4. Screw the unit to the wall using the mounting holes. 5. Wire all the rest of the alarms similarly ensuring the terminals marked 1 are all connected together and that the terminals marked 2 are all connected together. 6. After installation press each test button (for at least 15 seconds) in turn and ensure each interconnected unit sounds within 10 seconds. The light (either green or red) will only flash rapidly on the unit with the test button pressed. These Carbon Monoxide Alarms should only be interconnected within the confines of a single family living unit. If they are connected between different units there may be excessive nuisance alarms - everybody may not be aware when they are being tested. 2 2 Figure 8 18 B15583/R0/8/6/06 1:54 PM Page 19 6. TESTING & MONITORING YOUR CO ALARM Button Test It is recommended that you test your CO Alarm after installation and then to make sure the unit is working. It will also help you and your family to become familiar with the sound of the alarm. Press and hold the test button until the alarm sounds (it may take up to 5 seconds) and the green or red light flashes. The alarm will stop sounding shortly after the button is released. If there is a problem follow the checklist below. Power On Indicator Regularly check that the green power light flashes every 45 seconds - the unit cannot work without a good battery, properly connected. Low Battery Indicator If the unit beeps and the green light flashes simultaneously every 45 seconds, then the three batteries are depleted. Check the ‘Replace by’ label on the side wall - if it has been exceeded replace the entire unit. If it has not be exceeded and the batteries are accessible (after the battery door is removed - see figure 5a page 15) replace the batteries. Use only the following Alkaline AA size batteries: Duracell MN1500, Panasonic LR6, GP 15A, Ever Ready LR6 or Energizer E91. (See section 5.2 - page 16, if the locking rivet(s) has been inserted). Insert the new batteries with the orientation shown on the base. Button test the alarm to check the batteries are installed correctly and that they are not depleted. Slide back on the cover. 19 B15583/R0/8/6/06 1:54 PM Page 20 (The batteries will usually last 4 years in standby under normal conditions. An undepleted battery can power a unit in alarm for over 100 hours. The life will be reduced if the unit regularly goes into alarm or if it is exposed to excessive temperatures for long periods). Amber Fault Indicator If the unit beeps and the amber every 45 seconds the self-checking circuitry may have detected a fault. Follow the checklist to see if the unit is actually defective. Checklist in the event of problems Check the ‘pull’ tag has been removed to connect the batteries. Check there are three batteries installed with the correct orientation in the battery compartment. (If the batteries are accessible remove one battery for 1 minute to reset the microcontroller in the unit). If the problem persists replace the batteries if they are accessible. If none of the above solve the problem the unit is probably defective and must be replaced. See “Getting the CO Alarm Serviced Page 28)” . Testing with Carbon Monoxide The unit can be tested with CO by using one of the kits that comes with CO either in a glass phial or aerosol can. Follow the instructions on the kit. It is best if possible to inject the CO gas into the gas entry holes, see Figure 5a. When it senses the CO, it flashes the red light (as per Table B) to confirm that is detecting CO gas. 20 B15583/R0/8/6/06 1:54 PM Page 21 How to distinguish The CO Alarm has a distinctive on-off sound of 3 pulses, followed by a pause as compared with a typical Alarm which has a rapid pulsing sound. In addition, when your CO Alarm detects CO the red light Testing both your CO Alarm and Smoke Alarms weekly will help you and your family to clearly distinguish between them in an emergency. 7. MAINTAINENCE Clean the outside case by occasionally wiping with a clean damp cloth. Do not use any cleaning agents, bleaches, detergents or polishes, including those in aerosol cans. Avoid spraying air fresheners, hair spray, paint or other aerosols near the CO Alarm. Do not place air fresheners near the unit. Use the narrow nozzle of a vacuum cleaner to remove fluff and other contamination from the cover slots to ensure CO gas can reach the sensor - see Gas Sensor positioning shown in figure 5a. Caution: Do not paint the CO Alarm. Remove the CO Alarm when decorating. Do not allow water or dust to contaminate the alarm. Warning: Do not open or tamper with the CO Alarm. There are no user serviceable parts inside This can damage the unit. 21 B15583/R0/8/6/06 1:54 PM Page 22 End of Life When the unit has completed of operation the amber light 40 seconds. The entire unit must then be replaced. It must also be replaced when “Replace Unit by” label on the side wall is exceeded. When the battery is depleted the unit will beep every 45 seconds when the green...
