SN430A 10-Channel Group Annunciator Module | Marine Machinery Alarm Monitor (SSP-931105)

SN430A High-Reliability 10-Point Group Annunciator System

Maintain total situational awareness over your vessel’s critical hardware pipelines with the SN430A Group Annunciator Module. Designed as a dedicated multi-point fault monitor, this module acts as a bulletproof safety sentinel, watching over dry-contact sensors distributed across primary propulsion systems, water pumps, and generator sets to ensure abnormal states are instantly flagged before mechanical damage can occur.

As displayed across the multi-angle views, the text-etched front black face contains an array of direct-access engineering adjusters and dual-stage diagnostic LEDs:

• Alphanumeric Alarm Matrix: Formatted with 10 discrete monitoring paths (ALARM 1 to ALARM 10) alongside a centralized COMMON channel and an adjustable FLICKER TIME controller for pulsing flash loops.

• Independent Delay Pots: Every single alarm line features an internal blue trimmer potentiometer to calibrate individual Delay Times. This lets engineers filter out temporary sloshing spikes or pressure fluctuations to eliminate annoying false alarms.

• Dual LED Status Windows: Each tracking channel is outfitted with a green POWER indicator lamp to verify active wiring integrity and a red ALARM indicator to flag tripped sensor exceptions.

The structural profile is built for quick maintenance tracking and tight mechanical connectivity:

• Pluggable Screw Terminals: Features an extensive single-row blue screw barrier terminal block along the lower framing edge, clearly stamped with identifier markings (110, LT, N, P) for secure loop connections.

• Robust Glass-Epoxy Backplane: Built over a heavy-duty green circuit board layout marked SSP-931105 with thick copper tracing to maximize vibration immunity across vessel hulls.

• Ventilated Rigid Metal Chassis: The dense matte-black casing includes active side cooling slots to reject panel heat and integrated corner bracket ears for straightforward surface-mount fastening.

Key Features:

• Pure Hardware Determinism: Operates entirely on solid-state, discrete component routing without standard computer processors. This removes any risk of software lockups or operating system lag during critical emergency power drop events.

• Custom False-Alarm Filtering: Individual delay pots give technicians precision tuning control, letting you assign short delay filters on slow-changing levels while executing immediate responses on high-priority oil lines.

• Vibration-Proof Tunnel Terminals: Pluggable terminal blocks guarantee absolute wire clamping security, locking sensor wires securely in place against continuous diesel engine harmonic shaking.

• Modular Control Panel Integration: The compact, enclosed black box footprint with pre-drilled flange anchors allows effortless drop-in integration into existing steel breaker cabinets or custom dashboard frameworks.
