DF8M – Wireless optical smoke detector - Installation instructions

1 GENERAL DESCRIPTION

The DF8M smoke detector is intended for use with wireless alarm systems that support the
ALPHA or V2GY wireless protocols such as Domonial, G2, Dimension, Lynx and Vista control
panels. Refer to control / communicator installation instructions for compatibility and to know
the maximum number of devices that can be interconnected. The transmitter sends alarm, and
battery condition messages to the system's receiver.
During an alarm, pressing the detector's test switch silences the piezoelectric sounder for 5
minutes. Two LEDs and a sounder on the detector provide local visual and audible indication
of the detector's status:

2 MOUNTING LOCATION (SEE PAGE 1)
We recommend installing one smoke detector in every room where fire is most likely to break
out (except for kitchens and bathrooms). We recommend at least one detector on each level,
for houses with multiple floors.
Smoke rises towards the ceiling, then spreads out horizontally, therefore the ideal place to fix
the detector is on the ceiling in the centre of the room. Make sure that it can be heard loudly
enough in the bedrooms to wake someone.
Install detectors at both ends of a bedroom, a corridor or of a large room if the corridor or the
room is more than 9 m long. For the ceiling of a normal or mansard roof, the detector must be
installed no more than 90 cm from the highest level, measured horizontally.

3 LOCATIONS TO AVOID

• Bathrooms, kitchens, shower rooms, garages or other rooms where the smoke detector
may be triggered by steam, condensation, normal smoke or fumes. Keep at least 6 m away
from sources of normal smoke/fumes.
• Very dusty or dirty areas, as dust build-up in the chamber can impair performance. It can
also block the insect screen mesh and prevent smoke from entering the smoke detector
chamber.
• Insect infested areas. Small insects getting into the smoke detector chamber can cause
intermittent alarms.
• Places where the normal temperature can exceed 40°C or be below 4°C (e.g. attics,
furnace rooms, directly above ovens or kettles etc.) as the heat/steam could cause nuisance
alarms.
• Near a decorative object, door, light fitting, window moulding etc., that may prevent
smoke or heat from entering the smoke detector chamber.
• Surfaces that are normally warmer or colder than the rest of the room (e.g.attic hatches).
Temperature differences might stop smoke or heat from reaching the unit.
• Next to or directly above heaters or air conditioning vents, windows, wall vents etc. that
can change the direction of airflow.
• In very high or awkward areas (e.g. over stairwells) where it may be difficult to reach the
alarm (for testing, hushing or battery replacement).
• Close to dimmer controlled lighting. Locate the unit at least 1m from dimmer controlled
lights and wiring as some dimmers can cause interference.
• Close to fluorescent light fittings. Locate the unit at least 1.5 m away from fluorescent light
fittings as electrical "noise" and/or flickering may affect the unit.
4 INSTALLATION PROCEDURE (SEE 4,5,6,7 ON PAGE 1)
Determine the best location for the smoke detector, one that provides a strong wireless trans-
mission path and proper smoke detection. A good transmission path must be established from
the proposed mounting location before permanently installing the detector.
1. Separate the base from the smoke head by turning the smoke head anti-clockwise.
2. When a suitable location has been found, install the mounting base on the ceiling (if local
ordinances permit).
3. Use the installed link to select the ALPHA or V2GY protocol as required. The link is installed in
the ALPHA position by default.
4. Connect the programming tool to the panel and set the panel into association mode in order to
be able to register the detector automatically after power up.
IMPORTANT: complete step 4 before powering the detector.

5 REGISTRATION
Registration is the procedure associating the DF8M to the control panel. This operation
requires a programming tool. The complete procedure is described in the alarm central unit
installation manual or in the programming tool manual.
Registration is done automatically at power-up after the batteries are installed, therefore panel
must be put into association before pulling the battery tab.
If the registration procedure failed after powering up the device, remove the battery from its
compartment, wait 10sec, and reinstall it noting proper orientation.
Piezoelectric Sounder
The detector must always be registered in its final location with a minimum signal level of 3
units on a scale of 10.

8 MAINTENANCE (SEE 3 ON PAGE 1)
The smoke alarm automatically operates at factory calibrated detection levels, so NEVER
open the chamber while power is applied to the smoke detector. This includes cleaning,
maintenance or screen replacement.
The green LED will blink once every 10 seconds in normal operation. If the battery is not
installed correctly, the smoke detector will not operate and the battery may be damaged. If
the detector does not appear to be sending a signal during any of the tests, check for correct
battery installation and that the battery is fully charged.
Before performing maintenance on the detector, notify the proper authorities and the central
station that the system will be temporarily out of service. Disable the zone or system undergo-
ing maintenance to prevent any unwanted alarms.

Power the detector by removing the paper tab from the battery.
Turn the detector in a clockwise direction in the mounting base until it clicks into place.
Test the detector immediately after completing the installation (as described in the testing section).
Remove the detector from its mounting base by rotating the detector counterclockwise. Re-
move the battery, and dispose of properly.
Wait a minimum of 20 seconds before installing a new battery to ensure a proper power-down
sequence.
Install a new approved 3-Volt Lithium battery in the battery compartment. Follow the polarity
diagram inside the compartment.
Reinstall the smoke detector onto the mounting base by rotating the detector clockwise and test
the detector immediately after completing the operation. If the test fails contact you installer or
the product manufacturer.
Remove the battery from the detector and wait a minimum of 20 seconds to ensure proper
power-down sequence.
Remove the detector cover by turning it counter-clockwise.
Vacuum the cover or use canned air to remove any dust or debris.
Remove the top half of the screen/sensing chamber by lifting straight up.
Vacuum or use canned air to remove any dust or particles that are present on all chamber
sections.
Replace the top half of the screen/sensing chamber by aligning the arrow on the screen/
sensing chamber with the arrow on the housing. Press down firmly until the screen/sensing
chamber is fully seated.
Refit the detector cover by placing it over the screen/sensing chamber and turning it clockwise
until it snaps into place.
Reinstall the battery into the battery compartment noting proper orientation.
Reinstall the detector and test. (See the testing section).
Notify the central station when the system is back in service.
