Bell For Institutes, 16 Times Programmable
Bell For Institutes, 16 Times Programmable
Perfect Electronics has recently developed a programmable bell for use in institutes or industries. It includes a built-in clock. Maximum 16 timings can be fed to the unit. If a weekly mode is selected, the bell will ring at the same time every day. It is possible to keep the timing off on Sunday. Different timings can be fed for every day of the week. Difference between any two consecutive timings should be minimum one minute and maximum 23 hours, 59 minute. 10 seconds delay for every time is given so that bell will sound only for 10 seconds. If the mains power has failed, the bell will not sound but the built-in clock operating on back-up cell ensures that the programmed times are not disturbed. UPS or EPS can be used with this system so that the bell will sound during the mains failure. The same can be used as home security system. Load can be connected up to 400 W.
