Two-Way Voice Communication in Passenger Elevators and Vertical Platform Lifts

 

Date: 9-12-2017

 

Background

 

This document describes the Wisconsin Administrative Code requirements for telephones in passenger elevators and vertical platform lifts in buildings other than single or two-family dwellings. It is intended to address the most common issues such as whether a two-way voice communication device is required, the type of device that is required, how the device is to make calls and how and where calls are to be answered.

 

Requirements for communication in elevators and lifts have changed considerably over the years due to changes in the adopted national standards often as a result of changes in technology. Codes have also changed in response to cases of passenger entrapments and increased recognition of the needs of the elderly and persons with disabilities when using elevators and lifts without assistance.

 

 

Applicable Wisconsin Administrative Codes and Statutes

 

Wisconsin DSPS Administrative Code Ch. SPS 318, Elevators, Escalators and Lift Devices.

 

Previous DSPS, Comm (Dept. of Commerce), ILHR (Dept. of Industry, Labor and Human Relations) and Ind (Industrial Commission) codes in effect when the elevator, platform lift or two- way communication device was installed.

 

Adopted ASME A17.1 / CSA B44 Safety Code for Elevators and Escalators - currently the 2013 edition (referred to here as A17.1).

 

Adopted ASME A18.1 Safety Standard for Platform lifts and Stairway Chairlifts - currently the 2011 edition.

 

Adopted ICC / ANSI A117.1 American National Standard for Accessible and Usable Buildings and Facilities – currently the 2003 edition.

 

Current Requirements

 

Note: These are the current requirements. Codes in effect at the time a means of signaling or communication was installed in an elevator or lift may differ. See the code in effect at that time. A partial list is in Appendix A.

 

The adopted A17.1, section 2.27.1 addresses two-way communications. Most of the A17.1 code is written in prescriptive language, including the code requirement and how it is to be measured or achieved. The section of the code addressing emergency communications is written in performance language, that is, it describes the required outcome but not necessarily how it must be achieved.

 

The national standard in effect for accessible and usable buildings and facilities is the ICC / ANSI A117.1. This includes additional requirements for use of buildings and elements by persons with a wide range of abilities.   If there is a system or device that can meet the requirements of both the A17.1 and the ICC / ANSI A117.1, the system or device may be used. The requirements have changed over the years with the current requirements summarized as follows (see each code section referenced for exact code language and details):

 

  1. The device must be activated by one push button. The device may not use a handset.

A17.1, 2.27.1.1.3 (b) and (g)

 

 

  1. Accessing or operating the button must be performed using one hand without requiring tight grasping, pinching or twisting of the wrist. The force required to activate shall be 5.0 lbs maximum. Note: At one time elevator telephone cabinets having a heavily spring-loaded door with a very small handle were common. This requirement prohibits locating a new emergency telephone in a cabinet with such a door.

ICC / ANSI A117.1, 309.4.

 

 

  1. The button must be located in or adjacent to the car operating panel. The highest operable part must be between 35" and 48" above the elevator or vertical platform lift floor.

A17.1, 2.27.1.1.3 (b) and ICC / ANSI A117.1, 407.4.10.1.

 

 

  1. The button must be identified as "PHONE" using tactile characters and symbols. Operating instructions must be included.

A17.1, 2.27.1.1.3 (b) and (i) and ICC / ANSI A117.1, 407.4.10.2.

 

 

  1. Actuating the device must initiate a call for help and establish two-way voice communication with authorized personnel who can take appropriate action. The device may not reach an answering system.

A17.1, 2.27.1.1.2 (a) and 2.27.1.1.3 (b) and (h).

 

 

  1. If the device does not reach authorized personnel within 45 seconds, the call must automatically be directed to another on- or off-site location to reach authorized personnel.

A17.1, 2.27.1.1.2 (b).

 

Note: By combining the information in 5). and 6)., it is acceptable for the device to reach an automated system as long as the device reaches authorized personnel within 45 seconds.

 

  1. The two-way voice communication means must provide the authorized personnel with the location of the building, the elevator (or lift) number (or location) and a request for assistance. Note: This is typically on a message recorded in the telephone and played for the authorized personnel once the call is answered.

A17.1, 2.27.1.1.3 (d).

 

 

  1. The authorized personnel must activate a visual indication on the "PHONE" panel in the elevator or platform lift acknowledging that the call has been established. Note: This is mainly for the benefit of the hearing impaired.

A17.1, 2.27.1.1.3 (c).

 

 

  1. After the call has been established and the acknowledgement sent to the car or platform, two- way voice communication shall be available between the car or platform and the authorized personnel.

