Ei Electronics Ei186 - Manual (Page 2)

Checking Battery Back-up
The Alarm automatically monitors the battery every 40 seconds
to ensure that it is satisfactory. If it is depleted it will give a short
beep every 40 seconds (models EI 181, EI 184 and EI 186
only).
Before replacing the battery, check that the beeps are not due
to one of the following:
(i) Battery snaps not connected properly.
(ii) On the Optical Smoke Alarms only (EI 186/185) if the unit
beeps and the red light does not flash at the same time it
indicates a problem with the smoke chamber – see Cleaning
the Smoke Alarm section below:
If the beeps have continued for over 20 minutes (and the other
causes of beeps have been ruled out – see below) the battery
must be replaced.
(iii) Switch off the panel voltage supply and remove the unit as
shown in fig 1a. CAUTION: Do not attempt to remove the Alarm
without first releasing the tamper clip. Remove depleted battery
and replace with one of the specified 9V alkaline batteries. The
alarm cannot be replaced on the mounting plate unless a
battery is installed. After replacing the battery, slide on to the
mounting plate and then press the test button and ensure horn
sounds loudly before you turn on the panel supply. Note: Only
use the specified Alkaline batteries shown on the base label
(Duracell MN1604, Eveready 522 or Energizer 6LR61). We
recommend that the “use by date” on the battery should still
have at least 2 years to go. Older batteries will give beeps
prematurely.
We recommend that the battery is replaced each year for
optimum performance.
Please note: The ionisation and heat alarms (EI 180, 181,183
and 184) give two short beeps about a second apart at the end
of the hush period (i.e. about 10 minutes after test/hush button
has been pressed). These two beeps should not be confused
with low battery beeps.
Manual Testing
We recommend that the functioning of the battery back-up is
checked after installation and then at least yearly as follows:-
Turn off (or disconnect) the power at the panel (green light on
mounting plate should be off) press the test button and ensure
the horn sounds loudly for 10 seconds. (This checks the battery
back-up models EI 181, EI 184 and EI 186 only).
Note: A good battery can supply the unit for over a year in
standby (or 5 hours in alarm) without panel power.
In standby, with panel power, the battery can operate for up to 4
years before the low battery beeps start – these will normally
last for over 30 days before the battery is fully depleted.
CLEANING YOUR ALARM
Clean your Alarm regularly, particularly in dusty areas. Use the
narrow nozzle attachment of your vacuum cleaner to remove
dust, insects and cobwebs from the sides and cover slots
where the smoke or heat enters. To clean the cover, wipe with a
damp cloth. Dry cover thoroughly with a lint free cloth.
WARNING: Do not paint your 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.
All Alarms are prone to dust and insect ingress which can
cause false alarms or failure to alarm.
The latest design, materials and manufacturing techniques
have been used in the construction of our Alarms to minimize
the effects of contamination. However it is impossible to
completely
eliminate the effect of dust and insect
contamination, and therefore, to prolong the life of the Alarm
you must ensure that it is kept clean so that excess dust does
not build up. Any insects or cobwebs in the vicinity of the Alarm
should be promptly removed.
In certain circumstances even with regular cleaning,
contamination can build up in the smoke sensing chamber
causing the alarm to sound or fail. If this happens the alarm
must be returned to us for servicing or replacement.
Contamination is beyond our control, it is totally unpredictable
and is considered normal wear and tear. For this reason,
contamination is not covered by the guarantee and a charge is
made for servicing such units.
If you experience persistent false alarms, in particular
locations, due to contamination of the smoke chamber you
could consider replacing Optical Smoke Alarms (EI 186/185)
with Ionisation Smoke Alarms (EI 181/180). Ionisation type
alarms are less susceptible to dust than Optical type alarms.
NUISANCE ALARMS
If there is a nuisance alarm simply press the test/hush button
on the Alarm to silence the unit for 10 minutes.
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 smoke or fumes, for
example 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. If for
some reason the alarm continues to sound without smoke or
heat being present (due to insect infestation or contamination
build-up
for example) the units can be silenced by
disconnecting the mains power and removing the unit (see
figure 1). If cleaning the Alarm does not correct the problem it
can be returned to the manufacturer for repair or replacement
(see Getting Your Alarm Serviced below).
Hush Feature
All the Smoke / Heat Alarms have a combined Test/Hush
Button to help you control nuisance false alarms.
1. To cancel a false alarm, press the Test/Hush Button located
on the cover. The Alarm will automatically switch to a reduced
sensitivity condition (very large levels of smoke from a nearby
fire will override the Hush on the smoke alarms). This condition
allows unwanted alarms to be silenced for a period of
approximately 10 minutes.
The unit will flash the red light every 10 seconds (instead
of the normal 40 seconds) to indicate the sensitivity is
reduced. At the end of the hush period the Ionisation
Smoke Alarm (EI 181/180) and the Heat Alarms (EI 184/183)
will give two short beeps. The Optical Smoke Alarm (EI
185/186) does not give these two beeps.
On interconnected Alarms, pressing the Test/Hush Button on
the one sensing smoke (i.e. the one with the red light flashing
every second) will silence all alarms. Pressing the Hush Button
on any other Alarm will not cancel the alarm.
2. The unit will reset to normal sensitivity at the end of the
silenced period. If additional silenced time is required, simply
push the Test/Hush Button again.
IMPORTANT SAFE GUARDS
• 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. Further
information can be obtained from the Home Office
Publication entitled “Smoke Detectors in the Home” (FB2) or
from your local fire prevention officer.
• NOTE: Constant exposure to high or freezing temperatures
or high humidity may reduce the life of the battery.
• To maintain sensitivity to smoke, do not paint or cover smoke
/heat alarms in any manner; do not permit any accumulation
of cobwebs, dust or grease.
