SUBJECT:
Surveillance of Fort St. Vrain Seismic Accelerometer Trigger
REFERENCE:
PSC Letter Brey to Johnson dated November 7, 1984 (P-84478)
Dear Mr. Johnson:
In response to the comitment made in our November 7,1984 letter to send an accelerometer from Fort St. Vrain to be completely tested by the manufacturert the attached test report and associated certificates of calibration are submitted for your information.
Please note that the Fort St. Vrain seismic accelerometer trigger was within the specified tolerance.
If the southeastern Wyoming earthquake on October 18, 1984 had produced ground accelerations at Fort St. Vrain of 0.01g or greater, the seismic event would have been recorded as designed.

1.0 GENERAL DESCRIPTION AND OPERATIONAT. SEODENCE OF SYSTEM The VS-1 Seismic Trigger is an acceleration switch sensitive to vertical motion.
It can be purchased alone, enclosed in a machined aluminum housing and requiring an external power supply, or it can be built into any one of several Kinemetrics products including the SMA-1 Strong Motion Accelerograph.
When the applied acceleration reaches a
~
preset level, a SPST switch is closed, and stays closed for a preset time.
2.0 PURPOSE OF PROCEDURE The purpose of this procedure is the determination and adjustment, if required, of the trigger such that it responds to an input traceable to the National Bureau of Standards.
This test will also meet the requirements for Channel Functional Test and Channel Check.
Calibration may require removal of the device from its normal location.
3.0 PREODENCY It is recommended that this test be performed every 18 months or at refueling.

=iuaueraies 6.0 PERPORMANCE PRACTICES AND LIMITATIONS This procedure will also serve as the data sheet.
Because this procedure is intended for use by a trained Kinemetrics Field Engineer, detailed step-by-step instructions will not necessarily be provided.
If a deficiency is observed, the Field Engineer may undertake additional testing and install factory-authorized and/or calibrated replacement parts as necessary to restore proper operation of the sensors and systems.
Any situation which is not covered in the body of this procedure will be explained under " COMMENTS".
All equipment deficiencies and corrective actions will be reported under " COMMENTS".
Any item which cannot be brought into compliance with the requirements of this test will have a red REJECT tag affixed in a clearly visible location.
The tag will identify the item, show the nature of the deficiency, and recommend a course of action.
Unless otherwise noted, limits will be based upon Kinemetrics Inc. in-house acceptance tests and on reenmmendations found in ANSI N18.5-1974.
If an item is found to be outside those limits and cannot be adjusted sufficiently to satisfy this procedure, the Kinemetrics Field Engineer will recommend an appropriate course of action but it'will be the responsi-bility of the customer to act in accordance with plant policy and technical specifications.
It is assumed that the system under test is functioning properly. If neither a Channel Functional Test nor a Channel Check has been run within 45 days prior to this test, a preliminary Channel Check will be performed before beginning the Calibration.
