Manual Actuation Device（MC-1）

The Manual Actuation Device (MC-1) is a key auxiliary operating component in industrial fluid control systems, pressure equipment, or safety circuits. Its core function is to directly drive end actuators (such as valves and switches) through manual operation when automatic control fails, power is cut off, or under special operating conditions. This ensures the system remains controllable, serving as the "last manual line of defense" for safeguarding the safe operation of industrial equipment.

Product Formation

Manual Actuation Device is a critical safety redundancy component in fire automatic control systems, specially designed to "rapidly and reliably initiate fire - protection equipment when automatic control fails or manual intervention becomes necessary."

Its core value lies in establishing an "automatic + manual" dual - protection mechanism: When automatic modules—such as fire alarm systems, fire linkage controllers, or centralized control systems—malfunction, lose power, or break down in signal transmission, this device acts as an independent trigger to directly activate key fire - fighting equipment (e.g., fire pumps, smoke exhaust fans, fire shutter doors). It ensures that core fire - safety functions like fire suppression, personnel evacuation, and smoke containment remain uninterrupted, making it the "last line of manual defense" mandated by fire codes worldwide.

Product Features

1、All-metal structure for mechanical reliability in extreme environments

The device boasts a robust all-metal construction (stainless steel + aluminum alloy), ensuring unwavering mechanical performance even in harsh fire scenarios—such as high temperatures (+85℃), high humidity (95% RH), or dusty conditions—delivering a mechanical lifespan of ≥100,000 operations with zero electrical failure risks.

2、Red sliding protective cover to prevent accidental activation

The operation button is equipped with a red sliding protective cover that requires manual sliding to open before use. This design effectively prevents accidental touches during daily maintenance or emergency evacuation, eliminating unintended device activation.

3、Standardized interfaces for multi-device compatibility (no system modification needed)

Equipped with standardized connection terminals, the device seamlessly adapts to over 90% of fire protection equipment (e.g., fire pumps, smoke exhaust fans, fire shutters). It requires no system modification or rewiring, streamlining installation and integration with existing fire control circuits.

4、Low-voltage design for safety compliance

Operating at a safe DC 24V voltage (well below the 36V human safety threshold), the device aligns with fire system low-voltage control circuit standards. This not only eliminates the risk of electric shock to operators but also meets NFPA 72 (US) and GB 16806 (China) certification requirements for personnel safety.

5、Two-step operation for instant triggering (3 seconds max, even in panic)

Activation requires just two intuitive steps: slide open the protective cover → press the operation button. With an actuation force of ≤5N (compliant with EN 18081 ergonomics standards), it can be triggered within 3 seconds—even if operators are wearing thick gloves or in emergency panic—ensuring rapid response when every second counts.

6、Direct mechanical actuation for zero-delay startup

Unlike electronic-dependent devices, the MC-1 uses mechanical actuation to directly connect to the fire equipment control circuit, bypassing complex electronic modules. This design eliminates start-up delays caused by circuit failures, guaranteeing “press-and-go” reliability—critical for life-saving actions during fires.

Usage Instructions

⚠️ During installation, ensure the medium flow direction is consistent with the arrow on the valve body; reverse operation is strictly prohibited!

⚠️ For the high-temperature type of the valve, the temperature range must be clearly specified when placing an order to avoid damage caused by material mismatch.
