A. combination lock bolt and actuator locking bar.
B. cam locking bar and combination lock bolt.
C. locking bolts and combination lock bolt.
*D. actuator locking bar and locking bolts.

A. Security pin assembly
*B. Site activation remote controller (SARC)
C. Secondary door control assembly (SDCA)
D. AC backup generator
- (401) Entering the electromechanical actuator (EMA) system into enhanced maintenance mode is achieved by setting the mode switch on the
A. secondary door control assembly (SDCA) to maintenance only.
*B. SDCA to maintenance and the EMA gearbox safety pin is engaged.
C. site activation remote controller (SARC) to enhanced maintenance only.
D. SARC to enhanced maintenance and the EMA gearbox safety pin is engaged.

A. Swing-out
B. Front
*C. Back
D. Side
- (401) At a [BISMP] LF, it is important to switch the secondary control switch in the security pit control station to OFF before entering the LER because the
A. electromechanical linear actuator (EMLA) would continue operating, possibly damaging equipment.

B. driving the lock cam down.
C. rolling the LC door open only.
D. rolling the LC door closed only.
- (403) The purpose for marking reference points along the launcher closure (LC) rail is to
*A. see if the door is actually moving.
B. allow technicians enough room to safely install the LC barrier set.
C. stop the LC door at certain points to prevent the door from gaining momentum and free-rolling.
