(e) Nuisance/False Alarms

If, when the alarm goes off, there is no sign of smoke heat or

noise to indicate that there is a fire, you should get your family

into a safe place, before you start investigating.

Check the house carefully in case there is a small fire smoulder

ing somewhere.

Check whether there is some source of smoke or fumes, for ex

ample cooking fumes being drawn past the Smoke Alarm by an

extractor.

If there are frequent nuisance/false alarms it may be necessary

to re- locate the device away from the source of the fumes.

Fanning vigorously with a newspaper or similar will help silence

alarm.

Installing your Smoke Alarm

(a) Attaching to Ceiling or Wall.

(NB: For Interconnecting see page 9)

The Smoke Alarm is battery operated and needs only wiring, if

the Inter-Link facility is being used.

1. Pull cover open at tab. Remove cover from base by separat

ing at rear snap-in hinges by rotating cover backwards.

2. Place the base on ceiling or wall exactly where you want to

mount the unit. With a pencil, mark the location of the screw

holes.

3. Taking care to avoid any electrical wiring in the ceiling or wall,

drill a hole through the centres of the marked locations. Push

the plastic Screw Anchors provided into the drilled holes. Screw

in firmly.

(b) Connecting the battery

The battery is easily removed from the holder by holding back

one of the plastic clips while lifting the battery with the other

hand.

Snap Battery Connectors to Battery. They fit together only one

way.

Gently push Battery into Battery Holder

With a pencil, write the date of battery installation on the inside of

the cover to remind you when to replace the battery.

To close the cover match up snap-in hinges and gently press to

gether until base and cover snap together. Test the installed

Smoke Alarm - see section “Manually Testing your Smoke

Alarm”.

NOTE: You may hear a loud chirp when attaching the Battery

Connectors to the Battery.

Battery Missing indicator

Some models are fitted with a warning flag which pops up when

the battery is removed. This prevents the cover from closing

when there is no battery in the unit. When the battery is being in

stalled or changed, this flag must be held down while gently

pushing the Battery into the Battery Holder. (Figure 7(a)).

Looking after your Smoke Alarm

(a) Automatic Self-Test

The smoke chamber automatically tests itself every 40 seconds.

If the chamber is degraded it will beep without

the LED flashing

at the same time. If this happens clean the unit. If the beeping

persists and the beep does not coincide with an LED flash, re

turn the unit for service (see “Getting your Smoke Alarm Serv

iced”)

(b) Manually Testing your Smoke Alarm

It is recommended that you test your Smoke Alarm at least once

a month to be sure the unit is working. It will also help you and

your family to become familiar with the sound of the Alarm.

When you press the Test Button it simulates the effect of smoke

during a real fire. So, there is no need to test the Alarm with

smoke.

Press and hold the Test Button until the Alarm sounds (it may

take up to 10 seconds), (Figure 8). The alarm will stop sounding

shortly after the Button is released. If the alarm fails to sound,

follow this checklist.

1. Check Battery Connectors to be sure they are firmly snapped

to the Battery.

2. Replace the Battery. (Check the date marked on the Cover

when you last replaced the Battery).

3. Check for any sign of contamination such as cobwebs or dust

and clean the alarm as described on page 9 if necessary.

WARNING: Do not test with flame.

This can set fire to the alarm and damage the house. We do not

recommend testing with smoke as the results can be misleading

unless special apparatus is used.

A fresh Battery should last about one year. When Battery power

is low and replacement is necessary, the Alarm will “beep” and

the LED will flash at the same time about once per minute for at

least 30 days. The battery must then be replaced. Replace the

battery if the alarm does not sound when the Test Button is

pressed. For maximum reliability, replace battery at least once a

year.

Test the alarm for correct operation using the test button when

ever the battery is replaced.

If the Power Indicator light ceases flashing, replace the battery.

Be sure to replace the Battery as soon as possible to ensure

proper operation and to avoid a leaking Battery. Leakage could

cause damage to the Alarm, furniture, and carpeting.

For replacement batteries, refer to the label inside Smoke Alarm

Cover.

WARNING: Use of any other battery may be detrimental to the

operation of the Smoke Alarm.

(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 leaf-

let, no other customer servicing of this product is required. Re-

pairs, when needed, must be performed by the manufacturer.

Interconnecting your Smoke Alarms

A maximum of 12 EI 105C 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 es

sential 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
