Kidde Complete Guide to the 1235 Smoke Alarm: Operation, Testing, and Maintenance

8.Turn on the A.C. power. The green A.C. Power On Indicator should be lit when the alarm is operat- ing from A.C. power.

TAMPER RESIST LOCKING PIN: To make your smoke alarm somewhat tamper resistant, a locking pin has been provided with your alarm. Using this pin will deter children and others from removing the alarm from trim ring. To use the pin, insert it into the hole in the side of the alarm after the alarm has been installed on the trim ring (see Figure 5). NOTE: The tamper resist pin will have to be removed in order to remove the alarm. Use a long nose pliers to pull the pin out of the hole. It is now possible to remove the alarm from the trim ring.

After installation, TEST your alarm by pressing and holding the test button for several seconds. This should sound the alarm.

4. OPERATION AND TESTING

OPERATION: The smoke alarm is operating once A.C. power is applied and testing is complete. When the smoke alarm ionization chamber senses products of combustion, the horn will sound a loud (85db) temporal alarm until the sensing chamber is cleared of smoke particles.

LED INDICATORS: This smoke alarm is equipped with red and green LED indicators. The red LED is located under the test button and has two modes of operation.

Standby Condition The red LED will flash every 30-40 seconds to indicate that the smoke alarm is operating properly.

Alarm Condition When the alarm senses products of combustion and goes into alarm, the red LED will flash rapidly (one flash per second). The rapid flashing LED and temporal alarm will continue until the air is cleared.

WHEN UNITS ARE INTERCONNECTED, only the red LED of the alarm which senses the smoke or is being tested (the originating unit) will flash rapidly. All other units in the interconnect system will sound an alarm but their red LED’s will NOT flash rapidly.

The green LED has two modes of operation.

Standby Condition The green LED will be steady on, indicating the presence of AC power.

Alarm Condition This smoke alarm is equipped with an alarm memory which provides a visual indication when an alarm has been activated. A flashing green LED indicates the memory condition. The memory will remain activated until it is reset by pushing the test button.

In an interconnected installation only the memory of the originating alarm will be activated.

TESTING: Test by pushing the test button on the cover and hold it down for a minimum of 2 seconds. This will sound the alarm if the electronic circuitry and horn are working. If no alarm sounds, check the fuse or circuit breaker supplying power to the alarm circuit. If the alarm still does not sound, the unit may have other failure. DO NOT use an open flame to test your alarm, you could damage the alarm or ignite combustible materials and start a structure fire.

TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION. Erratic or low sound coming from your alarm may indicate a defective alarm, and it should be returned for service (see Section 12).

5. NUISANCE ALARMS

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 which vents to the outside (non-recirculating type) will also help remove these combustible products from the kitchen.

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 Section 2 may have caused the alarm.

6. MAINTENANCE

ALARM REMOVAL

IF TAMPER RESIST PIN HAS BEEN USED, REFER TO TAMPER RESIST LOCKING PIN IN SECTION 3 FOR PIN REMOVAL INSTRUCTIONS.

You can remove the alarm from the trim ring by rotating the alarm in the direction of the “OFF” arrow on the cover (See Section 3. Figure 4).

To disconnect the A.C. power harness, squeeze the locking arms on the sides of the Quick Connector while pulling the connector away from the bottom of the alarm (see Section 3, Figure 3).

CLEANING YOUR ALARM.

YOUR ALARM SHOULD BE CLEANED AT LEAST ONCE A YEAR.

To clean your alarm, remove it from the mounting bracket as outlined in the beginning of this section. You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum cleaner hose and blowing or vacuuming through the openings around the perimeter of the alarm. The outside of the alarm can be wiped with a damp cloth.
