Normal Operation

In normal operation, the alarm will blink the green LED off once approximately every 20 seconds. The display will indicate the current CO readings (if higher than 30ppm) or three dashes (Model CD-9690).

SERVICE/TROUBLE CONDITION

Periodically, the alarm's measurement circuit is tested. If an error is detected, the alarm will sound a double "beep" and the yellow LED will flash on twice approximately every 40 seconds. This is an indication of circuit malfunction and that the alarm required immediate servicing.

When AC power is lost, the green LED is off.

IF THE ALARM SOUNDS:
1.	Operate the Test/Reset button to silence the alarm.
2.	Call your emergency services, fire department or 911; (Phone No.	)

3.Immediately move to fresh air - outdoors or by an open door or window. Do a head count to check that all persons are accounted for. Do not re-enter the premises or move away from the open door or window until the emergency services responder has arrived, the premises have been aired out and your CO alarm remains in its normal condition.

4.After following steps 1-3, if your CO alarm reactivates within a 24-hour period, repeat steps 1-3 and call a qualified appliance technician to investigate for sources of CO from fuel-burning equipment and appliances and inspect for proper operation of this equipment.

If the Display Shows	It Means

30 (or higher)	Developing CO problem. The display will only show levels or
	carbon monoxide 30 ppm or higher.

70 (or higher)	The unit is calibrated to sound an alarm before 240 minutes
	have passed when exposed to this level.

150 (or higher)	The unit is calibrated to sound an alarm before 50 minutes
	have passed when exposed to this level. At this level, an
	average healthy adult may feel headache within 90 minutes.

400 (or higher)	The unit is calibrated to sound an alarm before 15 minutes
	have passed when exposed to this level. This level may be
	life threatening to a normal healthy adult within three hours.

A number higher	Over 450 ppm of CO has been detected. Evacuate
than 450	immediately!

CLEANING YOUR ALARM

You can clean the interior of your alarm by using your vacuum cleaner hose and vacuuming through the openings around the perimeter of the alarm.

The outside can be wiped with a damp cloth. Do not use any household cleaning agents, ammonia based cleaners, paints, varnishes or any other chemical on or near your alarm. AFTER CLEANING, REINSTALL YOUR ALARM. TEST YOUR ALARM

CD-9590, CD-9690 specifications

Universal Security Instruments (USI) has established a reputation for developing reliable and advanced home safety products. Two significant models in their lineup are the CD-9690 and CD-9590, which are smoke and carbon monoxide detectors known for their user-friendly design and innovative technology.

The CD-9690 is notable for its combination of smoke and carbon monoxide detection capabilities. It features a photoelectric smoke sensing technology that is highly effective at identifying slow-burning fires, which can release significant smoke before becoming a full-blown blaze. This technology minimizes false alarms caused by cooking smoke or steam, providing peace of mind for homeowners. Moreover, the unit comes equipped with a voice alarm feature that distinctly announces the type of danger detected, whether it's smoke or carbon monoxide, allowing users to respond more effectively in an emergency.

In contrast, the CD-9590 is a robust carbon monoxide detector that utilizes advanced electrochemical sensing technology. This technology ensures high sensitivity and reliability, enabling the device to accurately detect dangerous levels of carbon monoxide in the environment. The CD-9590 is designed to provide a loud 85-decibel alarm along with a voice alert when CO levels rise above recommended thresholds, ensuring that users are promptly informed of potential hazards.

Both models are equipped with a battery backup system, ensuring they remain operational during power outages. The detectors come with a low battery alert, which signifies when it's time to replace the batteries, reducing the risk of the units being non-functional when needed most.

Another key characteristic of the CD-9690 and CD-9590 is their user-friendly installation. The units are designed for easy wall or ceiling mounting and include mounting hardware in the package. Additionally, the sleek design of both models makes them aesthetically pleasing and easy to integrate into any home decor.

Both models also feature test and silence buttons, allowing users to easily test the functionality of the alarms and silence them during non-emergency situations, further enhancing user control.

Overall, the Universal Security Instruments CD-9690 and CD-9590 detectors combine advanced technology, reliability, and ease of use, making them valuable additions to any safety-conscious home. With their ability to promptly detect and announce various dangers, these detectors play a crucial role in ensuring the safety of residents. Investing in such devices is a proactive step towards home safety and peace of mind.
