7.3. HALO CONTROLLER
Figure 24 – Halo Controller Front Panel
The HALO controller handles all communication with the Tags, provides audible and visual indicators of
what state its in and prevents egress when necessary. This device is fully capable of operating in stand-
alone mode although it does provide for communication to several different types of central reporting
systems. The front panel provides easy access to a number of different output formats as well as allowing
inputs to alter some of its automatic functions as necessary. Local alarm and bypass annunciation is
available through the DKX Keypad.
The Tag serial numbers as well as status information is output in Weigand format on 2 of the output pins.
This is a standard format used by many Card Access Systems. The MagOut line will engage a Magnetic
Door Lock when Tag’s are detected in the field. Due to NFPA 101 regulations being adopted in many
locations, it may be mandatory to provide an automatic door release with 15 seconds after a door has been
locked up. The controller provides 2 Form-C dry contacts rated at 1 Amp @ 30VDC. They will provide
normally open or normally closed contacts and will change state to indicate the 2 different alarm conditions
– Tag In Field (TIF) and Tag Initiated Communication (TIC). These Relays can be used to turn on remote
signaling devices such as:
- Nurse Call system annunciators (should have latching function)
- EXI model “SSM” 2-zone audible alarm with selectable tone sequences
- EXI model “ANN-6L” Audible-Visual 6-zone, LED type non-supervised Annunciator
See Appendices for details.
The HALO controller uses the Door Switch input to disable alarm reporting, when the door is closed. This
is known as the Nurse Saver Feature. Although Tags are still detected and reported to a central system, no
alarms are annunciated until the door opens. At that time, all the Tags are re-read by the controller so that
only the Tags that are still in the field will cause an alarm. The door switch is also useful during bypass as
the controller will detect the door opening and then terminate the bypass as soon as the door closes. In the
event that a Tag is detected at the door with the door being closed, and the Tag remains at the door for a
period exceeding 70 seconds, an Alarm condition is created. This is known as the Loiter Feature,
preventing a patient from waiting at the door for an opportunity to exit when the door is bypassed, or
otherwise opened.
A remote system or switches can use three input lines to alter the normal operation of the controller.
Unlock In provides a temporary release of the door, for a system override such as that from a fire alarm
control.. Alarm in will cause an immediate lockup of the door with the local and remote alarm
annunciators on. Override In will disable the controller so that no tags are read and nothing will be
reported to the Host computer. Shorting the appropriate line to system ground will activate the function.
