The presently described technology relates to a system having a housing and an optical circuit disposed in the housing. The optical circuit has an emitter configured to emit an emitted optical signal and a receiver configured to receive a received optical signal. An optical transmission pathway extends from the emitter to the receiver. The optical transmission pathway is indirect. A manual actuator is coupled to the housing having an engaged position and a disengaged position. A baffle is fixed to the manual actuator, where the baffle obstructs the optical transmission pathway when the manual actuator is in the engaged position and the baffle is clear of the optical transmission pathway when the manual actuator is in the disengaged position.