• If a unit has been damaged in any way or does not function
properly,do not attempt a repair. Return Alarm (see - Getting
your Alarm Serviced).
• This appliance is only intended for premises having a
residential type environment.
• Smoke / Heat Alarms are not a substitute for insurance. The
supplier or manufacturer is not your insurer.
• The chamber inside the Ionisation Smoke Alarms (EI
181/180) contains a small amount of radioactive material. Do
not tamper with the chamber. You may safely install and
clean the Smoke Alarm following this leaflet’s instructions.
• In the United Kingdom Ionisation Smoke Alarms can be
disposed 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.
• In the Republic of Ireland Ionisation smoke alarms should be
returned for disposal to the nearest address at the end of this
leaflet.
Do not dispose of your Alarm in a fire.
Use the Smoke / Heat Alarm Test Buttons 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.
PLANNING YOUR ESCAPE FOR WHEN THE
ALARM GOES OFF
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
possible, through a wet cloth or hold
your breath. More people die from
smoke inhalation than from flames.
3. Get out as fast as you can. Do not
stop for packing. Have a prearranged
meeting place outside for all family
members. Check everybody is there.
4. Call the Fire Brigade from a neighb
our’s house. Remember to give your
name and address.
5. NEVER re-enter a burning house.
LIMITATIONS OF SMOKE HEAT ALARMS
Smoke/Heat 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 some circumstances. There are a number of
reasons for this:
• The Alarms will not work if the mains power is off and the
back-up battery is depleted. On the EI181/184/186 alarms
the batteries should be replaced annually and when the unit
gives low battery beeps.
• Smoke/Heat Alarms will not detect fire if sufficient smoke/
heat does not reach the alarm. Smoke/Heat may be
prevented from reaching the Alarm if the fire is too far away,
for example, if the fire is on another floor, behind a closed
door, in a chimney, in a wall cavity, or if the prevailing air
draughts carry the smoke/heat away. Installing Smoke/Heat
Alarms on both sides of closed doors and installing more
than one Smoke/Heat Alarm as recommended in this leaflet
very significantly improves the probability of early detection.
• The Alarm may not be heard.
• A Smoke / Heat Alarm may not wake a person who has taken
drugs or alcohol.
• Smoke / Heat Alarms may not detect every type of fire to give
sufficient early warning. They are particularly ineffective with:
fires caused by smoking in bed, escaping gas, violent
explosions, poor storage of flammable rags and/or liquids,
(for example petrol, paint, spirits etc), overloaded electrical
circuits, arson and children playing with matches.
• Fire Authorities (including the Home Office, UK) recommend
that both Optical and Ionisation Smoke Alarms should be
fitted for the fastest response to all types of fires.
• Smoke / Heat Alarms don’t last indefinitely. For example if
there is a build up of contamination, performance will be
impaired.
The manufacturer recommends replacement of the Smoke/
Heat Alarms after 10 years as a precaution.
ACCESSORY
Smoke Alarm Locator EI 159:
The Smoke Alarm locator is recommended for systems with
three or more Smoke / Heat Alarms as it helps quickly identify
the unit in alarm and reduces the impact of nuisance alarms.
Pressing the Smoke Alarm Locator button will silence all
interconnected alarms for 10 minutes, except those sensing
fire. It is easily installed between the interconnect and 0 volt
terminals.
GETTING YOUR ALARM SERVICED
If your Alarm fails to work after you have carefully read all the
instructions, checked the unit has been installed correctly, and
is receiving panel power contact Customer Assistance at the
address given at the end of this leaflet. If it needs to be returned
for repair or replacement put it in a padded box and send it to
“Customer Assistance and Information” at the nearest address

TROUBLESHOOTING
1. FREQUENT NUISANCE ALARMS OCCUR:
(1) Close kitchen / bathroom door when in use.
(2) Ensure that the alarm is sited at least 6m away from sources of
fumes.
(3) Contamination from insects, paint or paint fumes may have
occurred. Clean the alarm as described in this booklet.
(4) If the problem persists, resiting of the unit should be
considered. Alternatively, replace the unit with an Optical unit
(EI186/185), assuming that the problem is with an Ionisation type
alarm (EI181/180).
2. ALARM SOUNDS FOR NO APPARENT REASON:
(1) Identify the alarm source. On interconnected units, the red
light on the cover will flash rapidly only on the unit which is the
source of the alarm.
(2) Check for fumes, steam etc. from the kitchen or bathroom.
Paint and other fumes can cause nuisance alarms.
(3) Press the test/hush button to silence the Smoke/Heat Alarm
for 10 minutes.
(4) If alarm does not stop, remove the unit (see figure 1). (Only
remove alarm with red light flashing, the others are probably
satisfactory).
3. LOW BATTERY BEEPS:
(On EI 181/184/186 only)
If the battery is correctly connected and the unit has beeped for
over 20 minutes the battery is probably depleted. Obtain a new
battery, remove the alarm and replace the depleted battery. (see
figure 1).
OTHER BEEPS:
(1) If the panel is providing power and replacing battery or
cleaning unit has not stopped beeps, a fault may exist. Replace
the unit (see figure 1).
(2) The Ionisation/Heat units (EI 181/180/184/183) give two
beeps 10 minutes after the test/hush button is pressed.
(3) If the Optical units (EI 186/185) beep without the red light
flashing at the same time, the chamber is defective. Clean the
chamber.
4. INTERCONNECTED ALARMS DO NOT ALL SOUND AND
THE RELAY DOES NOT SWITCH:
(1) Hold test button for 10 seconds after first alarm has sounded
to ensure signal is transmitted to all units. Relay should switch.
(2) Check that the green power light on the mounting plate is on.
(3) Check panel and wiring.
