A building management system of an occupiable structure with an elevator system includes an elevator video display, a building computing device and a building status system. The building computing device includes a computer processor and a computer readable storage medium. The building status system is configured to send real-time building condition signals to the building computing device, and the building status system is configured to process the real-time building condition signals and output an associated information signal for display on the elevator video display.

Building management system integrated with elevator display

A communication gateway device to facilitate communication between at least one elevator car, a call center system, and a third party device includes a cellular communication interface including a digital cellular interface and an analog cellular interface, a wired telephone communication interface including a digital wired telephone interface and an analog wired telephone interface, and an elevator communication interface to send and receive an elevator communication to and from at least one elevator communication device associated with the at least one elevator car, the elevator communication interface associated with the cellular communication interface and the wired telephone communication interface to send and receive the elevator communication to and from at least one of the call center system and the third party device via at least one of the digital cellular interface, the analog cellular interface, the digital wired telephone interface, and the analog wired telephone interface.

Elevator communication gateway

A method for downloading software includes transmitting only that portion of the program which is to be updated or otherwise changed. In a preferred aspect, a key is also transmitted which must match a key last stored in EEPROM, to permit the download to be effected.

Method for replacing software modules utilizing a replacement address

A master data processor (18) may send data indicative of equipment condition through a modem (24) to a modem (26) of a data processor (28) in a local monitoring center (over telephone lines) whenever they occur in response to a seize mode (59) or between established times of day (64, 68, 69), or whenever the telephone line becomes free (65)if the data messages amount to alarm conditions (65). Calls can be received at the local monitoring center 14 between said preestablished times (79-82) after a predetermined number of rings (83, 85).

Remotely programmable equipment monitoring telephone line protocol

After receiving an answer tone from a receiver modem, a sender modem transmits a series of DTMF pulses of predetermined tone, duration, and spacing. If the receiver modem does not verify that the pulses have the correct tone, duration and spacing, it simply hangs up.
