DIFFERENT TYPES OF SMOKE ALARMS

Battery operated units: Provide protection even when electricity fails, provided the batteries are fresh and correctly installed. Units are easy to install, and do not require professional installation.

AC powered units: Can be interconnected so if one unit senses smoke, all units alarm. They do not oper- ate if electricity fails. Units must be installed by a qualified electrician.

AC powered units with battery back-up: Can be interconnected so if one unit senses smoke, all units alarm. They will operate if electricity fails, provided the batteries are fresh and correctly installed. Units must be installed by a qualified electrician.

Units for the hearing impaired: Include a visual alarm and an audible alarm horn, and meet the requirements of the Americans With Disabilities Act. BRK® Smoke Alarm model 100S is an AC powered unit that has an 85 decibel alarm and a 177 candela strobe light, which flashes rapidly when the unit is in alarm. These units can be interconnected so if one unit senses smoke, all units alarm. They do not operate if electricity fails. Units must be installed by a qualified electrician.

All these units are designed to provide early warning of fires if located, installed and cared for as described in the user’s manual, and if smoke reaches them.

If you are unsure which type of unit to install, refer to NFPA (National Fire Protection Association) 72 (National Fire Alarm Code) and NFPA 101 (Life Safety Code). National Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Also check your local building codes which may also require specific units in new construction or in different areas of the home.

Smoke particles of varying number and size are produced in all fires.

Ionization technology is generally more sensi- tive than photoelectric technology at detecting small particles, which tend to be produced in greater amounts by flaming fires, which con-

sume combustible materials rapidly and spread quick- ly. Sources of these fires may include paper burning in a wastebasket, or a grease fire in the kitchen.

Photoelectric technology is generally more sensitive than ionization technology at detect- ing large particles, which tend to be produced in greater amounts by smoldering fires, which

may smolder for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.

For maximum protection, use both types of Smoke Alarms on each level of your home.

SC6120B specifications

The BRK electronic SC6120B is a state-of-the-art combination smoke and carbon monoxide (CO) detector designed to provide optimal protection for homes and workplaces. This innovative device is engineered to enhance safety by detecting both smoke from fires and the presence of carbon monoxide, which is often referred to as the "silent killer" due to its odorless and colorless nature.

One of the standout features of the SC6120B is its Voice Alarm system, which emits distinct voice alerts to inform users whether smoke or CO is detected. This audio notification is crucial in emergency situations, as it allows individuals to respond quickly and appropriately. The device also includes a loud, 85-decibel alarm that further enhances alertness in the event of a danger.

The SC6120B utilizes advanced sensing technology to improve detection accuracy. It is equipped with a photoelectric smoke sensor that is known for its rapid response to smoldering fires, which produce smoke without a significant flame. This type of sensor is particularly effective for detecting slow-burning fires, such as those that begin with electrical equipment or household materials. Additionally, the SC6120B has an electrochemical sensor for CO detection, ensuring that it can identify elevated levels of carbon monoxide swiftly.

This unit is also designed for user convenience and reliability. It features a one-button test/hush function that allows users to easily test the unit's functionality or silence false alarms caused by cooking smoke or steam. The SC6120B has a low battery indicator that alerts users when it's time to replace the batteries, ensuring that the device remains operational at all times.

Another remarkable characteristic of the SC6120B is its compact and modern design, making it suitable for various environments, including bedrooms, hallways, and living rooms. It is easy to install, with a battery-operated option that eliminates the need for hardwiring, thus providing flexibility in placement.

In summary, the BRK electronic SC6120B combines innovative features, user-friendly technology, and effective safety detection into one reliable unit. Its dual function of smoke and CO detection, along with its loud alarms and voice notifications, make it an essential device for safeguarding life and property from the dangers of fire and carbon monoxide.
