Can this bell controller work with my existing electric bell or buzzer, or does it need a special bell unit?

Yes, this is a timer-based controller switch rated at 220V AC with a conventional thermal current of 16A, so it can drive most standard electric bells, buzzers, or sirens already installed in your premises. Simply wire it in series with your existing bell circuit — no special bell unit is required as long as your bell operates on 220V AC and draws under 16A.

How many unique ring schedules can I set, and do they repeat automatically every week?

You can programme up to 40 timing groups in total, and yes, the schedule is weekly and repeats automatically — once set, the controller rings on the same days and times every week without any manual intervention. Each group lets you define the day(s), start time, and ring duration independently.

What is the timing accuracy of this controller, and will it drift over time?

The specified timing error is 1 second per day, which is well within acceptable limits for institutional use. Over a week, the maximum drift would be around 7 seconds, and most users find a quick monthly time-sync check is sufficient to keep it accurate.

Can I set different ring durations for different periods — for example, 10 seconds for a warning bell and 30 seconds for the final bell?

Absolutely — each of the 40 programmable groups has its own independently adjustable ring duration settable anywhere from 1 to 99 seconds. So you can configure a 10-second warning bell for one slot and a 30-second end-of-period bell for another, all within the same weekly programme.

Does the controller retain its programmed schedule during a power cut, or do I need to reprogram it after every outage?

The onboard memory retains all 40 programmed schedules even during a power outage, so your settings are not lost. However, like most timer controllers, the real-time clock may need to be re-synced after a prolonged power cut to ensure the time remains accurate.
