Installing a Single (Stand-Alone) Alarm (continued)...

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.

Make sure the unit is receiving AC power. Under nor- mal operation, the Green power indicator light will shine continuously.

If the Green power indicator light does not light, TURN OFF POWER TO THE JUNCTION BOX and recheck all connections. If all connections are correct and the Green power indicator still does not light when you restore the power, the unit should be replaced immediately.

INTERCONNECTING MULTIPLE ALARMS

Interconnected units can provide earlier warning of fire or CO than stand-alone units, especially if the incident starts in a remote area of the dwelling. If any unit in the series alarms, all units will alarm.

To determine which Alarm initiated an alarm, see table:

On Initiating Alarms

Red LED(s) Flashes Rapidly

On All Other Alarms

Red LED is Off

All wiring must conform to all local electrical codes and Article 760 of the National Electrical Code (NFPA 70). Refer to NFPA 72, Chapter 2 and/or your local building code for further connection requirements.

Interconnecting Multiple Alarms (continued)...

AC and AC/DC Alarms can be interconnected. Under AC power, all units will alarm when one senses smoke or CO. When power is interrupted, only the AC/DC units in the series will continue to send and receive signals. AC powered smoke alarms will not operate.

Interconnect units within a single family residence only. Otherwise all households will experience unwanted alarms when you test any unit in the series.

Interconnected units will only work if they are wired to compatible units and all requirements are met.

This unit is designed to be compatible with: BRK Electronics® Smoke Alarm Models SC6120B, 4120, 4120B, 4120SB, 4919, 2002RAC, 100S, 5919, 5919TH; BRK Electronics® Heat Alarm Models HD6135F, HD6135FB; BRK Electronics® CO Alarm Models SC6120B; and First Alert® Smoke Alarm Models SA4120B, SA4121B, SA4919B, SA100B.

NOTE: In case of fire or smoke, all compatible

models listed above will alarm. In response to a carbon monoxide situation, only the combination Smoke/CO Alarm will alarm.

Interconnected units must meet ALL of the following requirements:

•A maximum of 18 Alarms may be interconnected. (Maximum of 12 can be Smoke Alarms)

•The same fuse or circuit breaker must power all interconnected units.

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.
