Operation

Hush® Control Feature

Model 1275CA only:

Smoke alarms are designed to minimize nuisance alarms. Cigarette smoke will not normally set off the alarm, unless the smoke is blown directly into the alarm. Combustion particles from cooking may set off the alarm if the alarm is located close to the cooking area. Large quantities of combustible particles are generated from spills or when broiling. Using the fan on a range hood that vents to the outside (non-recirculating type) will also help remove these combustible particles from the kitchen. The Hush® button is extremely useful in a kitchen area or other areas prone to nuisance alarms.

The Hush® feature has the capability of temporarily desensitizing the smoke alarm circuit for about 7 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm.

If the alarm does sound, check for fires first. If a fire is discovered, get out and call the fire department. If no fire is present, check to see if one of the reasons listed in Locations to Avoid may have caused the alarm.

The smoke alarm is desensitized by pushing the Hush® button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately and “chirp” every 30-40 seconds for approximately 7 minutes. This indicates that the alarm is in a temporarily desensitized condition. The smoke alarm will automatically reset after approximately 7 minutes. If after this period particles of combustion are still present, the alarm will sound again.

NOTE: Dense smoke will override the Hush® control feature and sound a continuous alarm.

CAUTION: Before using the alarm Hush® feature, identify the source of the smoke and be certain a safe condition exists.

LED Indicators

This alarm is equipped with red and green LED indicators:

Red LED - Flashing eve ry 30-40 seconds: Indicates that the smoke alarm is operating pro p e r l y .

Red LED - Flashing Rapidly: When the smoke alarm senses particles of combustion and goes into alarm (constant pulsating sound), the red LED will flash rapidly (one flash per second). The rapid flashing LED and pulsating alarm will continue until the air is cleared. When interconnected, only the red LED’s of the alarms that are sensing smoke or are being tested will flash rapidly (originating alarms). All other units in the interconnect system will sound an alarm, but their red LED’s will NOT flash rapidly.

G reen LED - Constantly On: Indicates that the unit is receiving 120 V AC power.

1275CA, 1235CA, PE120CA specifications

The Kidde 1275CA, PE120CA, and 1235CA are advanced smoke alarms renowned for their reliable performance and user-friendly features. These devices play a critical role in home safety, ensuring that occupants are promptly alerted in the event of a fire.

The Kidde 1275CA is a photoelectric smoke alarm that utilizes advanced sensing technology to detect slow-smoldering fires, which produce substantial smoke without significant flames. This type of fire can often go undetected by traditional ionization smoke alarms. Featuring a battery backup, the device ensures functionality even during power outages. The Task Light feature provides a small LED light that can illuminate dark spaces, making it ideal for hallways or bedrooms.

The PE120CA model is another photoelectric smoke alarm, known for its low-profile design and unique safety features. This device also includes a battery backup, enhancing its reliability in emergencies. One standout characteristic of the PE120CA is its Smart Hush Technology, which allows users to temporarily silence false alarms caused by cooking or other non-threatening situations. This feature enhances user convenience and reduces annoyance from unwanted alerts. The smoke alarm also features a loud 85-decibel alarm which is effective in waking sleeping occupants.

The Kidde 1235CA model stands out with its dual-sensor technology, integrating both photoelectric and ionization sensors. This dual approach ensures that it can effectively sense a broader range of fire types, from fast-flaming fires to slow, smoldering ones. Like the other models, it is equipped with a battery backup for continuous operation. The 1235CA also features an alarm memory, which allows users to easily identify whether an alarm was triggered by smoke or steam, minimizing unnecessary confusion during emergencies.

All three models emphasize user-friendly installation and maintenance. They feature a simple mounting design that allows for quick setup, and the battery compartment is easily accessible for replacement. The alarms are also designed with visual indicators, such as LED lights, to provide clear communication about their operational status.

In conclusion, the Kidde 1275CA, PE120CA, and 1235CA smoke alarms are designed with advanced technologies to enhance safety and convenience. Their unique features not only provide comprehensive smoke detection but also ensure peace of mind for users, making them essential components of a home safety plan.
