Questions and answers
THE PROGRAMMED BELLS WONT RING
The programmed bells on the Toa TT-104B may not ring due to the following reasons:
1. Incorrect Program Registration – The programs may not be correctly entered in the program table or assigned to the correct output channel.
2. Clock Not Set Properly – If the current time or day settings are incorrect, the programmed schedule may not activate as expected.
3. Memory Backup Switch – If the rear-mounted MEMORY BACKUP switch is ON, the clock will work, but no timer output will be delivered.
4. Relay Contact Behavior – The output relay of the TT-104B only makes contact for five seconds at the programmed time and cannot be manually kept connected or disconnected.
5. Environmental Factors – High temperatures or interference from nearby electronic devices like amplifiers or wireless microphones could cause clock inaccuracies.
6. Power Issues – If the power cord is unplugged or there was a power outage without proper backup, the timer may not function correctly.
7. Equipment Connection – The connected equipment may not be properly wired to accept the pulse output from the TT-104B.
Checking these factors can help diagnose why the bells are not ringing as programmed.
