Monitoring of Communication Lines
2010 code compliance is discussed in this Product Spotlight.
The ASME A17.1/CSA B44 code states that the communication device in the car must have the means to check the “communication” line at least once every 24 hr. As the variety of communication options continues to expand, this becomes more and more difficult to accomplish. Customers with old analog telephone lines are now looking to upgrade to digital, Internet Protocol (IP) or even cellular as their communication means. Also, the days of the U.S. government forcing telephone companies to run analog lines to all these locations have passed.
Rath Microtech has a solution for when a customer requires a means of communication while still under 2010 code requirements. These include analog, digital, IP and cellular communication means. Its standard 2100 series SmartPhone elevator phone, available in numerous mounting styles, can be specified, along with its 2100-Alarm by the fire recall switch. For existing installation with a competitor’s unit, a Rath 2100 series replacement can be substituted.
If the customer has an analog or digital phone line, the standard products listed above are all that are required. More equipment is required for alternative communication methods. For an IP phone line, the 2100-VOIPLC, an IP interface that allows a Rath phone to monitor the customer’s network, needs to be added. (If the network is not accessible, the phone will alarm.) If a cellular plan is decided upon, either Rath’s 2100-CDMALC (for Verizon Wireless) or 2100-GSMLC (designed to accept a SIM card from either AT&T, T-Mobile or a prepaid SIM card) is required. Any of these options can be installed as a standalone phone or complete communication system. Both will work with the company’s SmartRescue and Command Center systems and, it states, meet the exact wording of A17.1/B44.
