Ansul Mechanical Automan Regulated Release Mechanism – Model – 429853



Ansul Automan

is a trade name for a regulated mechanical release assembly used in fire suppression systems by Ansul, a company specializing in fire protection [2].

Here’s a breakdown of what it is and how it works:

  • Function: The Ansul Automan is a key component in releasing extinguishing agent in a fire suppression system. It houses the mechanism that controls the pressurized gas that pushes the fire suppression agent out of the tank. [3, 4]
  • Components: It typically consists of a metal enclosure, a regulated release mechanism, and knockouts for connecting piping for detection systems and the agent tank (which is sold separately). [3]
  • Activation: There are two main ways to trigger the Ansul Automan:
    • Automatic: A fusible link detection system can be connected. When the surrounding temperature reaches a certain threshold, the link melts, triggering the release mechanism. [3]
    • Manual: A mechanical pull station can be connected for manual activation. [3]

Benefits of Ansul Automan:

  • Versatility: The Ansul Automan can be used in various fire suppression system configurations, including single, double, and multiple agent tanks. [3]
  • Durability: Ansul fire suppression products are known for their rugged design and compliance with strict safety standards [4].
  • Reliability: The regulated release mechanism ensures a consistent and controlled discharge of the extinguishing agent. [3]

Important to Note:

  • Installation should only be done by qualified professionals familiar with fire suppression systems and Ansul products [3].
  • The Ansul Automan is a part of a larger fire suppression system and should not be considered a standalone fire extinguisher.

For further information on Ansul Automan and its compatibility with specific fire suppression systems, consulting a qualified fire protection specialist is recommended.

  1. Materials: Typically constructed from durable materials such as stainless steel or heat-resistant alloys to ensure reliability and longevity.
  2. Activation Mechanism: The release mechanism is often triggered by a heat-sensitive fusible link or other detection devices that detect the presence of fire or excessive heat.
  3. Operating Temperature Range: The device should be designed to operate within a specific temperature range, ensuring reliable activation under various fire conditions while minimizing false alarms.
  4. Activation Time: Specifies the time it takes for the release mechanism to activate once the predetermined conditions are met.
  5. Pressure Ratings: If applicable, the release mechanism may have specific pressure ratings to ensure compatibility with the fire suppression system’s components and operating conditions.
  6. Compatibility: Designed to be compatible with specific fire suppression systems, such as ANSUL R-102 systems, ensuring seamless integration and performance.
  7. Certifications and Compliance: The device may be certified by relevant regulatory bodies or standards organizations, ensuring it meets industry standards for safety and performance.
  8. Dimensions: Includes dimensions such as height, width, and depth to facilitate proper installation within the fire suppression system enclosure.
  9. Installation Requirements: Specifies any special considerations or requirements for proper installation, such as mounting orientation or clearances.
  10. Maintenance Intervals: Recommends maintenance intervals and procedures to ensure the continued reliability and functionality of the release mechanism.
