Narrative:

Runway 28's glide slope goes into alarm when the ILS runway 10 is selected. The ILS's are independent. When one is selected, the other is supposed to be turned off. Because of the chronic alarms, management has authorized the use of rubber bands to silence these alarms. The problem is that this does not fix the problem. Occasionally runway 10's glide slope does the same thing when runway 28 is selected. A rubber band will not silence runway 10's alarms. For runway 10, we put a tape dispenser on top of the button to silence the alarm along with management's blessing. Callback conversation with reporter revealed the following information: reporter alleges that maintenance has advised that they do not have the time to troubleshoot and correct this problem. The rubber band and the tape dispenser are the current approved modes to override these alarms.

Title: AGC TOWER RWYS 10 AND 28 GS ALARMS WHEN ONE OR THE OTHER IS SELECTED TO INITIATE THE RWY'S ILS SYSTEM.

Narrative: RWY 28'S GLIDE SLOPE GOES INTO ALARM WHEN THE ILS RWY 10 IS SELECTED. THE ILS'S ARE INDEPENDENT. WHEN ONE IS SELECTED, THE OTHER IS SUPPOSED TO BE TURNED OFF. BECAUSE OF THE CHRONIC ALARMS, MANAGEMENT HAS AUTHORIZED THE USE OF RUBBER BANDS TO SILENCE THESE ALARMS. THE PROBLEM IS THAT THIS DOES NOT FIX THE PROBLEM. OCCASIONALLY RWY 10'S GLIDE SLOPE DOES THE SAME THING WHEN RWY 28 IS SELECTED. A RUBBER BAND WILL NOT SILENCE RWY 10'S ALARMS. FOR RWY 10, WE PUT A TAPE DISPENSER ON TOP OF THE BUTTON TO SILENCE THE ALARM ALONG WITH MANAGEMENT'S BLESSING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR ALLEGES THAT MAINT HAS ADVISED THAT THEY DO NOT HAVE THE TIME TO TROUBLESHOOT AND CORRECT THIS PROB. THE RUBBER BAND AND THE TAPE DISPENSER ARE THE CURRENT APPROVED MODES TO OVERRIDE THESE ALARMS.
