Abstract

An LCD display unit is attached to the front panel of a typical fire alarm system. The screen displays data (numerical value) pertaining to battery usage in the alarm system. The LCD is connected to the power source (batteries) in the alarm system. A battery icon displayed on the screen shows the user battery power level. Battery icon is fully charged when icon is completely colored (for this example battery will be colored in black). As battery power decreases so does the color of icon from FULL to EMPTY.

LCD FIRE ALARM

Portable alarm systems are used in homes and other buildings to detect smoke in the case of an onset fire. Once it dectects smoke within its vicinity, its sets of a high volume sound as a warning to all those in the area of a possible danger. Most fire alarm systems, especially those in homes, are battery operated and must be tested from time to time to ensure batteries are fully charged and system is operational.

LCDs (liquid crystal displays) are commonly used in portable devices that are battery operated. By reducing the battery consumption of such displays, the portable devices may be used for longer periods of time before a recharge or battery change is required.

Fire alarms save lives everyday. All homes and buildings are equipped with fire alarms and is strictly regulated by state and federal laws. Most fire alarms are battery operated and must be tested from time to time to ensure that it is functional and in working order. To test these fire alarms, the user must press a button on the device. If a sharp tone is emitted, then the user knows the batteries are fully charged and alarm is operational.

Sometimes fire alarms are placed in hard to reach areas. Changing batteries or testing for power failure can be cumbersome and therefore easy to neglect. To help alleviate this problem, employing an LCD on the front of the device would greatly help facilitate testing of fire alarm for power failure. The user can simply read the level of battery power from the display and know whether or not it is time to replace the batteries or not. This quick and easy method of checking for power failure in a fire alarm device would help ensure fire alarms are operational at all times and ultimately increase the safety of those in homes and buildings.

Description of the Invention

An LCD display unit is attached to the front panel of a typical fire alarm system. The screen displays data (numerical value) pertaining to battery usage in the alarm system. The LCD is connected to the power source (batteries) in the alarm system. A battery icon displayed on the screen shows the user battery power level. Battery icon is fully charged when icon is completely colored (for this example battery will be colored in black). As battery power decreases so does the color of icon from FULL to EMPTY.
