The Firex i4618AC Series smoke alarm chirps intermittently due to a low battery warning. The alarm emits a chirping sound to indicate that the battery needs to be replaced. Additionally, the low battery warning chirp can be temporarily silenced for approximately 13 hours by pressing the Test/Hush button.

The Firex i4618AC Series unit may be chirping three times randomly after replacing the battery due to an issue with the smoke-sensing chamber. The manual states that the alarm will "chirp" if abnormal operation of the smoke-sensing chamber is detected. Ensure the battery is properly installed, and use only the specified battery types. If the issue persists, cleaning the unit or resetting it by disconnecting power and reinstalling the battery may help. If the problem continues, the unit may need replacement.

If the door of a Firex i4618AC Series smoke alarm will not close, the likely cause is an improperly installed battery. The unit includes a battery lockout feature that prevents the battery door from closing unless a battery is correctly installed. To troubleshoot:
1. Remove the battery and reinsert it, ensuring correct polarity. 2. Make sure the battery is fully seated in its compartment. 3. Try closing the door again.
This feature ensures the unit will not function without a properly installed battery.

Why does my smoke alarm continue to chirp after replacing the battery

The Firex i4618AC Series smoke alarm chirps after replacing the battery because the low/missing battery monitor circuit remains active during battery replacement. This chirping will stop once the new battery is correctly installed. To avoid this chirp, the unit can be removed from the base and disconnected from AC power while replacing the battery, though this is not necessary.

What to do When the Alarm Sounds! Smoke Alarm Procedure NEVER IGNORE THE SOUND OF THE ALARM! Smoke alarms are designed to minimize false alarms. Cigarette smoke will not normally set off the alarm, unless the smoke is blown directly into the alarm. Combustion particles from cook- ing may set off the alarm if it is located too close to the cook- ing area.

WARNING! REMOVAL OF THE SMOKE ALARM BATTERY AND DISCONNECTING or LOSS OF A.C. POWER WILL RENDER THE SMOKE ALARM INOPERATIVE. ELECTRICAL RATING: 120 VAC, 60HZ, 80mA maximum per alarm (maximum 80mA for originating unit with 24 devices interconnected). 1. RECOMMENDED LOCATIONS FOR ALARMS •...
• Install Smoke Alarms on tray-shaped ceilings (coffered ceilings) on the highest portion of the ceiling or on the sloped portion of the ceiling within 12” (305mm) verti- cally down from the highest point (see figure 4). MOBILE HOME INSTALLATION Modern mobile homes have been designed and built to be energy efficient.

• In dusty areas. Dust particles may cause nuisance alarm or failure to alarm. • In very humid areas (greater than 95% R.H.). Moisture or steam can cause nuisance alarms. • In insect-infested areas. • Smoke alarms should not be installed within 3 ft (.9m) of the following: the door to a kitchen, the door to a bathroom containing a tub or shower, forced air supply ducts used for heating or cooling, ceiling or whole house ventilating fans, or other high air flow areas.

BATTERY INSTALLATION See MAINTENANCE (Section 6) for battery installation. CAUTION! THIS UNIT WILL NOT FUNCTION WITHOUT A PROPERLY INSTALLED BATTERY, AND IS EQUIPPED WITH A BATTERY LOCKOUT FEA- TURE WHICH PREVENTS THE BATTERY DOOR FROM CLOSING IF A BAT- TERY IS NOT INSTALLED CORRECTLY. MOUNTING INSTRUCTIONS CAUTION: THIS UNIT IS SEALED.

NOTE: The alarm will mount to the bracket in 4 positions (every 90 degrees). When wall mounting, make sure the battery box is at the bottom of the unit. (see Figure 5). 6. Pull the Battery Pull Tab completely out of the unit. This will automatically connect the battery.
4. OPERATION AND TESTING OPERATION: The smoke alarm is operating once A.C. power is applied, a fresh battery is installed and testing is complete. When the smoke alarm ionization chamber senses products of combustion, the horn will sound a loud (85db) tem- poral alarm until the sensing chamber is cleared of smoke particles.
Alarm Memory: This smoke alarm is equipped with an alarm memory, which provides a visual indication when an alarm has been activated. The red LED will illuminate for about 1.5 seconds every 16-20 seconds to indicate the memory condition. The memory will remain activated until pushing the Test/Hush Button resets it or will time-out between 11 to 13 hours.

dwelling units are capable of protecting about half of the occupants in poten- tially fatal fires. Victims are often intimate with the fire, too old or young, or physically or mentally impaired such that they cannot escape even when warned early enough that escape should be possible. For these people, other strategies such as protection-in-place or assisted escape or rescue are necessary.

• Have a family meeting and discuss your escape plan, showing everyone what to do in case of fire. • Determine a place outside your home where you all can meet if a fire occurs. • Familiarize everyone with the sound of the smoke alarm and train them to leave your home when they hear it.
- Cleaning with flammable liquids, such as gasoline. - Fires where the victim is intimate with a flaming initiated fire; for example, when a person's clothes catch fire while cooking. - Fires where the smoke is prevented from reaching the detector due to a closed door or other obstruction.
separated by a door from the areas protected by the required smoke alarms. For this reason, it is recommended that the householder consider the use of addi- tional smoke alarms for those areas for increased protection. The additional areas include the basement, bedrooms, dining room, furnace room, utility room, and hallways not protected by the required smoke alarms.
