Embodiments of the invention are directed to a release device that uses an electro-mechanical mechanism instead of an explosive to deploy a deployable unit such as a flight data recorder. In one embodiment of the invention, a solenoid is activated that causes a piston surrounded by the solenoid to move which moves a pin attached to the piston and allows a spring to decompress and deploy a deployable unit. In some embodiments, a release actuator mechanism, a pneumatic actuator mechanism, a shape memory alloy or a combination thereof may be used to affect deployment of the deployable unit.
