UBS1RF Optical Smoke Alarm
OverView
This optical smoke alarm is a re
detection and alarm device which gives
o󰀨 an audible and visual warning when
it detects the presence of smoke within
a specially designed detection
chamber. Optical smoke sensors
are less prone to false alarms than
ionisation sensors which have
previously been more commonplace,
whilst also being slightly more sensitive
to slower, smouldering res typically seen
around electrical equipment and the fabrics
used for furniture. They are ideal for living rooms,
bedrooms, hallways and near kitchens (but not in kitchens).
During standby, the LED will ash every 50 seconds to indicate normal operation.
When in alarm mode the LED ashes approximately once per second and the
alarm enters into one of the alarm patterns described in the Alarm Signals section.

Suitability
UltraFire’s range of battery-powered re detection and alarm devices are
designed to meet BS 5839-6 Grade F requirements. Even if interlinked as a
network with multiple sensor types, these alarms are only intended for use in
single household premises which are permitted to use battery-powered alarms.
Local Building Regulations, legislation, or other requirements may specify
mains-powered alarms, in which case this product is not suitable.
Multi-household domestic premises and commercial premises usually require
more advanced re detection and alarm systems.
Additional Features
Radio-Interlink
UltraFire radio-interlinked alarms are designed to be wirelessly interlinked as a
network with up to 50 products. These alarms need to be “learned in” or
interlinked in order to communicate with each other. If one alarm activates, all
other interlinked alarms will also sound. They are not designed to communicate
with wireless alarms from other ranges or manufacturers.

Additional Features
Alarm Silence Mode
WARNING: Before silencing an active alarm you must ensure the environment is
safe. Do not silence the alarm in the event of an actual re, as this may prevent
other occupants from evacuating.
When in alarm mode, pushing the test button will silence the unit for
approximately 10 minutes. The red LED will ash as per the Status Indicators
section to indicate that the alarm has been silenced.
The alarm will automatically reset after approximately 10 minutes. If after this
period there are still signs of a potential re then the alarm will sound again. The
alarm silence mode can be repeated.
Do Not Disturb Mode
When the alarm is indicating any kind of fault it will chirp as per the Status
Indicators section. Pressing the silence button at this time will silence the warning
for approximately 8 to 10 hours, ideal for postponing corrective action overnight.
The alarm will still continue to monitor for signs of a potential re during this time,
providing the fault does not prevent normal operation, so it may go into alarm
mode. The alarm’s Do Not Disturb Mode only prevents the fault warning chirp.

• When the battery fails or a low battery is detected, the alarm will chirp once
every 50 seconds in conjunction with the red LED ashing.

Installation
Location
Smoke alarms are recommended for all rooms which are not regularly exposed to
steam, fumes, dust or other contaminants.
Do Not Install in the Following Places:
• On walls, shelves, or cupboards
• Where the alarm is likely to be exposed to liquids
• At the very apex of pitched ceilings
• In the corner of the ceiling
• Within 30cm of a wall, light tting, or other obstruction
• In bathrooms and other rooms that will be exposed to steam
• Near appliances or areas where combustion occurs regularly
• In areas regularly exposed to excess dirt, dust, gases, vapours, or humidity
• Where the ambient temperature regularly exceeds 0°C to 40°C

Placement
UltraFire Wireless Smoke Alarms must be installed on the ceiling, at least 30cm
from the nearest wall, light tting, or other obstruction. The alarms cannot provide
adequate warning of a re if installed on or too close to a wall.
At least one smoke alarm should be installed in each hallway or corridor and on
each main landing of every staircase. In hallways or corridors exceeding 7.5m in
length, no point in the hallway or corridor should exceed 7.5m from the nearest
smoke alarm. For best protection install optical smoke alarms also in living rooms,
dining rooms and bedrooms. This gives the earliest possible warning should a re
start in these rooms.
These alarms should be installed no more than 600mm vertically below the apex
of a pitched ceiling. Where the depth from apex to eaves is 600mm or less the
ceiling should be treated as at.
Try to ensure that the alarm is within reach without taking any undue risks, so that
you can perform routine maintenance and replace the batteries.
Above all else you must ensure that you follow local building regulations,
legislation, and o󰀩cial standards.

Installation Procedure
WARNING: The label on the alarm must not be removed as it shows important
information about the product.
2. Hold the baseplate against the ceiling at the desired installation position.
3. Mark the installation holes with a pencil.
5. Strike the two included plastic rawl plugs into the holes with a hammer.
7. Fit the batteries into the alarm.
8. Follow the instructions in the Radio-Interlink section.
10. After mounting, test the alarm as described in the Maintenance section.
1. Check the desired installation position for wires, pipes, or other obstructions
that would be dangerous to drill into.
6. Align the baseplate to the plastic rawl plugs and x in place using the
provided screws.
4. Drill the two installation holes as previously marked using a 5mm diameter
drill bit.
9. Line the alarm up to the baseplate and turn the alarm head clockwise, until
securely attached.

Radio-Interlink
UltraFire radio-interlinked alarms are designed to be wirelessly interlinked as a
network with up to 50 products. These alarms need to be “learned in” or
interlinked in order to communicate with each other. If one alarm activates, all
other interlinked alarms will also sound. They are not designed to communicate
with wireless alarms from other ranges or manufacturers.
Note: Obstructions such as steel reinforcement in concrete could block or impede
the wireless signal. While the wireless range is over 200m in open spaces, the
e󰀨ective range may be reduced by walls and other obstructions within a building.
It is recommended not to exceed 35m as the maximum distance between the
alarms in a network.
