Description:

First Alert Model SA303 (cat no. SA303B and SA305B) are battery operated single station ionization sensor smoke alarms specifically designed for residential and institutional applications including sleeping rooms of hospitals, hotels, motels, dormitories, and other multifamily dwellings as defined in standard NFPA 101. Model SA303 has been fully tested and complies with, UL217, CSFM, NFPA 72, and NFPA 101 and other agencies that model their codes after the above agencies. They meets building codes where battery operated ionization sensor with silence smoke alarms are required and with model building codes published by the ICC. SA305B meets codes where a removable lithium battery powered alarm is required.

First Alert Model SA303 is a state of the art smoke alarm designed to provide early warning of a fire. It features a dual ionization smoke sensing chamber, an 85dB horn, a supervised 9V carbon zinc battery power supply for cat no. SA303B and a lithium battery power supply for cat no. SA305B, a single button test/silence switch, a silence feature to silence unwanted nuisance alarms, a red LED light that indicates DC power or alarm. It also features tamper resistant locking pins that lock the alarm to the mounting bracket and/or the battery drawer to prevent removal of battery. Battery installation and removal can occur while the unit is mounted to the ceiling or wall via the swing open battery drawer. When battery power drops to a pre-set warning level, the horn will “chirp” approximately once per minute to indicate a fresh battery is needed. Designed for wall or ceiling mounting. Includes mounting anchors and screws. Both cat no.'s are approved for use in recreational vehicles.

SA303B, SA305B specifications

The First Alert SA305B and SA303B are advanced smoke and carbon monoxide detectors designed to enhance home safety and provide peace of mind. These models incorporate cutting-edge technology and user-friendly features, making them essential components of any modern home safety plan.

One of the standout features of both the SA305B and SA303B is the photoelectric smoke detection technology. This technology excels in identifying smoldering fires, which often produce larger smoke particles, making these models particularly effective at minimizing false alarms associated with cooking or steam, common issues in traditional ionization detectors. This capability is crucial for maintaining a safe living environment while reducing unnecessary disturbances.

Another significant characteristic of these detectors is the dual-sensor functionality present in the SA305B model. It combines both photoelectric and ionization sensing technologies to offer comprehensive protection against various types of fires, ensuring quick detection whether the fire is fast burning or smoldering. This dual approach enhances performance and increases the likelihood of early warning in case of fire emergencies.

Both models are equipped with an easy-to-read, low battery indicator that alerts users when it's time to replace the battery. This feature eliminates the guesswork often associated with traditional detectors, ensuring that the units remain operational at all times. The SA305B and SA303B also come with a loud, 85-decibel alarm that provides an unmistakable alert when danger is present, ensuring that all occupants are aware of a potential threat.

Installation and maintenance are straightforward for these detectors. The units come with a user-friendly mounting template and include a test/silence button that allows users to easily confirm operational status. With a sleek and modern design, they fit seamlessly into any home decor while offering vital safety features.

Both the SA305B and SA303B are UL-listed, which means they meet high safety standards set by the Underwriters Laboratories. The expected lifespan for these detectors is around 10 years, after which it is recommended to replace the entire unit. Investing in First Alert's SA305B or SA303B models is a proactive step in ensuring safety from fire and carbon monoxide hazards, making them worthwhile additions to any home.
