Alarm Types and Applications


	Zones / Alarm Points (IDCs)		This refers to the number of zones or alarm points covered by the alarm or annunciator. Zones are groups of initiating devices wired on a common circuit. Each wiring circuit is used to relay information to the panel regarding the condition of the initiating devices, which can include smoke, heat, or fire detectors, manual pull stations, or any circuit closure device.

	Switches / Relays		The control output is a change in state of a switch or relay.
	Serial Interface		Serial interface outputs are transmitted one bit at a time via a standard digital protocol such as RS232, RS422, or RS485, etc.
	Transmitters		Transmitters connect initiating devices or groups of initiating devices. The component transmits signals to the central supervising station, indicating the status of the initiating devices and the initiating device circuits. These may include remote station transmitters or municipal box transmitters.
	DACT		Digital alarm communicator transmitters (DACT) seize the connected telephone line, dial a preselected number to connect to a digital alarm communicator receiver (DACR), and transmit signals indicating a status change of the initiating device.

	Compressed Air		The alarm is powered by compressed air. Air horns are a common alarm type that uses compressed air.
	Manual Operation		The alarm is operated only by manual operation, such as a crank or push-button.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Mounting and Features


	Mounting		Manufacturers use many of these terms interchangeably. Keeping this in mind, we have delineated the options as follows to help you locate the ideal item(s) for your needs.
	Your choices are...
	Adhesive / Magnetic Base		The device has a self-adhesive or magnetic base. It is designed to be glued / adhered to surface.
	Chassis / Rack / DIN Rail		Chassis mount devices can be attached to, or within, the supporting frame of a structure (chassis), exclusive of the body or housing. Some chassis varieties can be mounted within a rack. Rack mount units can be mounted directly into a rack. They come equipped with the necessary rail guides, flanges, or tabs to be mounted in this fashion. The standard 19" rack is typical of this style. DIN rail devices can be mounted on a standard DIN rail.
	Flange Mount		The device is equipped with integral flanges so that it can be mounted with the use of external hardware (screws, bolts, rails, etc.).
	Stand Alone / Freestanding		Stand alone devices do not need to be mounted; they can stand on its own.
	Handheld / Portable		Handheld or portable devices are designed to be moved freely; they are not meant to be bolted or hardwired in place. This style can include items with wheels, briefcase, laptop style, or handheld products.
	Flush Mount		The device can be placed into, or through, a depression within an existing panel so that it's face is flush, or nearly flush, with the panel, wall, or ceiling. The method of attachment may include screws, bolts, rails, flanges, etc.
	Pole Mount		The alarm is supplied with brackets for installation on a vertical pole.
	Other		Other unlisted, specialized, or proprietary configuration.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Features
	Your choices are...
	Acknowledge / Silence		The "acknowledge" feature allows the operator to mute the audible alarm while maintaining some visual alarm indication.
	Battery Back-up		The unit has back-up batteries in case of power failure.
	Data Logging / Event Logging		The unit can store data for subsequent download to a host PC or monitor for viewing.
	Explosion Proof		Explosion-proof devices have totally enclosed housings that are constructed to withstand internal explosion of a specified gas, vapor or dust. If an explosion occured, the enclosure would prevent the ignition or explosion of the gas or vapor surrounding the motor enclosure. Underwriters Laboratories (UL) governs several explosion-proof ratings.
	Intrinsically Safe		Intrinsically safe (IS) is an adjective for equipment and wiring that is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture in its most ignited concentration. The IS terminations and wiring may be brought into any hazardous location of any group classification for which it is accepted without requiring explosion proof housing or other means of protection.
	Voice Evacuation		Voice evacuation alarms are manual or automatic supervised paging systems used to transmit a voice message (such as information, instruction, direction) on a selective and all-call basis.
	Outdoor Rated / Weatherproof		The device is designed to function normally in an outdoor environment. It is, to varying degrees, sunlight, water, temperature, frost and ice, etc., resistant.
	PC Interface		The unit is capable of PC interface via Windows® software.
	Programmable		The device provides output coding or it is programmable or adjustable to provide for different ranges, materials, levels, outputs, etc.
	Remote Phone Enabled		The alarm or annunciator can be controlled remotely via telephone interface.
	Selectable Candela		The unit allows users to choose between several pre-specified levels of candela, or light intensity.
	Submersible		Submersible devices are designed to function optimally while underwater.
	Synchronization		The alarm, annunciator, provides built-in synchronization of audible signals or strobes. NFPA 72 requires visual appliances to flash in synchronization in rooms or areas where there are two or more visual devices that are not a minimum of 55 feet apart. NFPA 72 requires that fire alarm signals be distinctive in sound from other signals and used for that purpose only. This is known as the three-pulse temporal pattern.
	System Test		The system is capable of self-testing.
	Volume Control Option		The alarm contains an adjustable volume control.
	Web Enabled		Device contains hardware and software protocols such as Hypertext Transfer Protocol (http) or Web Access Protocol (WAP) for being addressable to, or a node of, the World Wide Web for remote monitoring or communication.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
