When the A17 Code was amended to include Section 220.127.116.11.6, stating the elevator phone must check the telephone line at least once every 24 hours, it was written around a standard analog line. In the 2015 version of the code they state that if you are utilizing a line other than analog the phone must function in a similar manner.
We developed our SmartPhone to initially work on an analog line and then expanded that to include Digital, VoIP, and RATH® Intercom Systems. Now we have this technology available with a Cellular Line, either CDMA or GSM. Our phone, in conjunction with our Cellular Interface, will monitor the Cellular Network and if it detects the network is unavailable it will cause the same emergency communication failure trip we provide today.
The wording for the Emergency Communication Device adopted into the 2010 version of the A17 and B44 Elevator Codes is as follows:
(a) The two-way communications means within the car shall include a means to verify operability of the telephone or communication line, where:
1. Verification of the telephone line operability shall be automatically performed.
2. Verification may be continuous or periodic.
3. Periodic verification shall be at least on a daily basis.
4. Verification shall not require activation of the two-way communications. If means other than a telephone line (e.g., VOIP, network, intercom, etc.) is used for the two-way communications, similar verification of this equivalent means shall be performed.
If the phone line is disconnected or is non-functioning for any reason, our 2100-ALARM will provide an audible and visible indicator that the phone isn’t working so maintenance staff can quickly restore communication.
RATH® Phones, along with the 2100-ALARM, can monitor Analog and Digital phones.
