(d) Cleaning your Smoke Alarm
Clean your Smoke Alarm regularly. Use a soft bristle brush or
the brush attachment of your vacuum cleaner to remove dust
from the sides and cover slots where the smoke enters. Keep
cover closed while cleaning. Do not vacuum or brush inside the
Smoke Alarm. To clean the cover, remove it completely and use
only mild soap and water. Dry cover thoroughly before
replacing it. WARNING: Do not paint your Smoke Alarm.
Other than the maintenance and cleaning described in this
leaflet, no other customer servicing of this product is required.
Repairs, when needed, must be performed by the
manufacturer.
Interconnecting your Smoke Alarms
A maximum of 12 Ei105C Smoke Alarms may be wired
together such that when one unit senses smoke all other units
sound a warning. This helps ensure smoke alarms will be
heard. The unit can be also connected to Ei100C Ionization
type Smoke Alarms. Do not connect to any other device as it
may damage the unit or affect performance.
A maximum of 5,000 feet (1,500 metres) of 18 AWG (0.82mm)
wire can be used, (maximum resistance between detectors 50
ohm). The units are interconnected by wiring all the terminals
marked 1 together, and all the terminals marked 2 together (as in
figure 9 before screwing to ceiling). Draughts from wiring openings,
conduit, or mounting boxes/holes, may blow smoke away from the
sensing chamber, making it insensitive. It is essential that all such
openings be closed by silicone sealant or similar.
After wiring together the Interconnect Smoke Alarms, test the
first unit by pressing the button. All the detectors should alarm
and the test button on the first unit will flash about once a
second. Check all the other units similarly.
These Smoke Alarms should be interconnected only 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 that they are being tested
or that it is a nuisance alarm caused by cooking etc.
Important Safeguards
When using household protective devices, basic safety
precautions should always be followed, including those listed
below:
• Please read all instructions.
• Rehearse emergency escape plans so everyone at home
knows what to do in case the alarm sounds.
• For replacement batteries, refer to label inside smoke alarm.
NOTE: Constant exposure to high or freezing temperatures or
high humidity may reduce the life of the batteries.
• Do not disconnect battery to stop alarm sounding. (Fanning
vigorously with a newspaper or similar will remove nuisance
smoke from the Smoke Alarm and stop it sounding.)
