In the case of CO the premises should be by opening doors and windows. The user should call the gas supplier etc. In the case of fire, doors and windows should be closed to slow the spread of fire. The user should call the fire brigade etc. 5. TESTING 1. Regularly check that the green mains power light is on. The unit cannot detect CO if the mains power is off and the rechargeable battery back-up is depleted. (If it is off check circuit breakers, fuses, wiring etc). 2. Test the unit weekly by pressing the Test/Hush button. Hold the Test button (for up to 10 seconds) until the horn sounds for over 5 seconds. This will help to familiarise you and your family with the distinctive on-off sound of the CO Alarm. This test checks that the electronics and horn are working correctly. If units are interconnected, button test each unit in turn and check all interconnected units alarm. (If the red alarm light flashes when the button is pressed, see 2.4 “CO ALARM MEMORY” on page 9). Alternatively, if an Ei1529RC Remote Control is in the system the unit can be tested by pressing the Test switch on the Ei1529RC. This is equivalent to pressing the Test button on the Alarm. For further information see “ACCESSORIES” on page 32. 3. If the Alarm gives a short beep and the amber fault light flashes every 40 seconds it means the self20 B16132-R0-7/11/07 11:52 AM Page 21 checking circuit has detected Press and hold the Test/Hush button. If the amber light without the horn sounding, the sensor On the Ei261DENRC will show SF indicating Sensor Faulty. 4. If the Alarm fails to operate when the Test/Hush button is pressed, switch off the mains supply distribution fuse board and remove unit from mounting plate for 3 minutes. Put unit back on mounting plate. Reconnect the mains and test again. (This procedure resets the microprocessor . 5. If the unit beeps every 40 seconds (without a light flash) is depleted. (On the Ei261DENRC with depleted cells, the display will show CP to remind you to Connect mains Power) . Connect mains power (ensure green light is on) to allow cells to charge. 6. Once a year check the rechargeable battery by switching off the mains supply and pressing the Test /Hush button for 10 seconds. The horn should sound loudly. Reconnect the mains supply. If the CO Alarm fails any of the above tests it must be replaced immediately (see 9 “GETTING YOUR CO ALARM SERVICED” on page 27) . TESTING WITH CARBON MONOXIDE The unit checks for CO every 4 seconds and as soon as it detects CO, it flashes the red light (as per Table B on page 8) to confirm that is detecting CO gas. Alternatively: Pressing the Test/Hush button causes the unit to check for CO - this is the Fast CO Test Mode. This eliminates the long wait normally required (e.g. up to 90 minutes at 55ppm CO and up to 3 minutes at 330ppm CO) . 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 but be sure to press the Test/Hush button to speed up the CO sampling directly after you expose the unit to the CO. It is best if possible to inject the CO gas into the gas entry holes (see Figure 1). When it senses the CO it will give 3 beeps and the red light will flash as per Table B. It then automatically resets to normal mode. (If unit fails to respond, press the Test/Hush button again as gas can take some seconds to enter sensor) . 21 B16132-R0-7/11/07 11:52 AM Page 22 The Fast CO Test Mode normally does not activate the memory function unless of CO remains in the sensor for a few minutes. (This can be checked by pressing the Test/Hush button. If the red light flashes continuously (indicating CO detected), hold the Test/Hush button for 20 seconds until the red light stops flashing resets). 6. HOW TO DISTINGUISH BETWEEN WARNINGS The CO Alarm has a distinctive on-off sound of 3 pulses followed by a pause, as compared with a typical Smoke/Heat Alarm which has a rapid pulsing sound. In addition, when your CO Alarm is sounding, the red alarm light on the cover will be flashing. Testing both your CO Alarms and Smoke/Heat Alarms weekly will help you and your family to clearly distinguish between them in an emergency. If CO Alarms and Smoke/Heat Alarms are interconnected (and are all sounding), press switch on the Ei1529RC Remote Control to leave just the alarm that has triggered the system sounding. 7. MAINTENANCE Clean the outside case by occasionally wiping with a clean damp cloth (disconnect the the distribution/fuse board first). 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 dust and other contamination from the gas entry holes in the cover of the Alarm to ensure CO gas can reach the sensor. Do not paint the CO Alarm. Remove the CO Alarm when decorating. ...
