Audible Visual (AV) Notification

System Sensor’s AV notification devices are the most versatile

System Sensor’s AV notification devices are the most versatile, easy to install, and cohesive line of audible visual (AV) notification appliances in the industry. System Sensor greatly simplifies the specification, configuration, and installation of your notification project by providing a plug-in design, aesthetic and functional consistency, and field-adjustable settings across the entire line. Whether for fire alarm systems, emergency communications systems, mass notification systems, general signaling, directional sound, or voice evacuation systems, System Sensor enables you to save time and money while meeting the widest range of notification codes and requirements.

Look for the L-SERIES products in the following subcategories: Accessories, Chimes, Chime Strobes, ECS and MNS, Horns, Horn Strobes, Speakers, Speaker Strobes, and Strobes.

If you're familiar with the SpectrAlert Advance line of AV appliances and would like to know the
L-Series equivalents, review the L-Series/SpectrAlert Advance cross-reference here.

Select a category below to explore.

Chimes

System Sensor Chimes are designed to produce a distinctive chime tone to meet UL 464 private mode applications for alerting trained personnel to investigate possible emergency situations and take appropriate actions. Devices feature rotary switches to select from a multitude of sound patterns and volume settings, and are compatible with 12- or 24-volt systems for additional customization. Using the shorting spring feature to provide instant feedback to ensure that wiring is properly connected – in conjunction with our plug-in design – simplifies the process and cuts install time. Chimes are also compatible with the System Sensor synchronization protocol.

Chime Strobes

System Sensor indoor Chime Strobes were designed to produce a distinctive chime tone to meet UL 464 and UL 1638 in private mode applications, when alerting trained personnel to investigate possible emergency situations and take appropriate actions. Using the shorting spring feature to provide instant feedback to ensure that wiring is properly connected – in conjunction with our plug-in design – simplifies the process and cuts install time. The L-Series offers 7 field-selectable candela settings for wall and ceiling models and 12-or 24-volt operation in one device, chime strobes maximize profits and provide a high level of customization.

Horns

System Sensor Horns increase application flexibility for indoor or outdoor installations. Intended for full building notification as well as on the property ground, they produce a loud sound to notify occupants to evacuate the buildings. Installers can easily adapt devices to suit a wide range of application requirements by using field-selectable sound patterns and volume settings. Compatible with 12- or 24-volt systems. The universal mounting plate’s plug-in design simplifies installation, too. System Sensor horns are listed to UL 464 for public mode application.

Horn Strobes

System Sensor Horn Strobes are rich with features guaranteed to cut installation time and maximize profits. Intended for full building notification as well as on the property ground, they produce a loud sound to notify occupants to evacuate the buildings; the strobe is intended to notify those that may have a hearing impairment. Features include a universal mounting plate with a preliminary snap-in feature to hold the product in place for the screw attachment, 7 field-selectable candela settings for wall and ceiling mount devices, and rotary switches to select horn tone and volume settings. Compatible with 12- or 24-volt systems. Horn Strobes are listed to UL 1971 and UL 464 for public mode evacuation.

Low Frequency Sounders

The SpectrAlert®​ Advance low frequency sounders meet the new NFPA 72® 2010/2013 low frequency (520 Hz) requirements effective January 1, 2014 for sleeping spaces. They include a universal mounting plate with a plug-in design, two sound patterns, 24-volt operation, and are compatible with the System Sensor synchronization protocol.​

Drop-In Ceiling Tiles

System Sensor L-Series Drop-In Ceiling speaker strobes, speakers and strobes install faster than the traditional ceiling speaker or speaker strobe appliances. Neutral grill pattern makes this an excellent option for schools, office buildings, retail, restaurants, and hospital applications.

L-Series makes installation easy. Complete turn-key solution that eliminates the need for a separate back box, extension ring, and suspended ceiling support bracket. Less time working overhead which reduces installer fatigue. No more wasting time routing wires in a crowded junction box to make space for the back of the speaker Perfect fit, the First Time, Every Time. No more adjusting support brackets to get a tight fit between the appliance and ceiling tile. Simplified wiring process, save time and eliminate ground faults. Fast learning curve for new installers or summer helpers supporting school retrofits.

Speakers

System Sensor speakers transmit the clear, intelligible messages necessary to meet code, save lives, and protect property. Indoor, outdoor, wall, and ceiling speakers provide a plug-in design that speeds installation and virtually eliminates costly ground faults. 12- and 24-volt options and the option of plain (non-printed) housings make a single device easily adaptable to a wide range of applications, which simplifies inventory, specification, and installation. Model numbers with a “K” suffix are outdoor-rated, NEMA 4X rated, and listed to UL 1480.

Speaker Strobes

During an emergency, building occupants and those on property grounds need to quickly understand what is happening and what actions to take. System Sensor speaker strobes transmit clear, intelligible messages and visible notification necessary to meet code, save lives, and protect property. In addition, selectable-output speaker strobes offer many features to reduce ground faults and simplify installation. Rotary switches allow installers to select voltage and power, and the 7 field-selectable candela settings for wall and ceiling mounting accommodate any application. Low total harmonic distortion of the SP series line of speakers provides high fidelity and high sound output, making them ideal for use in high-ambient noise environments. The plug-in design and universal mounting plate provides additional flexibility

Strobes

System Sensor Strobes – which are available for indoor, outdoor, ceiling-mount or wall-mount varieties to meet a wide variety of applications – are ideal for warning hearing-impaired individuals during an emergency event. For convenient installation, the universal mounting plate with its snap-in feature holds the product in place for the screw attachment. Strobes feature field-selectable candela settings and are compatible with 12- or 24-volt systems for a high level of customization. System Sensor Strobes are listed to UL 1971 for public mode evacuation. Strobes are available with ALERT printed on the housings for ECS/MNS applications.

Accessories

System Sensor devices can adapt to nearly any application with the appropriate accessory. Our mounting options allow our strobes, speakers, horns, chimes, and strobe combinations to be placed in new or existing construction with professional results.

Our field-applied bezels (AGENT, EVAC, ALERT, FIRE, FUEGO, FOGO, Plain) customize any plain AV device for unique applications. Used in conjunction with our color lenses (amber, red, blue, green), they can turn any strobe into an ECS, general signaling, weather warning, or agent release notification appliance. That means the L-Series line makes it easy for you to expand your business into markets beyond fire.

ECS and MNS
