Keeping Your Engine Test Cell Safe – Alarms and System Protection

Posted on: October 21st, 2014 No Comments

Alarms and Systems Protection

Designing a Test Cell is a complex process. It is important to have experienced, engineering professionals help you throughout the planning and implementation process. A key factor in your success is determining the major system components and how they integrate together for a Test Cell that is safe, convenient and well-organized. Inadequate planning and design can amount in huge costs to your company leaving you with an end result that does not provide an optimal solution. In part three of this three part series, we will briefly explain the importance alarms and system protection can have on Test Cell safety.

Stop Kits and Safety Alarms

All Test Cells should have an Emergency Shutdown system. Emergency Stop Kits are designed to power down the system in the event of an emergency. Traditionally, Emergency Stop Kits shut off electrical power from all devices associated with the running of the engine. It is important to install these kits in the proper locations so that the stop button is easily accessible and can be pushed immediately in case of an emergency.

Safety alarms can also be installed. The following is a list of suggested alarms; refer to your manufacturer’s specifications as alarms may vary per your application:


  • High water temperature 210°F (99°C)
  • High oil temperature 248°F (120°C)
  • Low oil pressure 10 psi (70 kPa)
  • Manifold temperature
  • Low water level in water system

Data Acquisition and Control Systems also offer various intelligent safety features including programmable channel alarms. Typically you can program the system to activate any number of relays that will open or close fuel lines, control valves, fans or any other device wired to the system.

Fire Suppression

Your Test Cell should have separate fire suppression and alarm system. Since a potential Test Cell fire will be oil, diesel fuel or natural gas in origin, a water sprinkling system will not be effective. Instead a fire suppression system for petroleum product fed fires is recommended. Ensure your system meets the needs of your local fire protection regulations.


Optional guarding is available for securing equipment within your Test Cell which can be specified to the level of safety you require including Air-Starter Guards that completely cover everything within the Test Cell. Chain Systems which secure air hoses and Finger Guards which aid in preventing pinching from the dyno are also available.

Provide Proper Training

Always refer to your Installation & Operations Manuals for safety recommendations on your Test Cell equipment. Provide a safe testing environment by ensuring all employees receive proper training on how to operate the Test Cell equipment including emergency shutdown procedures. Contact your Taylor Dynamometer Service Representative to provide training on best practices, latest advancements, upgrades and even refresher courses as a safeguard to your employees, company and equipment.
