BYPASS is used to move Tags through a controlled area without triggering an alarm. The GREEN light will
alternately flash with the RED light when the unit is in Bypass.
During Bypass mode:
• you have 8 seconds to bring the transponder into the field after entering the Bypass code on the
Keypad, or the system will re-arm
• once the Tag is in the field, bypass will end 8 seconds after all Tags leave the field or the door
closes, or the maximum Bypass time is exceeded. Bypass can also be terminated by a Reset from a
Keypad.
• once you enter the field you have 90 seconds to pass through the detection zone
• if you passed through within 90 seconds the system will rearm within 8 seconds or the system will
go into alarm after 90 seconds.
• Any Tags still in the detection area 10 seconds after the door closes will be reread so they can
trigger an alarm if necessary.
RESET request will turn off the TIC-alarm relay or terminate the Tag Alarm if the Continuous Alarm mode
was selected and there are no more Tags in the field. It takes the controller 6 seconds to recognize that the Tag
has actually left the field.
STANDBY: The YELLOW light indicates the system power supply is ON.
ALARM: The RED light flashing indicates that the controller is in Alarm. A beeper also provides an audible
alarm indication when this light is on. If the door is open, the Alarm light and beeper will beep with a long ON
time and the Alarm Relay will turn ON. This alarm will also be reported at the HALO PC Console.
Pre-Alarm (Nurse Saver Feature)
If the door is closed and there is a door switch installed, the Alarm light and beeper on the keypad
associated with that door will turn on and off with a short ON time, when a Tag enters the field.
This is a known as a pre-alarm condition as a bad Tag is in the detection area but the door hasn’t
opened. Such an event is indicated at the HALO PC Console by a change in the appropriate floor
button, and the device icon, from their normal color to yellow.
Loiter Alarm
If the Tag remains in this field for 70 seconds, a “Loiter” alarm is reported at the HALO PC Console
and the associated floor button, and device icon, turn red.
READER MODE: A constant GREEN light indicates that the associated Controller is in “Reader Mode”. That
is, the HALO system software has disabled that particular Controller for normal Tag communications, and has
enabled the Controller to detect the presence of Tags not in the Database inventory, for the purpose of adding
such Tags into the Database inventory.
The Keypads allow a unique programmable code for both reset and bypass. The Keypads come preset with
default codes of “1938” for Bypass and “1939” for Reset. Refer to Keypad programming sheet for
instructions on how to change these codes.
