(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.

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.

Figure 7

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.

(c) Replacing the Battery

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
