Description<\/span>
<\/strong><\/span>\u00a0 \u00a0 \u00a0 \u00a0 ESPAN02 series is designed to use as an alarm system for general protection switchboard, local control panel of GIS, local control cabinet of power transformer and all of control panels, which needs alarm function.

Operating Principle\u00a0 \u00a0 \u00a0
<\/span><\/strong><\/span>\u00a0 \u00a0 \u00a0 \u00a0When an alarm signal is occurred, it will initiate horn\/buzzer to operate. In the meantime, it will send an output directly to the display lamp, which makes the lamp flicks. After pressing an acknowledged push button switch, horn or buzzer remains silence but the lamp is still steady on. If an alarm signal is returned to normal status then the alarm is cancelled. However, the light of the correspondent indicating display lamp will be sustained. Unless the reset push button switch is activated then the lamp will be turned off and return to its initial condition.<\/span><\/span><\/h3>

\u00a0 \u00a0 \u00a0 \u00a0 The lamp test switch is also provided for checking all lamps at normal condition. While checking all lamps and suddenly some of the alarm signals are occurred, the alarm sequence will be operated as usual without any effect from the lamp test sequence. Alarm sequence can be selected by selector or dip switch for manual reset sequence or auto reset sequence, which described as below:<\/span><\/h3>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\u00a0 \u00a0 \u00a0 In this mode, the momentary fault inputs will be latched until acknowledgement is manually reset to clear.

\u00a0 \u00a0 \u00a0 \u00a0 \u00a0When an alarm occurs, the lamp would flash and horn\/buzzer will activate continuously.
