Macurco CM-S1 specifications Operating Instructions

OPERATING INSTRUCTIONS

When the detector is first powered, the status light will alternate between RED and GREEN as the unit performs a 2-1/2 minute warm-up cycle and self-test procedure. The buzzer on the CM-S1 will cycle twice, emitting its characteristic 4-chirp tone. At the end of this 2-1/2 minute cycle, the status light will turn GREEN to indicate normal operation and safe air. The alarm relay is not energized during the 2-1/2 minute warm-up cycle.

The CM-S1 continuously monitors the air. If the CM-S1 measures levels of CO greater than the danger level, the RED light will turn on, the Alarm Relay will switch to actuate the alarm circuits in the control panel, and the buzzer on CM-S1 units will sound. The computer in the CM-S1 is programmed to alarm if the danger levels of carbon monoxide are exceeded, which are time and concentration-related. The alarm points are: 70 ppm of CO after 60 to 240 minutes, 150 ppm of CO after 10 to 50 minutes, and 400 ppm of CO after 4 to 15 minutes, in accordance with the provisions of UL Standard 2034.

WHEN AN ALARM OCCURS (INSTALLER NOTE: It is recommended the following information below be posted near the control/alarm panel or a copy provided to the customer.)

!WARNING: Actuation of your CO alarm indicates the presence of carbon monoxide (CO) which can KILL YOU. If alarm signal sounds:

1Operate the reset/silence button;

2Call your emergency services (____________________) [fire department or 911];

3Immediately move to fresh air - outdoors or by an open door/window. DO A HEAD COUNT TO CHECK THAT ALL PERSONS ARE ACCOUNTED FOR. DO NOT RE-ENTER PREMISES NOR MOVE AWAY FROM THE OPEN DOOR/WINDOW UNTIL THE EMERGENCY SERVICES RESPONDERS HAVE ARRIVED, THE PREMISES HAS BEEN AIRED OUT, AND THE ALARM REMAINS IN ITS NORMAL CONDITION.

4After following steps 1 - 3, if your alarm reactivates within a 24-hour period, repeat steps 1 - 3 and call a qualified technician (____________________) to investigate for sources of CO from fuel burning equipment and appliances, and inspect for proper operation of this equipment. If problems are identified during this inspection, have the equipment serviced immediately. Note: Any combustion equipment not inspected by the technician, consult the manufacturers' instructions or contact the manufacturer directly for more information about CO safety and the equipment. Make sure that motor vehicles are not, and have not been operating in an attached garage or adjacent to the residence.

CAUTION: This detector will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. Accommodation spaces should be well ventilated when household cleaning supplies or similar contaminants are used.

WARNING: This product is intended for use in ordinary indoor locations of family living units and office workspaces. The CM-S1 is not designed to measure compliance with Occupational Safety and Health Administration (OSHA) commercial or industrial standards.

WARNING: Individuals with medical problems may consider using warning devices that provide audible and visual signals for carbon monoxide concentrations below 30 ppm.

The following symptoms are related to CARBON MONOXIDE POISONING and should be discussed with ALL members of the household:

•Mild exposure: Slight headache, nausea, vomiting, fatigue (often described as “Flu-like” symptoms).

•Medium Exposure: Severe throbbing headache, drowsiness, confusion, fast heart rate.

•Extreme Exposure: Unconsciousness, convulsions, cardio respiratory failure, and death.

Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they are not well, they become so disoriented they are unable to save themselves by either exiting the building or calling for assistance. Young children and household pets may be the first affected.

NOTICE: Transient CO situations can occur:

1.) Excessive spillage or reverse venting of fuel burning appliances caused by outdoor ambient conditions, such as:

a.Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/humid air with extended periods between cycles).

b.Negative pressure differential resulting from the use of exhaust fans.

c.Simultaneous operation of several fuel-burning appliances competing for limited internal air.

d.Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters.

e.Obstruction in or unconventional vent pipe designs, which can amplify the above situations.

2.) Extended operation of unvented fuel burning devices (range, oven, fireplace, etc.).

3.) Temperature inversions, which can trap, exhaust gasses near the ground.

4.) Car idling in an open or closed attached garage, or near a home. The CM-S1 will automatically reset once the air clears.
