UN-WSM_RND
UNII WIRELESS SMOKE DETECTOR ROUND
The Wireless smoke detector UN-WSM_RND trans-
mits the following events:
SUPERVISION - A periodical transmission every 7
min. indicates detector’s connection.
ALARM - Alarm transmission triggered by the device
indicating Smoke detection. Horn activated and Red
LED blinking.
LOW BAT – Whenever the battery reaches a its low
level (2.9V), a Battery Low signal will be sent to the
UNii alarm system. Horn will beep and Red LED will
blink every minute. When Battery level drops below
Cut Off level (2.5V) the device will stop functioning
and the Red LED will blink for 10 seconds and then
turned Off.
TAMPER – When the device is removed from the
ceiling, a tamper signal will be sent to the UNii alarm
system. Replacing the detector cancels the tamper
alarm.

WRONG INSTALLATION
LOCATIONS
False alarms occur when smoke detectors are installed
where they will not work properly. To avoid false alarms,
do not install smoke detectors in the following situations:
• Combustion particles are by-products of something
burning. Do not install smoke detectors in or near areas
where combustion particles are present, such as kitchens
with poor ventilation, garages where there may be vehicle
exhaust, near furnaces, hot water heaters and space
heaters.
• Do not install smoke detectors less than 6 meters away
from places where combustion particles are normally
present. If a 6 meters distance is not possible try to install
the detector as far away from the combustion particles as
possible, preferably on the wall. To prevent false alarms,
provide good ventilation in such places.
• The path of fresh air intake. The ow of fresh air in
and out can drive smoke away from the smoke detector
reducing its efciency.
• In damp or very humid areas or near bathrooms with
showers. Moisture in humid air can enter the sensing
chamber, then turns into droplets upon cooling, which can
cause nuisance alarms. Install smoke detectors at least 3
meters away from bathrooms.
• In very cold or very hot areas, including unheated buil-
dings or outdoor rooms. If the temperature goes above
or below the operating range of smoke detector, it will not
work properly.
• In very dusty or dirty areas, dirt and dust can build up
on the detector’s sensing chamber, to make it overly
sensitive. Additionally, dust or dirt can block openings to
the sensing chamber and keep the
detector from sensing smoke.
• Near fresh air vents or very drafty areas like air conditio-
ners, heaters or fans. Fresh air vents and drafts can drive
smoke away from smoke detectors.
• In “Dead Air” spaces like at the top of a peaked roof, or
in the corners between ceilings and walls. Dead air may
prevent smoke from reaching a detector.
• In insect-infested areas. If insects enter a detector’s
sensing chamber, they may cause a nuisance alarm.
Where bugs are a problem, get rid of them before instal-
ling the detector.
• Near uorescent lights, electrical “noise” from uores-
cent lights may cause nuisance alarms. Install smoke
detectors at least 1.5 meter from such lights.
The UNii keypad has a “RF Signal Strength
Indication” in order to help the installer to dene the
best location for the detector from RF perspective.
The indication values are “excellent”, “strong”, “poor”
or “unknown”. If this indication value is “poor” or
“unknown”, it is a sign for a weak or no RF link and it
is recommended to nd a better installation for the
UN-WSM_RND.
INSTALLATION
LOCATIONS
Here are few useful tips for complete coverage in
residential units or small buildings:
• Install a smoke detector on every oor of mul-
ti-oor home, apartment or small building.
• Install a smoke detector in the hall downstairs
near de stairs.
• Install smoke detectors at both ends of
bedroom hallway if hallway is more than 12m
long.
• Install a smoke detector inside every room
where one sleeps with the door partly or com-
pletely closed, since smoke could be blocked
by the closed door and a hallway alarm may
not wake up the sleeper if the door is closed.
• Install basement detectors at the bottom of the
basement stairwell.
• Install second-oor detectors at the top of the
rst-to- second oor stairwell.
• Be sure no door or other obstruction blocks the
path of smoke to the detector.
• Install smoke detectors as close to the center
of the ceiling as possible. If this is not practical,
put the detector on the ceiling, at least 10 cm
away from any wall or corner.
1. Hold the mounting bracket against the ceiling and
mark the center of each slot.
Drill 2 holes and install the bracket with the screws
(see Figure 3-A).
2. Verify the Smoke detector is paired to the control
panel by pressing the TEST button (see below
Figure) and verify receiving suitable message on
the Application / Base.
3. Push the Smoke detector toward the bracket
and turn it clockwise to adjust the detector to the
bracket (see Figure 3-B).

