Universal Security Instruments 3895L, 3304L instruction

The yellow wire is used only for multiple station operation with USI ELECTRIC or UNIVERSAL Model alarms only. Connecting this yellow wire to any other circuits may result in damage and smoke alarm malfunction. When alarms are interconnected, all smoke alarms must be powered from a single AC branch circuit. If local codes do not permit, be sure the neutral wire is common to both phases. The maximum wire run distance between the first and last alarm/device in an interconnected system is 1,000 feet. NOTE: Use standard household wire (18 gauge or larger, rated at least 300V, as required by local codes) available at all electrical supply/hardware stores.

The wiring to be used shall be in accordance with the provisions of Articles 210 and 300.3(B) of the National Electrical Code, ANSI/NFPA70. In addition, the resistance of the interconnecting wiring shall be a maximum of 10 Ohms.

2.Attach the mounting bracket to the electrical junction box.

3.To activate 9 volt battery and alarm, hold the QUICK DRAW(R) battery drawer closed, pull and remove the PULL-TAB. Confirm that the entire PULL-TAB has been completely removed. Discard PULL-TAB.

4.Plug the AC QUICK CONNECTOR into the alarm base. Push and twist the alarm clockwise onto the mounting bracket.

5.See "OPTIONAL TAMPER RESISTANT FEATURES" and "TO ACTIVATE THE LOCKING FEATURES" instructions on Page 4.

6.Turn on AC power and check the LED's for proper operation. The green LED should be on to indicateAC power. The red LED blinks on approx. every 40-45 seconds to indicate proper operation.

OPERATION, TESTING & MAINTENANCE

OPERATION: The smoke alarm is operating once the AC power is connected and turned on (the battery must also be installed). When products of combustion are sensed, the alarm sounds a loud alarm which continues until the air is cleared.

This alarm incorporates the NFPA recognized horn signal for evacuation. During alarm mode, the horn produces three beeps followed by a two second pause and then continually repeats.

READY/ACTIVE CONDITION: The red LED blinks on once approx. every 40-45 seconds to indicate the alarm is properly functioning.

LOCAL ORIGINATING ALARM CONDITION: The red LED blinks on once approx. every 2 seconds and the alarm emits a loud, pulsating alarm sound.

NON-ORIGINATING ALARM CONDITION: The red LED is off and the alarm emits a loud, pulsating alarm.

GREEN LED: The green LED is on whenever AC power is turned on.

NUISANCE ALARMS: The smoke alarm is designed to minimize nuisance alarms. Smoking will not normally set off the alarm unless smoke is blown directly into the smoke alarm. Combustion particles from cooking may set off the alarm if the smoke alarm is located close to the kitchen cooking surface. Large quantities of combustion particles are generated from spills or broiling.

If the smoke 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 above may have caused the alarm. Use the Silence Feature if it is a nuisance alarm, or reset the alarm by pressing and holding the test button for ten seconds. Refer to RESET on Page 7.

TESTING: Test by pushing the Test button on the smoke alarm cover until the alarm sounds, then release. The alarm sounds if all electronic circuitry, horn and battery are working. If no alarm sounds, the alarm may have a power supply failure. Test the smoke alarm weekly to assure proper operation.

ALARM ORIGINATION: The QUICK FIND® Alarm Origination Feature allows the user to identify the initiating alarm smoke alarms in an interconnected alarm system. If an interconnected alarm system is initiated by one of the alarms, when the alarm system exits alarm condition, the user can identify the initiating alarm by:

a.Pressing and releasing the test button on any alarm in the system.

3304L, 3304, 3895, 3895L specifications

Universal Security Instruments (USI) has made a prominent mark in the home security and safety industry with its innovative smoke and carbon monoxide (CO) detectors. Among their standout products are the USI 3895L, 3895, 3304L, and 3304 models, each designed with user-friendly features, advanced technologies, and exceptional reliability.

The USI 3895L is a hardwired smoke and CO detector that features a built-in battery backup, ensuring unwavering protection even during power outages. This model includes a voice alarm system that announces the specific type of danger, whether it be smoke or carbon monoxide, allowing users to respond appropriately. Its continuous self-checking functionality enhances reliability by routinely testing the unit's circuits, battery, and sensors.

The USI 3895, while similar in many ways to the 3895L, emphasizes simplicity and efficiency. This battery-operated model provides a compact design without sacrificing performance. It features a sleek appearance, making it an aesthetic addition to any home, while still offering robust smoke and CO detection capabilities. The 3895 also includes a loud alarm and test/silence button for quick and easy functioning.

Moving on to the USI 3304L, this model is an all-in-one smoke and CO alarm that caters to families and businesses alike. Like the 3895L, it comes with a hardwired setup and a battery backup. The 3304L is particularly praised for its photoelectric smoke sensing technology which minimizes false alarms caused by cooking smoke and steam. This technology increases response times for smoldering fires, giving users valuable time to react.

Lastly, the USI 3304 is a more accessible variant within the same series, designed as a battery-operated smoke and CO detector. Retaining many advanced features of the 3304L, this model is compact and versatile, suitable for various spaces within a home or office. It comes equipped with an LED indicator for operational status and an easy-to-read user manual, ensuring ease of use and installation.

In summary, Universal Security Instruments' 3895L, 3895, 3304L, and 3304 models each provide essential life-saving features with cutting-edge technology. From voice alarms and photoelectric sensing technology to reliable battery backup options, USI delivers robust solutions for fire and carbon monoxide safety. Employing these detectors can significantly enhance home safety while providing peace of mind for families and property owners alike.
