Heat Detectors Specifications

Help with Heat Detectors specifications:

Market

	Your choices are...
	Commercial		Devices are designed for commercial applications, such as in an office complex.
	Industrial		Devices are designed for industrial applications, such as on manufacturing floors or within a manufacturing process.
	Residential		Devices are designed for use within private residences.
	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.

Detector Style

	Your choices are...
	Addressable Detector		Addressable detectors communicate within networked detection systems.
	Rate of Rise Detector		Rate-of-rise detectors monitor the rate at which heat increases. They are triggered by a specific rate of temperature increase.
	Fixed Detector		Fixed detectors trigger an alarm at a specific temperature setting.
	Stand-Alone Detector		Stand-alone detectors include a smoke sensor and detector circuitry. Typically, they feature a built-in alarm; however, this is not always the case. Sometimes, instead of built-in alarm, stand-alone detectors have electrical contacts for auxiliary alarms.
	Detection System / Component		Products consist of a smoke detector and control unit, or are smoke detectors that are designed for use in networked systems. These devices are usually programmable.
	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.

Power

	Your choices are...
	AC		Devices operate on AC voltage.
	DC		Devices operate on DV voltage.
	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.
	Operating Voltage Range		The operating voltage range.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

Sensing Technology

	Your choices are...
	Thermoelectric		Thermoelectric detectors use ether a thermistor or thermocouple to measure temperature change. A thermistor is a resistor where the change in resistance indicates a temperature change. A thermocouple measures the voltage change across a metallic conductor.
	Electro-pneumatic		Electropneumatic sensors work by the expansion of gas in a closed container. Changes to the shape of the container trigger a switch.
	Other		Other unlisted, specialized, or proprietary sensing technologies.
	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.
	Detection Temperature		The temperature at which devices are actuated.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Alarm Type

	Alarm Type		Smoke detectors may have audible alarms, visual alarms (LEDs) or both. They may also have alarm output to a control unit. Smoke detectors without a built in alarm come with alarm contacts for output to an external annunciator in the detector base or to a control unit. Smoke sensing ICs may come with piezoelectric horn drivers or with alarm output circuitry. The National Fire Protection Association (NFPA) establishes minimum requirements for fire alarm systems and initiating devices such as smoke detectors. Smoke detectors and fire alarm systems that support NFPA 72 must produce an audible alarm signal that is different from all other audible signals.
	Your choices are...
	Audible Alarm		Devices have an audible alarm.
	Visual Alarm Indicators (LEDs)		Devices may have only visual indicators such as LEDs, or visual alarms and audible alarms.
	Control Panel		Devices communicate a signal to a control panel to trigger the alarm.
	Other		Other unlisted, specialized, or proprietary alarm types.
	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...
	Carbon Monoxide Detector		The assembly includes a carbon monoxide detector.
	Smoke Detector		Smoke detectors are designed to sense the products of combustion. Common types include ionization chambers and photoelectric devices.
	For Use Inside Air Ducts		The device can be mounted inside an air duct.
	Interconnectable		Some detectors or ICs can be connected with other units for common signaling. For these devices, the specifications say "interconnectable" and indicate the maximum number of units that can be connected. Alternatively, the specifications indicate whether the device is suitable for relay connection.
	Adjustable Sensitivity		The sensitivity level which triggers the alarm is adjustable.
	Hermetically Sealed		The contacts are sealed to prevent exposure to explosive or corrosive gasses.
	Wireless		The device uses wireless technology to communicate with an alarm system.
	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.