APPROVALS
The re systems help half of residents escape. Help
to old people, men, women and children shall be given
since they are always the victims.
Smoke alarms detectors are not foolproof, they can’t
prevent or extinguish res, and they are not a substi-
tute for property or life insurance. You need buy some
re ghting facilities.
Sometimes the smoke is blocked by objects and can’t
reach the detector, and if the wind blows the smoke
away from the detector, the unit won’t work either.
LIMITATIONS
MUTING AN ALARM
The sound alert of the UN-WSM_RND could be muted
for ve minutes. After ve minutes, if the
UN-WSM_RND continues to detect smoke, the alarm
resumes. To mute the alarm, press the TEST/MUTE
button.

WARNING
1. Never use an open ame of any kind to test your
detector. You may set re to damage the detector as
well as your home. The built-in test button
accurately tests all detector functions. This is the
only correct way to test the unit.
2. To stop a nuisance alarm, open a window or fan
the air around the detector to get rid of the smoke.
The alarm will turn itself off when the smoke is gone.
If nuisance alarms persist, attempt to clean the
detector as described in this manual.
3. Do not stand close to the detector when the alarm
is sounding. The alarm is loud in order to wake you
up in an emergency. Too much exposure to the horn
at close range may be harmful to your hearing.
4. Never try to avoid false alarms by disabling the
detector.
WARNING WARNING
5. Dust can damage the smoke detector’s sensitivity.
The detector needs to be cleaned at least once a
year as described in this manual.
6. If the alarm horn produces a loud continuous
sound when you are not testing the unit, this means
the detector has sensed smoke or combustion
particles in the air. Verify that the alarm is a result
of a possible serious situation, which requires your
immediate attention.
7. The alarm could be caused by a nuisance situa-
tion. Cooking smoke or a dusty furnace, sometimes
called “friendly res” can cause the alarm to sound.
If this happens, open a window or fan the air away to
remove the smoke or dust. The alarm will turn off as
soon as the air is completely clear.
8. This smoke detector is designed for use in a
single residential unit or small buildings only, which
means that it should be used inside a single-family
home, apartment or small buildings. Smoke detec-
tors, placed in common areas outside the individual
living unit, such as on porches or in hallways, may
not provide early warning to residents.
9. This smoke detector, if used as a stand-alone unit,
will not alert people who are hard of hearing.
10. Changes or modi cations to this equipment
not expressly approved by the party responsible for
compliance (Crow Electronic Engineering Ltd.) could
void the user’s authority to operate the equipment.
11. Batteries of this device are not replaceable. Re-
commanded date for device replacement ≥2 years
from rst operation date.
DETECTOR TESTING
After the learning process and installing the
smoke detector, we recommend performing and
transmission tests.
Alarm Test
Press shortly the “Test” button (see g. 2) - the smoke
detector shall activate 3 beeps and Green LED,
indicating that the device is in the normal mode.
If the test fails, stop using the detector immediately.
WARNING – DON’T TEST IT WITH FIRE !!!
Tamper Transmission Test
Removing the smoke detector from its bracket will
cause tamper transmissions.
Verify the UNii keypad (info) indicates “Tamper”. Verify
receiving the indication in the UNii manager software,
by entering to the diagnostics menu.
Communication signal test
Check the RF Communication quality. Special
indication at the UNii keypad that displays
continuously the received RF signal quality.
Never use water, cleaners or solvents to clean your
Smoke detector since they may damage the unit. Use
a soft brush only. Remove the device from its bracket
(by turn it counter clock wise) and carefully remove
any dust from the Smoke’s openings around the
device (see below gure) at least once a year.
