Using the Optional Locking Features

The optional locking features are designed to discourage unauthorized removal of the battery or alarm. It is not necessary to activate the locks in single-family households where unauthorized battery or alarm removal is not a concern.

These Smoke/CO Alarms have two separate locking features: one locks the battery compartment, and the other locks the Smoke/CO Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.

Tools you will need: • Needle-nose pliers or utility knife

• Standard/Flathead screwdriver.

Battery Drawer Lock

Locking Pin

Mounting Bracket Lock

Both locking features use locking pins, molded into the mounting bracket. Using needle nose pliers or a utility knife, remove one or both pins, depending on which locking features you use.

THE BATTERY COMPARTMENT LOCK

TO LOCK THE BATTERY COMPARTMENT:

Do not lock the battery compartment until you have activated the battery and tested the battery back-up.

1. Activate the battery back-up by removing the “Pull to Activate Battery Back-Up” tab. Push and hold the test button on the Smoke/CO Alarm’s cover until the alarm sounds: 4 beeps, pause, 4 beeps, pause, 3 beeps, pause, 3 beeps, pause.

If the unit does not alarm during testing, DO NOT lock the battery compartment! Install a new battery and test again. If it still does not alarm, replace the Smoke/CO Alarm immediately.

2. Using needle-nose pliers or a utility knife, detach one locking pin from the mounting bracket.

3. Push the locking pin through the black dot on the label on the back of the Smoke/CO Alarm.

TO UNLOCK THE BATTERY COMPARTMENT:

Once the Smoke/CO Alarm is installed, you must disconnect it from the AC power before unlocking the battery compartment.

ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke/CO Alarm is installed before removing it from the mounting bracket. Failure to turn off the power first may result in serious electrical shock, injury or death.

1.Remove the Smoke/CO Alarm from the mounting bracket. If the unit is locked to the bracket, see the section “To Deactivate the Locking Feature.”

2.Disconnect the power connector by gently prying it away from the back of the Smoke/CO Alarm.

3. Insert a flathead screwdriver under the head of the locking pin, and gently pry it out of the battery compartment lock. (If you plan to re-lock the battery compartment, save the locking pin.)

4. To re-lock the battery compartment, close the battery door and reinsert the locking pin in the lock.

5.Reconnect the power connector to the back of the Smoke/CO Alarm, reattach the Smoke/CO Alarm to the mounting bracket, and restore the power.

When replacing the battery, always test the Smoke/CO Alarm before re-locking the battery compartment.

THE MOUNTING BRACKET LOCK

TO ACTIVATE THE BRACKET LOCK:

1.Using needle-nose pliers, detach one locking pin from the mounting bracket.

2.Insert the locking pin into the lock located on the base as shown in the diagram.

3.When you attach the Smoke/CO Alarm to the mounting bracket, the locking pin’s head will fit into a notch on the bracket.

TO DEACTIVATE THE BRACKET LOCK:

Always discharge the branch circuit before servicing an AC or AC/DC Smoke/CO Alarm. First, turn off the AC power at the circuit breaker or fuse box. Next, remove the battery from Smoke/CO Alarms with battery back-up. Finally, press and hold the test button.

1.Insert a flathead screwdriver between the mounting bracket pin and the mounting bracket.

2.Pry the Smoke/CO Alarm away from the bracket by turning both the screwdriver and the Smoke/CO Alarm counterclockwise (left) at the same time.

UL217 specifications

The First Alert UL217 is a state-of-the-art smoke and fire alarm designed to provide advanced safety and security for homes and businesses. This model adheres to rigorous standards set by Underwriters Laboratories (UL), ensuring reliability and peak performance for fire detection. One of the standout features of the First Alert UL217 is its use of photoelectric sensing technology. Unlike traditional ionization alarms, which primarily detect fast-flaming fires, photoelectric sensors excel at identifying smoldering fires, which are often more dangerous as they can produce poisonous gases long before flames are visible.

Another significant characteristic of the UL217 is its smart dual-sensor system. This innovative feature combines both photoelectric and ionization technologies, offering comprehensive protection against a wide range of fire types. This dual-action approach ensures that users are alerted to both quick-flame fires and slow-smoldering fires, thus enhancing the overall safety of a living environment.

The UL217 also includes a 10-year sealed battery. This maintenance-free power source eliminates the need for regular battery replacements, allowing homeowners and business operators to enjoy peace of mind knowing their alarms will perform effectively without the hassle of changing batteries. The sealed battery lifespan is designed to last for the entire life of the unit, typically around a decade.

The design of the First Alert UL217 is user-friendly, featuring an intuitive test/silence button that allows users to quickly check the functionality of the alarm. An innovative feature called “Smart Technology” reduces the likelihood of false alarms caused by cooking smoke or steam, ensuring fewer disturbances while maintaining vigilant fire monitoring.

Additionally, the UL217 is equipped with a loud 85-decibel alarm that effectively alerts occupants in the event of a fire. The alarm sound is specifically designed to be heard over typical household noises, ensuring that individuals are promptly informed of potential danger.

In summary, the First Alert UL217 smoke alarm combines cutting-edge technology, durability, and user-centric design to provide effective fire detection and life-saving alerts. Its dual-sensor technology, long-lasting battery, and reliable performance make it an essential component of any comprehensive fire safety plan. Whether in a residential setting or a commercial environment, the UL217 stands as a guardian against the threat of fire.
