System has only one staff console or
annunciator, or if staff consoles and annunciators are located on
separate floors or are more than 25 feet (7.5 meters) apart, HC-CL4-
SUPV dome lights may be installed near and associated with each
staff console or annunciator. The dome lights will flash and also
sound a tone if the flow of power and data to the staff console or
annunciator is interrupted.
The HC-CL4-SUPV supervision dome/zone light with buzzer may be
located near a staff console or annunciator to alert staff if the
device fails. The HC-CL4-SUPV dome light‘s four light sections fast
flash white and sound tones in time with the flashing of its lights to
signal loss of power, and consequent loss of data, to the device. The
supervision dome light is required to maintain compliance with UL
1069.
Passive dome lights
Dome lights located inside patient rooms (typically near
bathroom doors) are called passive dome lights, since they
perform only simple notification functions, turning on as a
result of a button press or a cord pull, and turning off after the
button or cord pull has been cancelled.
The HC-CL1-RED dome/zone light model is used for passive dome
lights. It has a single red light section and is non-configurable. The
HC-CL1-RED dome/zone light can be located any place where
secondary visual call annunciation is needed.
