Technical Specification

General:

• Product Type: Failure Alarm Panel / Indicator Panel / Alarm Annunciator
• Function: Provides visual and audible indication for a single failure/fault condition.
• Compliance: Likely designed to meet relevant marine standards (e.g., IEC 60945 for marine navigational equipment, and potentially sections of Classification Society rules for alarm systems).

Electrical:

• Power Supply: 24 VDC (nominal)
  • Operating Voltage Range: Typically 19.2 VDC to 28.8 VDC (standard for marine 24V systems).
• Current Consumption: Low, likely in the range of tens of milliamps (e.g., < 50 mA without external load).
• Inputs: One (1) binary input (e.g., dry contact, potential-free contact, or specific voltage level).
  • Trigger Type: Configurable for Normally Open (NO) or Normally Closed (NC) contacts, or specific voltage levels (e.g., 24V active high/low).
• Outputs:
  • Alarm Relay Output: May include a relay output (e.g., potential-free contact) for transferring the alarm status to a central alarm system or another indicator.
  • Buzzer Mute Output: (If externally controllable).

Performance:

• Alarm Indication:
  • Visual: LED indicator (e.g., red or amber, flashing when active, steady when acknowledged).
  • Audible: Integrated buzzer.
• Audible Alarm Level: Typically 80 dB(A) or 85 dB(A) at 1 meter.
• Controls:
  • Acknowledge/Mute Button: For silencing the audible alarm.
  • Test Function: May include a test button to verify the panel’s functionality.
• Alarm Logic: When a fault condition is detected, the visual alarm activates (e.g., flashes) and the audible alarm sounds. Pressing “Acknowledge” mutes the buzzer, and the visual alarm remains active (e.g., steady) until the fault is cleared.

Physical & Environmental:

• Dimensions (WxHxD): Typically compact for flush mounting. For similar SM-Electrics panels, common dimensions are often around:
  • Front Bezel: Approx. 72 mm (W) x 96 mm (H)
  • Cut-out: Approx. 68 mm (W) x 92 mm (H)
  • Depth: Approx. 60-75 mm (D)
• Mounting: Designed for flush mounting in a panel or console.
• Material: Robust, often black or grey marine-grade plastic or metal casing.
• Ingress Protection (IP) Rating:
  • Front Panel: Typically IP23 or IP44 (for indoor, panel-mounted applications, protected against sprays of water).
  • Rear/Terminals: Lower IP rating as it’s designed to be enclosed.
• Operating Temperature: -15°C to +55°C (standard marine operating range).
• Storage Temperature: -25°C to +70°C (standard marine storage range).
• Vibration: Compliant with marine equipment standards.
