Operating Principle<\/strong><\/span><\/p>

\u00a0 \u00a0 \u00a0 \u00a0 When an alarm signal is occurred, it will initiate bell\/buzzer to operate. Meanwhile, it will produce output direct to the display LED, which makes LED flicking. After pressing an acknowledged push button, bell or buzzer remains silence but LED is steady on. If an alarm signal is return to normal status then the alarm is cancelled. However, the light of the indicating display LED will be sustained. Unless the reset push button switch is activated. Then the LED will be turn off and return to its initial condition. The \u201cTEST\u201d push button includes two functions; the first function is \u201cLamp TEST\u201d if push and hold this push button less than 3 seconds, it will light up all LED lamps at the front panel only. The second function is \u201cFunction test\u201d if push and hold this push button more than 3 seconds, the LED lamp will start flicking and bell\/buzzer alarms. This \u201cTEST\u201d push button is provided for checking purpose of all LED and operating functions at normal condition. While checking all LED and suddenly some of the alarm signals are occurred, the alarm sequence will be operated as usual without effect from the lamp test sequence. Alarm sequence can be selected by software for manual reset sequence or auto reset sequence as described as below.<\/span><\/p>

\u00a0<\/p>

SEQUENCE1 : MANUAL RESET<\/span><\/strong><\/span><\/p>

\u00a0 \u00a0 \u00a0 \u00a0 When an alarm signal is occurred, the LED would gently flash and bell or buzzer will activate continuously. To stop the sound of bell or buzzer, \u201cACK\u201d push button has to be pressed. Then bell\/buzzer is silenced but LED is still steady on. Reset is only possible by pressing \u201cRESET\u201d push button when alarm input returns to normal status.<\/span><\/p>

\u00a0<\/p>

SEQUENCE2 : AUTO RESET<\/span><\/strong><\/span><\/p>

\u00a0 \u00a0 \u00a0 \u00a0 When an alarm signal is occurred, the LED would gently flash and bell or buzzer will activate continuously. To stop the sound of bell or buzzer, \u201cACK\u201d push button has to be pressed. Then bell\/buzzer is silenced but lamp is steady on. Auto reset will take place simultaneously when alarm input returns to normal status.<\/span><\/p>

\u00a0<\/p>

INPUT INDICATOR FUNCTION<\/strong><\/span><\/p>

\u00a0 \u00a0 \u00a0 \u00a0This function is same as indicator lamp. When an alarm signal feed through an assigned input of Annunciator, the LED display lamp of that design fault will lid or steady on. After alarm input returns to normal then the display lamp will automatically switch off.\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
