A clip of the beginning of the song "We've Got Work To Do," specifically Zazzalil's refrain "I don't really wanna do the work today" went viral a few months after the musical was released, [9] and was even parodied by the cast of The Book of Mormon. [10]
A main feature of these alarms was the ability to sync them using a System Sensor MDL sync module or the System Sensor sync protocol on a supported fire alarm control panel. Three years after the initial release of the SpectrAlert series, System Sensor released the ceiling mount SpectrAlerts.
A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection. Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system. When used in ...

A fire alarm control panel Fire alarm speaker and pull station. Fire alarm systems are composed of several distinct parts: Fire alarm control panel (FACP), or fire alarm control unit (FACU): This component, the hub of the system, monitors inputs and system integrity, controls outputs, and transmits information.
Smoke detector mounted on a ceiling. A smoke detector is a device that senses smoke, typically as an indicator of fire.Smoke detectors/alarms are usually housed in plastic enclosures, typically shaped like a disk about 125 millimetres (5 in) in diameter and 25 millimetres (1 in) thick, but shape and size vary.
Other alarm levels may be configured to provide fire alarm inputs to fire systems as well as releasing suppression systems. ASD alarm sensitivities are configurable and can be programmed to levels ranging from thousands of times more sensitive than a conventional detector, to much less sensitive. The detectors work best in non-volatile ...
An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, [1] typically as an indicator of fire. [2] They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical [3] or restricted for use by the height of the building.
