Warning: Do not interconnect to any other Smoke Alarms.
A maximum of 250 metres (820ft) 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 to- gether, and all the terminals marked 2 together, as shown in Fig- ure 10. An opening should be made in the label covering the wiring hole in the base, and the wires routed into the unit as shown. Note that the wiring inside the unit must be kept clear of the test button contacts, but must not impede the air flow. Drafts from wiring openings, conduit, or mounting boxes/holes, may blow smoke away from the sensing chamber, making it insensi- tive. It is essential that all such openings be closed by silicone sealant or similar.
You must press in and hold the test button for at least 4 to 5 sec- onds, as there is a time delay on some units.

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 every 2 seconds. 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 be- tween 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.
(d) Silencer Smoke Alarm EI 100S
This model has a special false alarm silencer feature to help you control nuisance false alarms.
1.To cancel a false alarm, press the Silencer Button located on the lower
10
2.The unit will reset to normal sensitivity at the end of the si- lenced period. If additional silenced time is required, simply push the Silencer Button again.
3.To quickly return to normal
4.After installation, your Smoke Alarm may chirp approximately every 40 seconds. This indicates it is in the Silencer mode. To put it into normal operating mode, push and hold Test Button un- til alarm sounds.
5.If the cause of the alarm is not clear, it should be assumed that it is due to an actual fire and the dwelling should be evacu- ated immediately.
If usage/layout is such that there are an unacceptable level of nuisance alarms, even with the Silencer Smoke Alarm,
The Silencer Smoke Alarm model number EI 100S is also suit- able for use in touring caravans.
Important Safeguards
When using household protective devices, basic safety precau- tions 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 the information 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.)
Do not attempt to recharge or burn batteries, as they may ex- plode. Wrap in paper and discard normally.
When removing battery, handle carefully to avoid possible eye damage or skin irritation if battery has leaked or cor- roded.
To maintain sensitivity to smoke, do not paint or cover smoke alarm in any manner; do not permit any accumulation of cob- webs, dust or grease.
The chamber located in the center of the Smoke Alarm con- tains a small amount of radioactive material. Do not tamper with the chamber. You may safely change the battery and clean the Smoke Alarm following instructions in this leaflet.
In the United Kingdom Ionisation Smoke Alarms can be dis- posed of in normal household refuse, but due to the tiny amount of radioactive material contained in the unit, no more than one alarm per dustbin.
11
In the Republic of Ireland Ionisation smoke alarms should be returned for disposal to the nearest address at the end of this leaflet.
If unit has been damaged in any way or does not function properly,do not attempt a repair. Return Smoke Alarm (see - Getting your Smoke Alarm Serviced page 14.)
This appliance is intended for household use ONLY and not for commercial or industrial use.
This is not a portable product. It must be mounted following the instructions in this Use & Care leaflet.
Smoke Alarms are not a substitute for insurance. The sup- plier or manufacturer is not your insurer.
(b) Limitations of Smoke Alarms.
Smoke Alarms have significantly helped to reduce the number of fire fatalities in countries where they are widely installed.
However independent authorities have stated that they may be ineffective in up to 35% of all fires. There are a number of rea- sons for this:
Smoke Alarms will not work if the batteries are depleted or if they are not connected, or if the wrong type of battery is used. Test regularly and replace batteries at least yearly or when depleted.
Smoke Alarms will not detect fire if sufficient smoke does not reach the alarm. Smoke may be prevented from reaching the Alarm if the fire is too far away, for example, if the fire is on an- other floor, behind a closed door, in a chimney, in a wall cav- ity, or if the prevailing air drafts carry the smoke away. Installing smoke alarms on both sides of closed doors and in- stalling more than one smoke alarm as recommended in this leaflet very significantly improve the probability of early de- tection.
The Smoke Alarm may not be heard.
A smoke alarm may not wake a person who has taken drugs or alcohol.
Smoke Alarms may not detect every type of fire to give suffi- cient early warning. They are particularly ineffective with: fires caused by smoking in bed, escaping gas, violent explo- sions. poor storage of flammable rags and/or liquids, (for ex- ample petrol, paint, spirits etc), overloaded electrical circuits, arson, children playing with matches.
Smoke Alarms don’t last indefinitely. The manufacturer rec- ommends replacement after 10 years as a precaution.
Planning your Escape for when the Alarm goes off
Use the Smoke Alarm Test Button to familiarize your family with the Alarm sound and to practice fire drills regularly with all family members. Draw up a floor plan that will show each member at least 2 escape routes from each room in the house. Children tend to hide when they don’t know what to do. Teach children how to escape, open windows, and use roll up fire ladders and stools without adult help. Make sure they know what to do if the alarm goes off - see next page.

1.Check room doors for heat or smoke. Do not open a hot door. Use an alternate escape route. Close doors behind you as you leave.
2.If smoke is heavy, crawl out, staying close to floor. Take short breaths, if pos- sible, through a wet cloth or hold your breath. More people die from smoke in- halation than from flames.
3.Get out as fast as you can. Do not stop for packing. Have a prearranged meet- ing place outside for all family members. Check everybody is there.
4.Call the Fire Brigade from a neigh- bour’s house. Remember to give your name and address.
5.NEVER
(b) FIRE SAFETY HINTS.
Store petrol and other flammable materials in proper containers.
Discard oily or flammable rags.
Always use a metal fireplace screen and have chimneys cleaned regularly.
Replace worn receptacles, switches, home wiring and cracked or frayed electrical cords and plugs.
Do not overload electrical circuits.
Keep matches away from children.
Never smoke in bed. In rooms where you do smoke, always check under cushions for smoldering cigarettes and ashes.
Service furnaces and heating systems regularly.
Be sure all electrical appliances and tools have a recognized ap- proval label.
This device cannot protect all persons at all times. It may not protect against the three most common causes of fatal fires:
1.Smoking in bed.
2.Leaving children at home alone.
3.Cleaning with flammable liquids, such as petrol.
