perpetual alarm clock module

This is a LCD 4 channels perpetual alarm clock module with 3 tact switches on the front. The PCB Size is 70 x 51.2 mm, while plastic frame is 58 x 40 mm. Four daily alarm channels are built-in. This is 24-hour system. 12-hour system is available upon request. Two options of alarm method are ready for choice, 1) one minute regular audible alarm or 2) endless or perpetual audible PSEA (power saving endless alert) alarm. Due to its significant power saving by applying PSEA alert circuit, this clock module is good to be used for long term reminding, such as pill or dosing reminding, job reminding, wake up reminding, or any daily activity. To confirm and stop alarm, just press the "confirm" (i.e., mode) key once.

A piece of UM4 (AAA) battery holder is mounted on the backside normally. But all the necessary soldering pads for external connection such as power supply, and keys are ready at right hand edge of PCB.

As well as audible alarm output pole, this alarm clock module also provides level or pulse signal output poles for each individual alarm channel or compiling in one single pole. The soldering pads are ready at the left edge of PCB.

Built with three friendly operated keys, "mode", "set", and "adjust". Press "mode" key to switch normal display into each alarm channel. Press "set" key to enter setting mode of current time, and then press "adjust" key to change its reading. Various options of key combination are available upon request. It provides product designer more flexibility of creating a 2 keys, 3 keys, 4 keys, or 5 keys product. For 2 keys, the "mode" and "adjust" are combined together into one key. For 5 keys, the additional two keys are " snooze", and "second reset". The "snooze" key is applied for the primary alarm channel only. For 4 keys version, people may select "snooze" or "second reset" as the additional key.

Furthermore, the features of sophisticated combination and options of output poles allow circuit engineer has more options to be selected for more comprehensive applications.
