I need some assistance understanding ASME 17.1 2010 with regard to signaling/communication requirements.
Otis Traction elector, 5 story building, built in 1929.
An emergency telephone has been installed according to code, which will operate even when power is out.
The elevator also has it's original push-to-sound alarm bell button, which operates on normal power (no battery backup).
So the question is this:
Given that the emergency phone is there, does the alarm bell button need to be hooked up to battery backup?
My reading of the code suggests not, but I need a second opinion.
Here is what Item 1.6 of ASME 17.2-2010 guide says:
"Elevators installed under A17.1-1955 through
A17.1b-1980, which are operated without a designated
attendant, must be provided with an emergency signal
audible outside the hoistway, or with a telephone.."
