5.10.8. System Adjustment and Testing
Upon completion of the installation, follow this procedure for testing the system operation:
Power on the system, and set the Test Switch on the Audible Alarm Module to “Test”.
Expose a Transponder within the elevator cab. The pre-alarm beeper will beep as the system senses the
Transponder within its field. The closer the beep intervals, the greater the sensitivity of the
Transponder to the exciter field. Try various orientations and positions of the Transponder within the
cab (don’t forget the floor!), to ensure adequate coverage.
In the event that the field appears to be too strong, indicated by the fact that a Transponder is sensed
well outside the elevator cab, adjust the “Range Adjust” setting within the HALO Controller located
inside the Cabinet to optimize the exciter field (see Threshold setting instructions for HALO Controller
in Section 5.7.1.5)
Set the Tests Switch on the Audible Alarm back to Normal Operation.
Enter the elevator with a Transponder, which should immediately trigger a pre-alarm beeper tone
lasting for 11 seconds. The Alarm light on the Keypad will flash momentarily during this time.
Leave the elevator cab within the 11 seconds, or place the Transponder within its metal foil bag
(making sure it is tightly sealed). The system should reset itself and release the doors for normal
operation at the end of the 11-second pre-alarm period.
To test the Bypass function, expose the Transponder within the cab. The pre-alarm beeper will trigger.
Enter “1938” on the Keypad, which should now allow normal operation of the elevator.
Test the “full alarm” mode by exposing a Transponder within the cab for greater than 11 seconds.
After the pre-alarm beeper is heard for the 11-second duration, a loud alarm will begin. If the
Transponder is removed from the cab during the full alarm period, the system should reset itself within
6 seconds.
5.11. SYSTEM GROUNDING CONSIDERATIONS
The difference between successful installations that are free of noise versus those that are plagued with
unreliable operation is often poor grounding of the system elements. Ensure that no ground loops exist in the
system, and that all the system components are adequately grounded.
The figure below shows ground requirements for Controllers in the system. The chassis of the Controller is
connected to the building ground. The Receiver is also and the power supply and RS-485 grounds are
connected together for both the Controller and Receiver so that the signal at the RS-485 interface is referenced
correctly.
