Installation
This alarm should be installed as late as possible within the schedule of
works, particularly in new build properties, e.g. after decorating and
making good works.
• This alarm must not be connected to any other manufacturer’s alarms.
• The CO (1169) alarm is compatible with itself, Smoke (1163) and
Heat (1165) alarms; and is not compatible with previous
generations.
Important
The circuit powering the safety alarms must be unswitched, i.e.
permanently live. The electrical supply for mains powered alarms with
battery back-up, as required by BS 5839-6 Grade D systems, must:
i) Be an independent circuit from the consumer unit where no other
electrical equipment is connected, or
ii) A separately electrically protected, regularly used local lighting circuit
Also, where alarms are interlinked, they must be connected to a single
circuit.
Safety Instructions
• Ensure the power supply is switched off before installation and
during maintenance.
• These alarms should be installed by a competent person, e.g. a
qualified electrician.
• If the alarm is incorrectly installed or tempered with, this may
result in damage to the alarm, a failure in operation or an
electric shock hazard.
•
These alarms must be installed in accordance with the current
edition of the IET Wiring Regulations BS7671 and the Code of
Practice for the design, installation, commissioning and maintenance
of fire detection and fire alarm systems in domestic premises
BS 5839-6.
•
Important: remove the alarm from the circuit for insulation
resistance testing.
If in doubt, contact a qualified electrician.
Installation
1. Remove the dust cover.
2. Release the alarm from the base by using a screw insert into the slots
and flexing outwards, see diagram. 4
Diagram 4
3. Remove the electrical connector from the alarm by squeezing the
locking arms.
4. Select the cable entry on the base and remove the cut out. Cable
entry can either be through the back of the base or via surface
mounted mini-trunking. Leave the gasket in place to prevent dust
ingress into the alarm.
5. Mount the base in the desired location using the wall plugs and
screws, as required, see diagram 5.
Diagram 5
6. Terminate the live, neutral and earth supply cables and interlink cable
if alarms are interlinked, see diagram 6.
Diagram 6
L (Live): Brown conductor
N (Neutral): Blue conductor
E (Earth): Green / Yellow
I (Interlink): Grey (if using 6243Y cable)
7. A maximum of 12 alarms can be interlinked. If more than 12 alarms
are interlinked it may result in permanent damage.
8. For multiple alarm installations use three core and earth cable
between all the alarms to be interlinked and connect the third core of
that cable to terminal marked I. DO NOT use the earth wire for the
interlink wire. This must be treated as live, i.e. insulated and sleeved.
9. Connect the battery by opening the battery cover and inserting it.
Test the alarm by pressing the TEST button, see diagram 7.
10. Refit the electrical connector.
Diagram 7
11. Attached the alarm to the base
12. Replace the dust cap
13. Turning on the electrical power. The green LED should be lit when the
alarm is operating from the power supply.
14. Test the alarm, including the interlink feature if more than one alarm is
installed.
Important: Remove the alarm from the circuit for insulation
resistance testing.
Warning: The installation of this CO alarm should not be used as a
substitute for proper installation, use and maintenance of fuel
burning appliances including appropriate ventilation and
exhaust systems.
