ZYT22-AD AUTOMATIC BELL TIMER

Bell Timer ZYT22-AD BellTimerhas a high performance microcomputer chip as the core inside,with the function of calibration clock. It can be realized 80 times ringing bells within one day and widely be applied in schools and other enterprises. 2.Comparison The Ringing Bell Timer Working voltage Conventional voltage: AC220V Other: AC380V, AC220V, AC110V, DC12V, DC24V, DC36V Model ZYT08 ZYT22 Load capacity Resistance 25A AC Voltage output: resistance 2A; DC Voltage output: resistance 2A Max ringing last 23h 59h 59s Consumption power 4W Timing error 0.5s/day Dimension 126×88×51mm 195×175×85mm Weight 400g 510g 3.For example There is a school has the working schedule as follows: On duty: 8:00-12:00 am 14:00-18:00pm From Monday to Friday. On duty: 8:00-12:00 am for Saturday The setting is following: 1. It needs to set 4 times ringing as the figures. 2. To choose the program serial number, press “+” to change it to 05, press “manual” key and “+” key for 3s, to cancel the program group later, make it as “--:--”. 3. Long press “MODE” key, make the system return to the clock state. 4. Press “MANU” key, make the control state as automatic. 5. Switch “manual/auto” key on the right to “auto”. Advantages: 1. AC220V and DC12V power can be used at the same time 2. Backup power. Once it loses power at schools or factories, it will be used by DC12V power
