The CO Alarm is no substitute for keeping chimneys and flues clear and in good condition, and all of yourappliances serviced regularly according to the manufacturer’s instructions. Do not fit alarm until all building work is completed to avoid contamination. 2. CARBON MONOXIDE - THE SILENT KILLER 2....

A low level for a long period (e.g. 150 ppm for 90 minutes) can cause the same symptoms (a slightheadache) as a high level of CO for a short period (e.g. 350 ppm CO for 30 minutes). Table A shows howexposure to different concentrations of CO generally affects people. Many cases of reported Carbon Mo...

2.3 WHAT HAPPENS WHEN YOUR CO ALARM DETECTS CARBON MONOXIDE ? When the Alarm detects potentally dangerous levels of CO, it flashes the red alarm light and then soundsa loud alarm if the CO persists. The digital display (Model Ei261DENRC only) indicates the CO level inparts per million (ppm) CO. Tabl...

15 4. INSTALLATION The Alarm is designed to be permanentlymounted, using its own built-in terminalblock to connect it to the mains wiring. Themounting plate can be screwed directly tothe ceiling/wall. Alternatively it can bescrewed to a standard junction box (BS4662 single gang accessory box). The a...

The Alarm must not be connected when the house wiring insulation is being checked with high Voltages i.e. do not use an insulation tester on the alarm. Do not use the CO Alarm on an intermittent basis, or as a portable detector for the spillage ofcombustion products from fuel burning appliances or c...

We strongly recommend that you check for the following before connecting the alarm : • check for Live and Neutral using a two probe tester.• check for Live using a neon tester.• check that the Interconnect wire is NOT connected to Live, Neutral or Earth. Do not use an Earth wire for the Interconnect...

11. Connect the mains power to the alarm circuit. Check the green light is on. The CO Alarm is now fully operational and will provide protection against a build up of CarbonMonoxide gas 70 seconds after it is connected to the mains supply. 12. The unit may be tamperproofed further by removing the kn...

4.1 INTERCONNECTING With interconnected alarms, when one unit detects CO all units alarm. All horns will sound but only unitsdetecting CO will flash their red lights. A maximum of twelve Ei261ENRC/261DENRC CO Alarms may be interconnected along with anEi128RBU & Ei128COV relay module (see “ACCESS...

A maximum of 250 metres (820 ft) of wire can be used (maximum resistance between detectors 50Ohms). Connect as shown in Figure 7 . Alarms should be interconnected only within the confines of a single family living unit. If they areconnected between different units there may be excessive nuisance ala...

checking circuit has detected a fault. Press and hold the Test/Hush button. If the amber light flasheswithout the horn sounding, the sensor is faulty. On the Ei261DENRC the display will show SF indicating S ensor F aulty. 4. If the Alarm fails to operate when the Test/Hush button is pressed, switch ...

The Fast CO Test Mode normally does not activate the memory function unless a high level of CO remains in the sensor for a few minutes. (This can be checked by pressing the Test/Hush button. If thered light flashes continuously (indicating CO was detected), hold the Test/Hush button for 20 secondsun...

HOW TO DISCONNECT AND REMOVE THE ALARM: (1) Disconnect the mains supply to the CO Alarm circuit at the distribution/fuse board. (2) Remove tamperproofing screw if fitted (see Figure 1 ). (3) Release catch (as shown in Figure 1 ) and slide unit off mounting plate. SENSOR MODULE REPLACEMENT Replace th...

Note: When the second sensor has completed its 5 years of operation the amber light will flash every 40 seconds. The sensor module can only be replaced once. The entire unit must be replaced after 10 years . The date for replacing the entire unit is given on the ‘REPLACE UNIT BY’ label on the alarm....

- CO Alarms are not suitable as early warning Smoke Alarms. Some fires produce Carbon Monoxide, but the response characteristics of these CO Alarms are such that they would not give sufficient warningof fire. Smoke Alarms must be fitted to give early warning of fire. - This CO Alarm does not detect ...

12. TECHNICAL SPECIFICATIONS Operating Voltage : 230±10% VAC, 50Hz Power : 1 Watt (60 mA) Power on Indicator : Green Light Sensor : Electrochemical Sensor CO Sensitivity : Meets BS EN 50291: 2001. Unit operates as per Table B (on page 8). Electrical Safety : Complies with relevant sections of EN 603...

CO Alarm Memory: : A unit will indicate if it has been in alarm previously by flashing the red light for 2 seconds every 40 seconds (2 flashes for 50 ppm CO, 4 flashes for 100ppm CO and 8 flashes, for 300 ppm CO). When the Test/Hush button is pressed, the red light flashes (as per Table B on page 8)...

- Press the Test/Hush button for approximately 20 seconds to reset the unit. If the beeping and the amber light flashing re-occurs replace the sensor module. 3. ALARM BEEPS EVERY 40 SECONDS (without amber light flashing): - Rechargeable cells depleted. Reconnect mains power if green light is off. 4....

Alternatively, if an optional Ei1529RC Remote Control is fitted, pressing the LOCATE switch when allalarms are sounding will silence all alarms apart from the alarm that is sensing CO/Smoke/Heat. This area can then be safely investigated and if determined that it is a false alarm, press the HUSH swi...
