NOTE: This unit contains no batteries and will not operate without power. 8.0 INSTALLING THE COSTAR® 12SIR FOR RESIDENTIAL USE 8.1 RECOMMENDATIONS One of the most important considerations in any CO alarm system is the location of the alarms. Statistics of the National Fire Protection Association (NFPA) show that most of the fatal CO occurrences happen at night while people are sleeping. Early warning of CO is best achieved by the correct installation of CO alarms. Placement of an alarm in a garage may cause an alarm due to CO from automotive exhaust. 8.2 RECOMMENDED MOUNTING LOCATIONS Put a CO alarm inside each bedroom where the occupant closes the door while sleeping. A closed door can block particulate smoke, but CO gas is likely to get through.

Figure 3: Recommended CO alarm mounting location is 5 to 6 feet from floor. 8.5 CEILING LOCATION: Alarm should be mounted as close as possible to the center of a hallway or room. If this is not possible, the edge of the alarm should be at least 4 inches from any wall. 8.6 LOCATIONS TO AVOID Placing units where they will not operate properly causes nuisance alarms. To avoid nuisance alarms, do not place units: – Within 5 feet (1.5m) of any cooking appliance or furnace. – Near an open window or door, because the fresh air entering the opening may delay CO from reaching the alarm. – In damp or very humid areas or next to bathrooms with showers. Install detectors at least 10 feet (3 meters) away from bathrooms. – In very cold or very hot environments or in unheated buildings or outdoor rooms where the temperature can go below or above the operating range of the alarm. Temperature limits for proper operation are 4.4° C to 37.8° C (40° F to 100° F). – Good ventilation is recommended when household cleaning supplies or similar contaminants are stored or frequently used. 8.7 CONDITIONS WHICH CAN RESULT IN TEMPORARY CO SITUATIONS: 8.7.1 Excessive spillage or reverse venting of fuel burning appliances caused by outdoor ambient conditions, such as: i) Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/humid air with extended periods between cycles). ii) Negative pressure differential resulting from the use of exhaust fans. iii) Simultaneous operation of several fuel burning appliances competing for limited internal air. iv) Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters. v) Obstructions in or unconventional vent pipe designs which can amplify the above situations. 8.7.2 Extended operation of unvented fuel burning devices (range, oven, fireplace, etc.) 8.7.3 Temperature inversions, which can trap exhaust gasses near the ground. 8.7.4 Car idling in an open or closed area garage, or near a home. 9.0 INSTALLATION INSTRUCTIONS: CAUTION!! READ CAREFULLY 9.1 Select proper location 9.2 A mounting plate is provided on the back of the alarm. Remove the mounting plate from the back of the alarm by holding the mounting plate and twisting the alarm in the direction indicated by the "OFF" arrow on the alarm cover. (Figure 6) 9.3 To insure aesthetic alignment of the alarm with the hallway or wall, the UP ARROW on the mounting plate must be : QGI P/N 099-0066-01 REV 10/26/01 Page 4 of 7 Instruction Manual: COSTAR® 12SIR, 12V System CO Alarm A.) Parallel with the hallway walls when ceiling mounting B.) Pointed upward when wall mounting 9.4 Attach the mounting plate on the wall. Be sure the UP text and arrow are facing up. Use the screws and anchors provided to secure the mounting plate. 9.5 WIRING INSTALLATION Internal terminal block for 14-22 AWG wires. 8 screw terminals at 0.2" (5 mm) spacing. 9.5.1 Drill hole in wall or ceiling at center of plate, and pull system wires through the hole. 9.5.2 Remove alarm cover by using the special tool provided on the three locking tabs on the alarm base. (see figure 4) Figure 4 9.5.2 Pull wires through hole at center of alarm base and connect to the internal terminal block as shown on the following wiring diagrams. (see figure 5) Figure 5 NOTE: The form 'C' relay contacts may be wired either N.O. or N.C. according to system panel requirements. These alarms are not designed to drive auxiliary devices 9.5.4 The 12SIR alarms do not include power supervision. This may be accomplished by installing a power supervision relay at the end of the alarm power circuit. No internal backup battery. 9.6 Alignment marks are provided on the edge of the trim plate and the alarm. After installing the mounting plate, place the alarm on the mounting plate with the alignment marks lined up. Twist the alarm in the direction indic...
