Audio Samples: AV Tones

Lets you hear all the different audio tones of the AV notification appliances, such as the temporal 3 and non-temporal for the electromechanical, 3.1KHz, 520Hz, as well as the chimes.

Calculator: AV Strobe Coverage

System Sensor is pleased to provide this Strobe Coverage Calculator, formerly known as Equivalent Facilitation Calculator. The calculator was programmed to assist you in the design of audible/visible notification device circuits.

This calculator uses data provided by the user to perform the calculations described in NFPA 72, which permits the use of a performance-based alternative in lieu of tables for spacing ceiling mounted audible/visible devices. These calculations are described in NFPA 72 and are to be provided to the authority having jurisdiction.

To calculate performance-based strobe coverage, the inverse square law is used to calculate the illumination at each of the angles in the horizontal and vertical planes per ANSI/UL 1971, Standard for Signaling Devices for the Hearing Impaired, and the effect of polar distribution is included using the minimum percentages in ANSI/UL 1971 or actual test results recorded by the Listing organization.

The calculated illumination is required to be at least 0.0375 lumens/ft2 at any point within the covered area. The calculation points are in the horizontal and vertical planes in 5 degree increments per UL 1971. For the effect of polar distribution (rated candela at each angle), the ANSI/UL 1971 minimum percentages are used for the calculations. ANSI/UL 1971 does not provide ratings for each angle based on actual test results."

There are no express or implied warranties of any kind with this calculator. System Sensor does not provide any design or engineering services. Users of this calculator are solely responsible for their own selection and use of products based upon information contained in this calculator and any calculations from this calculator. System Sensor shall have no liability.

Calculator: Voltage Drop

Voltage Drop calculations for System Sensor AV products can be done using the Honeywell Online Tools for Fire (HOTFire) site. HOTFire is a free online site that helps users quickly plan and model notification appliance circuits (NACs) using the entire line of SpectrAlert® Advance and L-Series.  Its simple, step-by-step process makes it easy for users to configure panels and circuits from a variety of devices.

Calculator: Sound Pressure Loss
Cross-Reference: AV L-Series to SpectrAlert Advanced

Access a cross-reference document that covers AV notification appliances, from the previous SpectrAlert Advance line to the latest L-Series line. This document contains information on model numbers, descriptions, markings, and lens color.

EASE Evac Software

Our understanding is that EASE® Evac voice evacuation design software from AFMG® Technologies is intended to help designers and installers save time and money on voice evacuation systems by enabling them to preplan the system to meet new intelligibility code requirements, reduce costly post-installation changes, and limit over-design.

Powered by AFMG's proven EASE professional sound design technology, EASE Evac is scaled specifically for life safety professionals and comes preloaded with System Sensor SpectrAlert® Advance speaker data.

System Sensor is not selling, supporting or endorsing AFMG’s EASE Evac voice evacuation software. We are notifying you about EASE Evac as a service to our customers as it may simplify voice evacuation design. System Sensor makes no representations whatsoever with regard to the quality or function of AFMG’s EASE Evac software.


UL 2Wire Capability

System Sensor's product 2-wire compatibility listings are available online for you to view and print out. To view this information, simply choose a manufacturer and the appropriate model. You'll never be more than a mouse click away from the information you need to make informed decisions about our products and their capabilities.

Cross-Reference: Base/OEM Detector Compatibility

Now it's easy to identify System Sensor bases that are compatible with individiual OEM detectors.


PipelQ Software

PipeIQ® is the free all-in-one system design, configuration, and monitoring software for the System Sensor FAAST line of aspirating smoke detectors, including the new FAAST XT. This latest software also includes an enhanced interface for increased ease of use. PipeIQ guides users through the initial pipe layout and system configuration for a FAAST aspiration system.

FAAST Firmware
