Disclosed are an alarm method and apparatus for a digital enhanced cordless telecommunications (DECT) terminal, and a storage medium. The method includes: when an alarm function of the DECT terminal is triggered, recording an account of the DECT terminal, matching an emergency contact based on the account of the DECT terminal, and establishing alarm communication with the emergency contact; and after establishing the alarm communication between the DECT terminal and the emergency contact, sending location information of a network base station connected to the DECT terminal to a device of the emergency contact, such that the device of the emergency contact obtains an alarm call of the DECT terminal and displays the location information of the network base station connected to the DECT terminal.
摘要:
During operation of the door system one or more sensors may be utilized in order to monitor the operation of the door assembly (e.g., door system, door, frame, etc.), review the operating parameters, troubleshoot potential issues, schedule and monitor service requests, review and take actions for potential security threats, and/or the like. Consequently, users may determine if the door system operates the door in accordance with the desired operating parameters by reviewing the movement, vibration, speed, acceleration, force, or the like based on the sensor information captured and use the information to adjust the door assembly. Notifications regarding the operation of the door systems may be sent automatically and/or in response to requests from users. The users may utilize one or more applications and interfaces thereof to remotely connect to the door systems in order to review and analyze the sensor information and take the desired actions.

An apparatus, system and method for quickly and simply providing non-duplicative addresses for addressable devices on a communication channel or network. The system contains at least one system controller communicating with at least one addressable device on at least one communications channel or network. Preset address elements configured in a mating connector arrangment or as an adhesive label provide unique addresses to each of the addressable devices. The preset address elements may use digital or analog circuit techniques to encode unique addresses that are subsequently read and stored by the addressable devices. When installed, the preset address elements also provide visual indications of the device addresses.
摘要:
An intruder alarm system includes a number of sensors each of which comprises first and second series-connected resistances and a sensor switch connected in parallel with the first resistance. The first resistances of each sensor are different in value from one another, but their values are related in a known manner. The sensors are connected in series with one another by a connecting cable and to a constant current source. The voltage developed across the series-connected sensors is applied to a circuit arrangement operable to offset the effect of the total resistance of the second resistances of each sensor and of the connecting cable. An analogue-to-digital converter is responsive to the output of the circuit arrangement to deliver a digital output to an indicator which indicates the actuation of any sensor.
