Why should you use the LX switch with an ALK being used in Von Duprin surface vertical rod devices?

You should use the LX switch with the Von Duprin surface vertical rod exit device because the rods are exposed and are vulnerable to attack. IE, the top rod can be grasped and forced down to retract the top and bottom latches and bypass the alarm.  The standard RX switch only monitors the pushbar movement.
