ALM-CH12 12 Window Annunciator

Information

ALM-CH12 is a compact 12 window annunciator, also known as 12-channel fault annunciator, specially designed for panel mounting on electrical control cabinets. Equipped with 12 independent display windows, each window matches a high-brightness red LED indicator for separate fault signal display, with replaceable custom label strips for marking equipment fault descriptions. It adopts standard 96×96mm panel installation size, supporting universal wide power supply of 85–265VAC/DC (optional 24VDC), and applies stable MCU chip to realize real-time acquisition of 12 groups of passive dry contact fault signals without external power supply for each input channel. This 12 window annunciator integrates complete visual and audible alarm logic. Once any of the 12 channels triggers a fault signal, the corresponding window LED flashes continuously above 1Hz with built-in buzzer sounding simultaneously. Three physical buttons (MUTE, TEST, RSET) on the front panel support one-click operations: mute alarm sound, full lamp self-test, and alarm acknowledgement reset. After reset, the LED keeps steady on if the fault persists and turns off only after the fault clears. It is configured with three groups of passive relay outputs: centralized alarm output, external buzzer drive output, and self-fault alarm output. If the annunciator loses power or has internal circuit failure, the self-fault contact sends out warning signals automatically. Besides, isolated RS485 Modbus-RTU communication port enables real-time upload of all 12 window fault status to remote SCADA and centralized monitoring platforms.
