The Timed Release Restraint System, or TRRS, starts with a high-quality electromagnet rated for 600 pounds holding force. It’s powered by half an amp of current at 12 volts, and sets up as a positive fail system. That is, when the timer expires OR the power goes out, it releases. It’s also simple enough to rig an emergency release using a length of cord to disconnect power.
The strike plate — a steel bar that the magnet holds in place — incorporates a spring-loaded button that ensures a positive disconnect and a welded steel eyebolt attachment point. Complete the system with a 12V power supply and a method of timing your release… the TRRS can be powered and controlled directly from the SOM2PC control system, sharing the main SOM 12V supply, or released using any wall timer and a 12V wall wart. Note that the timer and small power supply shown in the picture are no longer included in this package.
There are several effective ways to use the TRRS. It was initially designed for use with the SOM II Bench, and works perfectly with that system. It’s also flexible enough for use wherever you’d like, either as a direct restraint point or a very accurate key release. All SOM2PC systems ship with hardware preconfigured to run the TRRS, allowing timed release controlled by the computer.
