Corrosion-resistant alarm display panel KNRAP2

vandal-proof

Overview
The KNTECH KNRAP2 is an industrial remote alarm indicator panel for PABX systems, offering visual and audible alerts for Major/Minor alarms to support rapid fault identification and response in 24/7 operational environments.

Product Identification
Model: KNRAP2
Size: 150mm (H) x 130mm (W) x 40mm (D)
Material: SUS304 Brushed Stainless Steel Faceplate (1.2mm)

Key Features

• Durable construction with SUS304 brushed stainless steel faceplate and vandal-resistant metal controls.
• Dual alert system: high-brightness Green/Red LEDs and Piezo buzzer >75dB.
• Integrated MCU and relay logic with Alarm Mute function: buzzer silenced while Red LED remains lit until fault clearance.
• Wall-mount design with standard installation procedure for easy integration.

Operation Logic

• Normal State: Green LED steady, buzzer OFF.
• Alarm State: On fault signal from PABX, LED turns Red (steady or flashing) and buzzer sounds intermittently.
• Mute Action: Press MUTE — buzzer OFF (acknowledged) while Red LED remains ON as visual reminder until fault is cleared.
• Recovery: On fault clearance, system auto-resets to Normal State (LED returns to Green).
