It shall be identified by a raised symbol and lettering complying with 4.30 and located adjacent to the device. If the system uses a handset then the length of the cord from the panel to the handset shall be at least 29 in (735 mm). If the system is located in a closed compartment the compartment door hardware shall conform to 4.27, Controls and Operating Mechanisms.

The switch marked "ALARM" shall illuminate when actuated. The signaling device shall be located inside the building and audible inside the car and outside the hoist way. One signaling device may be used for a group of elevators. The audible signaling device shall:Have a rated sound pressure rating of not less than 80 dBA nor greater than 90 dBA at 10 ft (3.05 m); Respond without delay after the switch has been activated; Be located inside the building and audible inside the car and outside the hoist way; For elevators with a travel greater than 100 ft (30.48 m), be duplicated as follows: One device shall be mounted on the car; A second device shall be placed at the designated level.
