Author Topic: TA-10 alarm Paul G. Thompson The Weenie Man Posts: 4718 From: Mount Vernon WA USA Registered: Nov 2000 posted 10-16-2001 12:48 AM                     I have two TA-10's that will not sound the built-in alarm when the projector shuts down for no apparent reason, although I would suspect the film presence or film motion detectors would be causing the shut-down. The reason why I think this is because the shutdown problem goes away after I straighten out the lower guidance hardware that was wanged out of position by a club-footed projectionist dancing on the film path. However, the alarm will sound on tail-out if the detector misses the shut-down cue. Any suggestions as to why the alarm does not sound when a fault is detected? The alarm sounds ONLY if the film tails-out.  |  IP: Logged Ken Layton Phenomenal Film Handler Posts: 1452 From: Olympia, Wash.

Supposedly, these were new units as of August of this year.

He is very good at this sort of thing and will help you get to the bottom of it without a lot of guesswork. ------------------ Bill Purdy Component Engineering  |  IP: Logged Paul G.

House No. 2 and 3 were shutting down at exactly the same time. The only thing these houses have in common is the 3 phase power. The problem may be caused by dirty power. It appears when the booth's A/C cycles, it takes the booth lighting into a dip. The power dip lasts about 200 milli-seconds, enough to almost extinguish some of the flourescent lights in the secure areas. I don't think two of the automations like it.

If so, check the address on the dip switches. I had a theater that was wired for interlock, but the switches were never set so when one machine shut down, so did several others. I would not have found this without Don Olsen, and I strongly suggest you talk to him if you still have problems. He has saved my butt on many occasions!!  |  IP: Logged Paul G.

The only connection common to the two automations is primary power, and nothing else. And, yes, I will get in contact with Don Olson.  |  IP: Logged Paul G.

There are a few more things to check. I am confident I will get this problem resolved, and when I do, I will post it for you all.  |  IP: Logged
