Abstract

Devices, systems, and methods for displaying an object on a portion of a display are described herein. In some examples, one or more embodiments include a memory and a processor to execute instructions stored in the memory to determine, in response to a fire control panel transitioning from a normal operational mode to a battery backup mode, a scaled object to be displayed on a display panel of the fire control panel, determine, in response to the fire control panel being in the battery backup mode, a modified light emitting diode (LED) backlight setting for the scaled object, and cause the scaled object to be displayed on a sub-portion of the display panel using the modified LED backlight setting.

Description

Technical Field The present disclosure relates to devices, systems, and methods for displaying an object on a portion of a display. Background Facilities, such as commercial facilities, office buildings, hospitals, campuses (e.g., including buildings and outdoor spaces), and the like, may have an event detection system that can be triggered during an event, such as an emergency situation (e.g., a fire) to warn occupants to evacuate. Such an event detection system may include an alarm system having a control panel and a number of event devices (e.g., sensors, sounders, pull stations, etc.) located throughout the facility (e.g., on different floors and/or in different rooms of the facility) that can perform an action when an event (e.g., a hazard event, a fault event, etc.) is occurring in the facility. In an example of an event, the number of event devices may provide a notification of the event to the occupants of the facility via alarms and/or other mechanisms. Brief Description of the Drawings Figure 1 is an example of a system for displaying an object on a portion of a display, in accordance with one or more embodiments of the disclosure.Figure 2 illustrates an example of a fire control panel having a representation of a scaled object displayed on a display panel during a battery backup mode, in accordance with one or more embodiments of the disclosure.Figure 3 illustrates an example of a fire control panel displaying a scaled object on a display panel during a battery backup mode, in accordance with one or more embodiments of the disclosure.Figure 4 is an example of a controller for displaying an object on a portion of a display, in accordance with one or more embodiments of the disclosure. Detailed Description Devices, systems, and methods for displaying an object on a portion of a display are described herein. In some examples, one or more embodiments include a memory and a processor to execute instructions stored in the memory to determine, in response to a fire control panel transitioning from a normal operational mode to a battery backup mode, a scaled object to be displayed on a display panel of the fire control panel, determine, in response to the fire control panel being in the battery backup mode, a modified light emitting diode (LED) backlight setting for the scaled object, and cause the scaled object to be displayed on a sub-portion of the display panel using the modified LED backlight setting. A facility can utilize an event detection system in order to warn occupants of the facility of an emergency event, such as a fire. An event detection system can be a system of devices that operate to collect information about a facility and provide the collected information for analysis. Such an event detection system can also take actions based on the collected information, such as providing an audible and/or visible warning in an emergency event. For example, the event detection system can utilize event devices to warn occupants of an emergency event occurring in a space, such as a fire. As used herein, the term "event device" refers to a device that can receive an input relating to an event and/or generate an output relating to an event. Such event devices can be a part of the event detection system of a space in a facility/in the facility at large and can include devices such as fire devices including fire sensors, smoke detectors, heat detectors, carbon monoxide (CO) detectors, or combinations of these; fire control panels; air quality sensors; interfaces; manual call points (MCPs); pull stations; input/output modules; aspirating units; fire doors; and/or audio/visual devices (e.g., speakers, sounders, flashers, buzzers, microphones, cameras, video displays, video screens, etc.), relay output modules, among other types of event devices. Such event devices may also include self-test capabilities. In an event detection system, a control panel, such as a fire control panel, can utilize a display panel in order to display information to a user. For example, the display panel can display information relating to event devices in the system such as their status, whether any events are occurring, etc. If an event occurs, the display panel can display information relating to the event, such as the type of event, the event device that detected the event, the location of the event device, etc. During normal operation of the control panel, the control panel can be powered by a power mains. For instance, an alternating current (AC) mains can provide power to the control panel during normal operation. However, in an instance in which the AC mains to the control panel is lost, the control panel can operate in a battery backup mode. While in the battery backup mode, a battery can provide power to the control panel to enable the control panel to continue to operate. For example, the control panel can communicate (e.g., transmit and/or receive information) with event devices in the facility and/or with remote compu
