Abstract: Devices, systems, and methods for event device maintenance are described herein. In some examples, one or more embodiments include a mobile device comprising a user interface, a memory, and a processor to execute instructions stored in the memory to receive an inventory including a group of event devices, generate a device identification analysis for the group of event devices, display on the user interface the device identification analysis, receive an input for an event device of the group to take an audit action, and initiate the audit action to be taken by the event device of the group in response to the input.

Abstract: Devices, systems, and methods for event input device testing are described herein. In some examples, one or more embodiments include a controller comprising a memory and a processor to execute instructions stored in the memory to cause a first event input device of a group of event input devices to perform an automated test process, and determine whether a second event input device of the group of event input devices has detected a hazard event while the first event input device is performing the automated test process.

Abstract: Devices, methods, and systems of a self-testing duct environment detector are described herein. One self-testing duct environment detector system includes a first portion to be mounted outside of a duct, the first portion having a detector housing with a space therein, the space having a detector with a sensing chamber and a self-testing sensing apparatus therein, wherein the self-testing sensing apparatus determines whether airflow through the detector housing is above a threshold and a second portion and third portion each configured to extend into the duct, wherein the second portion has at least one inlet aperture formed therein and wherein the third portion has at least on outlet aperture therein.

Abstract: Devices, systems, and methods for an alarming system for multi-unit buildings are described herein. One system includes a number of remote sensors positioned in a building having common areas and individual units occupied by occupants, the remote sensors are provided for sensing an alarm condition, a central control panel located in the common areas of the building for collecting data from the remote sensors, the control panel utilized for analyzing the collected data, determining whether to initiate an alarm, and sending one or more signals to initiate an alarm, if an alarm is to be initiated, and an occupant input device located in at least one individual unit for requesting a delay in initiating the alarm.

Abstract: A prefabricated wall panel has a precast body including at least one decorative design element. In addition, the wall panel includes a mounting element having a first end embedded in the precast body and a second end projecting from the precast body. A groove is formed between the precast body and the second end of the mounting element along a first edge of the precast body. A tongue is formed along a second edge of the precast body opposite the first edge. The tongue and groove cooperate to allow prefabricated wall panels to be more easily installed on a support substrate.
