The ESPAN-01 series Annunciator system is simple for installation by using detachable connector concept which managed most of the wiring. Besides, it is convenience for maintenance. Only the malfunction module of the three separate-modular module can be repaired or changed.
The operation sequence of the Annunciator is as following; when the fault signal is occurred in each input, an alarm output signal is sent toward bell/horn or buzzer which can be pre-selected as heavy fault (bell/horn) or light fault (buzzer). At the same time, it will send flicker output to the set style indication lamp that corresponds to each I/O channel. After pressing an acknowledged push button switch, if an alarm-contact is returned, then the alarm is canceled. However, the indication window is steady on unless the reset pushbutton switch is activated. Then the lamp will be turn off and ready for the next operation.
The lamp test push button switch is also provided for the purpose of checking lamp at normal condition and while checking the lamp, if a fault occurs, the operating alarm sequence will be operated as usual with no effect from the lamp test sequence anymore.
Function Test of ESPAN-01 Annunciator : if the lamp test push button switch is pressed more than 3 seconds, all the display window lamps would flash with audible sound alarm. (bell/horn or buzzer)
