Fire alarm control panels (FACP) are systems which receive information from input devices (smoke detectors, heat detectors, etc.), process the information, and trigger an output device such as an audio or visual alarm. Search by Specification | Learn More about Fire Alarm Control Panels

...in one minute. Flashing alarms may consist of a single flash of the lamp, double flash, triple flash, quad flash, or more. Visual alarms that do not flash provide a continuous visual output. The alarm may provide built-in synchronization. NFPA... Search by Specification | Learn More about Warning Lights

Consequently, conductivity can be used to estimate levels of total dissolved solids (TDS), a measurement of the dry mass of dissolved solids in water. As a rule, most of the colloidal particles are included in a TDS measurement. Resistivity, another... Search by Specification | Learn More about Conductivity and Resistivity Meters

Annunciators and graphic display panels disclose the layout and annunciate the status and measurement parameters of industrial processes, security and fire alarms of buildings and manufacturing facilities, power distribution networks, and other Search by Specification | Learn More about Annunciators

...in temperature sensor and a design specially suited for sanitary applications. One special feature is an output of total dissolved solids (TDS). Electrolytes such as acids, bases or salts will increase the conductance of water and other liquids. Thus... Search by Specification | Learn More about Conductivity Electrodes

Photoelectric smoke detectors are better at sensing smoky fires, such that of a smoldering mattress. Smoke detectors have audible alarms, visible alarms such as light-emitting diodes (LEDs), or both. They may also have an alarm output to a control... Search by Specification | Learn More about Smoke Detectors

Tower lights, stack lights and machine lights are used for alarm and machine status indication. They can be supplied with audible alarms and be used as flashers or steady light configurations. Search by Specification | Learn More about Tower Lights, Stack Lights and Machine Lights

Heat detectors are fire detection devices that sense heat produced by combustion. Heat detectors can trigger an alarm when they detect rapid temperature rise or reach a preset temperature. Search by Specification | Learn More about Heat Detectors

...and offer a variety of features. Some gas transmitters include audible or visual alarms, interchangeable probes, on-board data storage, a sampling pump, or a sensor array. Others are intrinsically safe (IS) or designed for use in a hazardous environment... Search by Specification | Learn More about Gas Transmitters

...vary according to tone, frequency, and sound pressure. Some devices have an alarm with a continuous tone, while others have an alarm with a pulsed or non-continuous tone. The frequency measures the number of events or cycles that occur in a time... Search by Specification | Learn More about Audio Transducers and Buzzers
