Description: Venson Electric manufactures J-Watch microprocessor based alarm annunciator. The depth and the height of the unit are uniform for the entire range of 4 to 24 windows. The power supply card is of a proven design, immune to line surges and noise which are common in high voltage receiving stations. The facility is provided in the front of each unit for convenient programming of all functions. The trip and non-trip function selection of each window and also the operational sequence selection (as per ISA standard) are programmed from front operated DIP switches. The annunicators are facilitated with a set of inbuilt push buttons for alarm, silence, test, accept and reset functions that eliminates the need for external push buttons and inter connection wiring. However, terminals for terminating external push buttons are also provided as a standard feature. The windows are lit by red super bright LEDs, yellow, amber, green, or blue LED with color filters can also be provided at specific request. The unit works on an AC aux supply normally of 240V, 50 Hz. A normally closed contact of DC monitoring, relay is used to energize AC aux relay, which will activate the annunciation scheme and illuminate the designated window. It is supported with RS 232 or RS485 communication port.
