Abstract: In a flat mop cover with an active side to be directed onto a surface to be cleaned and opposite thereto a rear side, transverse edges opposite one another and longitudinal edges opposite one another, wherein the longitudinal edges are longer than the transverse edges and wherein the flat mop cover has on the rear side at least two pockets opposite one another in the transverse direction for receiving a flat mop holder, which extend along the opposite longitudinal edges, it is provided that at least one of the pockets is divided by at least one bar into at least two sections, wherein the bar is adapted and arranged for fixing a predetermined position of the flat mop cover on the flat mop holder.

Abstract: A wetting device for flat mops includes a mechanical elevator that contains a contact structure, brackets, and plastic slide bars. The brackets lift the transfer plate away from the lower end of the wetting device if the contact structure is pressed towards the lower end. Each bracket is connected to at least one plastic side bar. The plastic slide bars move apart from each other when the transfer plate lifts away from the lower end. The transfer plate lies upon the plastic slide bars during movement of the plastic slide bars apart from each other. Each plastic slide bar has a length that is at least five times larger than its maximum width and is detachable from its corresponding bracket. The contact structure is a flat metal framework of connected struts. Also disclosed is a cleaning trolley with the wetting device.

Abstract: A system and method for facilitating user interactions with a life safety system that includes an event panel controller configured to trigger, in response to information received from the one or more life safety system components, an emergency event and insert the triggered emergency event into a queue of active emergency events. The event panel controller is further configured to display an event indication corresponding to the triggered emergency event in an event indicator region of an emergency event graphical user interface (GUI). The event indication is displayed in one of a plurality of event elements of the event indicator region, wherein the one of the plurality of event elements of the event indicator region displays information of the triggered emergency event. Accordingly, each of the event elements remains visible to a user of the event panel controller during its use. Additional embodiments are described herein.

Abstract: An intelligent notification appliance circuit has a controller and one or more addressable notification appliances coupled with a single pair of wires. The controller outputs integrated power, audio and control signals, and transmits the integrated signals to the one or more addressable notification appliances. Thus, the one or more addressable notification appliances are powered, operated, controlled, and monitored using the intelligent notification appliance circuit. When the intelligent notification appliance circuit is implemented in a fire and/or mass notification system, that system is able to provide integrated audio signals, power signals and control signals over a single pair of wires. The integrated audio signals may carry data indicative of live or recorded music and/or voice messages, such as: mass notification messages, general page, voice evacuation, and the like.

Abstract: A system and method for operating a security system include a device control module configured for electronic communication with a plurality of devices and a user interface coupled in electronic communication with the device control module. The user interface includes a voice memory and a first speaker. The user interface is configured to receive a first system event from the device control module identifying a first condition detected by the security system. The user interface is further configured to retrieve a voice message from the voice memory corresponding to the first system event and transmit the voice message via the first speaker.

Abstract: A controller for outputting audio having a predetermined output sample rate. The controller is programmed to receive an audio signal having a first sample rate, identify the first sample rate of the audio signal, select a converter based on the identification of the first sample rate, and convert the sample rate of the received audio signal to the predetermined output sample rate.

Abstract: Property monitoring system and method of operating. Two signal lines are used to couple a master controller in series with a plurality of indicators. Each indicator has a visual display. Each visual display has a plurality of LEDs, or other type of lighting device.
