Ei Electronics EI 103C - Manual (Page 2)

1. Pull Cover open at Tab (2). Do not remove Cover from base.
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 (6)
3. Taking care to avoid any electrical wiring in the ceiling, drill a
hole through the centers of the marked locations. Push the plas-
tic Screw Anchors provided into the drilled holes. Screw in
firmly.
(b) Connecting the battery.
With a pencil, write the date of Battery installation on the inside
of the Cover to remind you when to replace the battery (4).
Lift Battery from Battery holder, and snap Battery Connectors to
Battery. They fit together only one way (Figure 4).
NOTE: You may hear a loud chirp when attaching the Battery
Connectors to the Battery. Test the installed Heat Alarm - see
section 6(a) below.
Some models will be fitted with a battery missing indicator warn-
ing flag which pops up when the battery is removed. This pre-
vents the cover from closing when there is no battery in the unit.
When the battery is being installed or changed, this flag must be
held down while gently pushing the Battery into the Battery
Holder. (see figure 5).
5. Interconnecting your Heat Alarms and
Smoke Alarms.
A maximum of 12 interconnect EI 103, EI 100C and EI 105C
Heat/Smoke Alarms may be wired together so that when one
unit senses fire all other units sound a warning. This helps en-
sure the alarms will be heard.
Warning: Do not interconnect to any other Heat / Smoke
Alarms
A maximum of 820 feet (250 metres) of wire can be used, (maxi-
mum resistance between detectors 50 ohm). The units are inter-
connected by wiring all the terminals marked 1 together, and all
the terminals marked 2 together, as shown in Figure 6. An open-
ing 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 con-
tacts, and must not impede the air flow. Drafts from wiring open-
ings, 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 Alarms, test the first unit
by pressing the button. All the detectors should alarm within 10
seconds and the red light only on the unit being tested, will flash
about once a second. Check all the other units similarly.
These Alarms should be interconnected only within the confines
of a single family living unit. If they are connected between differ-
ent units there may be excessive nuisance alarms. Everybody
may not be aware that they are being tested or that it is a nui-
sance alarm caused by cooking etc.
6. Looking after your Heat Alarm
(a) Testing your Heat Alarm
It is recommended that you test your Heat Alarm once a week to
be sure the unit is working. Press and hold the Test Button until
the alarm sounds (it may take up to 10 seconds) see figure 7. It
will also help you and your family to become familiar with the
sound of the Alarm.
(b) Testing with Heat
When you press the Test Button it simulates the effect of Heat
during a real fire. So, there is no need to test the Alarm with
Heat.
WARNING: Do not test with flame.
This can be a fire hazard in itself.
If you want to check your Alarm with heat we recommend using
a hair dryer with a power rating of at least 1000 watts. Direct the
hot air as shown in figure 8 on to the heat sensor and the alarm
should sound within 30 seconds.
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. Refer to “Cleaning Your Heat Alarm” 6 (d).
(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” about
once per minute for at least 30 days. The battery must then be
replaced. Replace battery if the alarm does not sound when the
Test Button is pressed. For maximum reliability, replace battery
at least once a year.
If the Power Indicator light ceases flashing every 40 seconds re-
place the battery. Be sure to replace the battery as soon as pos-
sible to ensure proper operation and to avoid a leaking battery.
Leakage could cause damage to the Alarm, furniture, and car-
peting.
For replacement batteries, refer to the label inside the Heat
Alarm Cover.
WARNING: Use of any other battery may be detrimental to the
operation of the Heat Alarm.
(d) Cleaning your Heat Alarm
Heat Alarms are not as susceptible to dust and contamination as
Smoke Alarms but it is prudent to clean them periodically. Use
the narrow nozzle attachment of your vacuum cleaner to re-
move dust, insects and cobwebs from the sides and cover slots
where the heat enters. To clean the cover, wipe with a damp
cloth. Dry cover thoroughly with cloth.
WARNING: Do not paint your Heat Alarm.
Other than the cleaning described above, no other customer
servicing of this product is required. Repairs, when needed,
must be performed by the manufacturer.
7. Nuisance 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
smould-ering somewhere.
Check whether there is some source of heat, fumes or smoke,
for example steam from a kettle triggering a Heat Alarm or cook-
ing fumes being drawn past a Smoke Alarm by an extractor. The
Heat Alarm or Smoke Alarm initiating the alarm can be identified
as it will have a rapidly flashing red light. If there are frequent nui-
sance/false alarms it may be necessary to re-locate the offend-
ing device away from the cause of the alarm.
8. (a) 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 label inside Heat 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 heat from
the Heat Alarm and stop it sounding.)
· Do not attempt to recharge or burn batteries, as they may
explode. 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 heat, do not paint or cover Heat
Alarm in any manner; do not permit any accumulation of
cobwebs, dust or grease.
· If unit has been damaged in any way or does not function
properly,do not attempt a repair. Return Heat Alarm (see -
Getting your Heat Alarm Serviced page 11.)
· This appliance is only intended for premises having a resi-
dential type environment.
· This is not a portable product. It must be mounted following
the instructions in this leaflet.
· Heat Alarms are not a substitute for insurance. The supplier
or manufacturer is not your insurer.
(b) Limitations of Heat Alarms
Heat Alarms combined with Smoke Alarms can significantly
help to reduce the risk of fire fatalities.
However independent authorities have stated that these sys-
tems may be ineffective in some fire situations. There are a
number of reasons for this:
