	Since these events are irreversible and could be fatal if they occurred at the wrong time or didn't occur at the correct time, NASA went to a significant amount of trouble to ensure that the ELS couldn't be activated accidentally and would operate reliably when it was activated.

			General SECS operation is controlled by switches and circuit breakers on Panel 8 in the Command Module. The logic controls are enabled by moving SECS LOGIC 1 ({{Panel label\|name=A}}) and 2 ({{Panel label\|name=B}}) from OFF to the up position.

			Main power for the SECS is enabled by the nearby SECS LOGIC A ({{Panel label\|name=C}}) and SECS LOGIC B ({{Panel label\|name=D}}) circuit breakers.

			==Launch Escape System==

			{{mainarticle\|Launch Escape System}}

			The Launch Escape System (LES) is responsible for returning the crew safely to Earth in the event of an abort during the launch. If the Launch Escape Tower is still attached to the [[Command Module]] then the escape motor in the tower will be fired to pull the CM away from the Saturn stack, and then after the CM is in a stable situation the [[Earth Landing System]] will take over for an automated landing.
