Page 2: Important Information
1. IMPORTANT INFORMATION WARNING: The Alarm should be permanently wired to the mains by a qualified electrician in accordance with IEE wiring regulations (BS7671). Install a Carbon Monoxide (CO) Alarm in every room that contains a fuel burning appliance, particularly rooms where people spend a lot of time e.g. -
Page 3: Carbon Monoxide - The Silent Killer
The CO Alarm is no substitute for keeping chimneys and flues clear and in good condition, and all of your appliances serviced regularly according to the manufacturer’s instructions. Do not fit alarm until all building work is completed to avoid contamination. 2. - Page 4 Table A: Effects of Carbon Monoxide Poisoning Concentration Inhalation Time (approx) and of CO in Air Symptoms Developed The maximum allowable concentration for continuous exposure in any 8 hour period according to OSHA *. Slight headache after 1.5 hours. Slight headache, fatigue, dizziness, nausea after 2-3 hours.
- Page 5 Pre-Alarm: When the alarm detects over 50ppm CO the red light flashes every 2 seconds. This helps locate CO leaks as the unit gives an indication straight away (without this feature the CO level would need to be at 50ppm CO for 90 minutes for the horn to sound).

5. INSTALLATION Warning: The Alarm must be installed by a competent person. The Alarm is designed to be permanently mounted, using its own built-in terminal block to connect it to the mains wiring. The mounting plate can be screwed directly to the ceiling/wall. Alternatively it can be screwed to a standard junction box (BS 4662 single gang accessory box). - Page 10 The Alarm must be continuously powered 24 hours a day so it is important that it is not on a circuit that can be turned off by a switch. INSTALLATION PROCEDURE 1. Select a location complying with the advice in the previous section.

6. 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. -
Page 14: How To Distinguish Between Co Alarm & Smoke Alarm Warnings
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 4) 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. -
Page 15: Limitations Of Co Alarms
Do not paint the CO Alarm. Remove the CO Alarm when decorating. Do not allow water or dust to contaminate the alarm. Do not open or tamper with the CO Alarm. This can damage the unit and may expose the user to shock or fire hazards. -