A17.1, 2.27.1.1.3 (e).

 

 

  1. The two-way voice communications shall be ended only when the authorized personnel terminate the call or after a minimum of 3 minutes.  See this section for details.

A17.1, 2.27.1.1.3 (f).

 

 

  1. The visual indicator described in 8). above may be extinguished only after the two-way voice communication is terminated.

A17.1, 2.27.1.1.3 (c).

 

  1. For elevators only (not required for vertical platform lifts) a means shall be provided to verify the operability of the means of two-way voice communications. The verification must occur automatically and at least daily.

A17.1, 2.27.1.1.6 and SPS 318.1802(10)

 

 

13 a). For elevators having travel of less than 60 feet and for vertical platform lifts, any need to re-establish two-way voice communication once a call has been terminated is only required to be available to persons in the elevator or lift.

 

13 b). For elevators having travel of 60 feet or more, a means must be provided for emergency personnel within the building to establish two-way voice communication to each elevator individually. This must occur without action by a person in the elevator. This must override attempts by a person in the elevator to re-establish two-way voice communication to authorized personnel outside the building.

A17.1, 2.17.1.1.4

 

Note: The 60 foot travel is an important distinction. For elevators and platform lifts described in 13 a), there is no requirement for a means to call back into the elevator or platform lift. If two- way voice communication is to be re-established, it is only required to be re-established by a person in the elevator or lift. This makes use of a line-seizure device or similar switching system more likely to comply and makes a dedicated telephone line for the elevator or lift (and associated cost) less likely to be necessary.

 

For elevators described in 13 b). with travel of 60 feet or more, the need to provide a means for personnel on-site to re-establish voice communication to each elevator may require dedicated telephone lines or other switching means or equipment to allow establishing two-way communication.

 

Also note, the 60 foot travel limit is not affected by the number of stories or the location of the stories related to grade level for the building or structure. Travel is measured from the lowest landing served to the uppermost landing served.

 

14). If the means of two-way voice communication is powered by building power, not by telephone line power, the device must transfer to an alternate power supply after normal power fails. Power must be provided to operate the visual indicator addressed in 8) above and the means of two-way voice communication for at least 4 hours.

 

Note: Codes do not prohibit the use of any particular type of technology. Cellular, VoIP (Voice over Internet Protocol), PBX (Private Branch Exchange), satellite and other technology may be used as long as it meets all the above requirements listed in 1 through 14 and the codes the list is based on.

 

 

Authorized Personnel for Answering Passenger Elevator or Vertical Platform Lift Calls

 

Telephones in elevators and vertical platform lifts to reach persons trained to take appropriate action in an emergency.

 

In Buildings With 24-Hour Staffing

 

In buildings where authorized personnel are trained to respond to an emergency in an elevator or vertical platform lift at any time (24 hours/day, 7 days/week including holidays), calls are required to reach those trained individuals. Such authorized personnel are common in hospitals (information desk or building superintendent for example), nursing homes (nurse's station), hotels (front desk), some office and apartment buildings (security desk) and college campuses and other campuses (campus police or campus security).

 

 

In Buildings Without 24-Hour Staffing

 

In buildings that do not have authorized personnel on site 24 hours/day, 7 days/week including holidays, calls from elevators and vertical platform lifts must reach someone trained to take appropriate action in an emergency. By definition, after hours calls must go to authorized personnel off-site, commonly to a telephone answering service, security company or elevator company.

 

Elevator or platform lift calls may not go only to an individual or telephone number affiliated with the owner or the organization for multiple reasons.

 

  1. Individual(s) often at that number may be unavailable at times. This has been suggested where a church has a pastor, caretaker or trustee willing to take such calls. This has been suggested where an apartment building or other building has an on-site or off-site manager. Also, an individual intending to be available 24/7 via a personal cellular telephone or with call forwarding may not always be available, may not have cell service everywhere or may have a discharged battery.

 

  1. The individual expected to answer all calls from the elevator or lift telephone may be the one stuck in the elevator or lift after hours.

 

  1. An individual not part of an answering service may be pre-occupied and unable to locate the appropriate elevator personnel to respond appropriately to the call. Code requires the individual answering the call to be able to take appropriate action immediately.

 

 

911 or Other Local Emergency Service as Authorized Personnel

 

A local police or fire department may with permission accept calls from elevator or platform lift emergency telephones. Many local services may accept such calls while others may have an ordinance or policy prohibiting such calls. Permission to direct calls to the local emergency service would include the number the service would require the call to go to. In some communities, calling 911 from an elevator or lift telephone may be a misdemeanor and subject to fines or other penalties.
