Description:

The BRK Brands, Inc. Cat. Nos. 9120 and 9120B are wire-in, 120V AC 60Hz single and/or multiple station smoke alarms specifically designed for residential and institutional applications including sleeping rooms of hospitals, hotels, motels, dormitories and other multi-family dwellings as defined in standard NFPA 101. Models 9120 and 9120B comply with UL217, CSFM, NFPA 72, HUD, FHA and other agencies that model their codes after the above agencies. They meet building codes where AC and AC/DC with Silence smoke alarms are required. The alarms are interconnectable with up to 18 devices, of which 12 can be smoke alarms.

The BRK® 9120 Series alarms feature a dual ionization smoke sensing chamber - screened for insect protection, an 85dB horn, 9V battery back-up (all versions except model 9120) and a “silence” feature. The “Smart Technology” system is designed to reduce nuisance alarms. “Latching Alarm Indication” remembers which unit initiated an alarm. When interconnected in a series, the unit that triggered the alarm rapidly flashes its red LED indicator. After the alarm condition subsides, the initiating unit will store in memory or “latch” the information and begin to flash the green LED indicator 2 seconds on, 2 seconds off. The “Perfect Mount” system features a gasketless base and a mounting bracket that keeps the alarm secure over a wide rotation range to allow for true alignment. This will allow fine-tuning on the positioning to compensate for out of aligned wall studs and to keep the wording level when wall mounting. A Single button test/silence button eliminates confusion. Depending on what mode the alarm is in, pushing the button will test, silence, re-test the alarm when in silence and clear the latching feature. Battery installation and removal can occur while the unit is mounted to the ceiling or wall via the side load battery compartment. Other Contractor

Preferred features include a dust cover to keep alarm clean during construction, keyhole slots in the mounting bracket eliminate the need to remove the electrical box screws for installation. Two locking features are provided to

prevent battery theft and/or theft of the unit. Connection to AC power is made with a “Quick-Connect” wiring harness. Installa-

tion is quick, easy and cost effective.

9120 Series specifications

The BRK Electronic 9120 Series is a pivotal line of smoke detectors designed to ensure safety and peace of mind in residential and commercial environments. Known for their reliability and advanced technology, these smoke detectors stand out in the market, highlighting essential features that cater to the diverse needs of users.

One of the standout characteristics of the BRK 9120 Series is its dual-sensor technology, which integrates both photoelectric and ionization sensing methods. This combination allows for a more comprehensive detection of various types of smoke generated by different fire sources. While the photoelectric sensor excels at detecting smoldering fires (often associated with household materials like upholstery), the ionization sensor efficiently identifies fast-flaming fires. This dual-sensor capability provides enhanced protection, ensuring that alarms trigger in a broader range of fire scenarios.

Another notable feature of the 9120 Series is its hardwire connectivity with a battery backup. This ensures that the detectors remain functional even in the event of a power outage, a critical consideration during emergencies. The interconnected design allows for multiple units to communicate with each other; when one alarm detects smoke, all interconnected units will sound, alerting everyone in the vicinity.

The BRK 9120 Series also incorporates a convenient silence feature, helping to reduce false alarms caused by common cooking scenarios or accidental triggers. Users can quickly silence the alarm while remaining confident that it will still function correctly in the event of an actual emergency.

In terms of maintenance, the 9120 Series is designed for easy battery replacement and unit testing. Its compact design and user-friendly interface make it accessible for individuals of all ages to manage effectively. Many models feature a built-in safety light that illuminates when the unit is powered and operating correctly.

Additionally, the BRK Electronic 9120 Series is equipped with a low-battery alert that notifies users when it’s time for a battery replacement, enhancing overall reliability. Furthermore, these detectors meet rigorous safety standards and often come with a five to ten-year limited warranty, providing users with confidence in their investment.

In summary, the BRK Electronic 9120 Series exemplifies modern smoke detection that prioritizes user safety and convenience. With its dual-sensor technology, hardwire capabilities, ease of maintenance, and interconnected systems, it remains a top choice for ensuring the safety of homes and businesses alike.
