Interconnecting Multiple Alarms (continued)...

•The total length of wire interconnecting the units should be less than 1000 feet (300 meters). The interconnect wire should be #18 gauge or larger, rated at least 300V.

•If an interconnect wire is not already part of your household wiring, you will need to install one. This type of wire is commonly available at Hardware and Electrical Supply stores.

Failure to meet any of the above requirements could damage the units and cause them to mal- function, removing your protection.

1.Remove mounting bracket from the base. Position screw slots on mounting bracket over screws in the junction box. Tighten screws.

2.Strip off about 1/2” (12 mm) of the plastic coating on the white/gray stripe wire on the power connector.

3.Using wire nuts, connect the power connector to the household wiring.

•Connect the white wire on the power connector to the neutral wire in the junction box.

•Connect the black wire on the power connector to the hot wire in the junction box.

•Connect the white/gray stripe wire on the power connector to the interconnect wire in the junction box. Repeat for each unit you are interconnecting.

4.Plug power connector into the back of the Alarm.

5.Position the base of the Alarm over the mounting bracket and turn. The Alarm can be positioned over the bracket every 60°. Turn the unit clockwise (right) until the unit is in place. NOTE: For Wall Mounting, position the battery drawer, marked “THIS SIDE UP”, so it faces the ceiling.

ELECTRICAL SHOCK HAZARD. Do not restore power until all Alarms are completely installed. Restoring power before installation is complete may result in serious electrical shock, injury or death.

6.Make sure each unit is receiving AC power. Under normal operation, the Green power indicator light will shine continuously.

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.
