Installation and Maintenance
Guide
D
ESCRIPTION
For general guidelines on system planning, design,
installation, commissioning, use and maintenance,
refer to the EN54:14 (2001) standard and local
regulations.
DI1552 Analogue addressable ionisation smoke detector
DT1553 Analogue addressable rate of rise heat detector
DP1551 Analogue addressable optical smoke detector
DP1561 Analogue addressable optical smoke detector
DP1551T Analogue addressable dual optical / heat detector
The 1500 series detectors are designed specifically for use with
the Aritech FP1500 series of analogue addressable fire detection
control panels. On these systems the control panel communicates
with the individual detectors using a unique data transmission
protocol. The detectors continuously monitor the environment
where they are installed and report any changes in smoke or heat
concentration to the control panel. In turn, the control panel
generates the alarm condition if applicable.
The detectors have indicators that flash in a “pre-alarm” condition
and light continuously in a ”full” alarm condition. The system is
reset at the control panel.
An optional remote indicator may be connected from the mounting
base connections and will mimic the detector indicator.
The DP1551 and DI1552 comply with EN54:7 (2000).
I
NSTALLATION
The detectors must not be exposed to dusty or dirty environments.
During building works or repairs, the detectors must be removed.
Smoke detectors should not be installed in environments where
condensation may be present.
The surface of the detector must not be painted.
Positioning
Smoke and temperature detectors are designed to be positioned
on the ceiling and should be well away from ventilation inlets and
air extractors. Once the location is decided, the detector base
should be fitted first either to the pre-wired mounting box or direct
to the ceiling through the S700 mounting supplement.
Connections
The detectors must be connected as shown in figure
X
. The cable
from the last detector on the loop should return to the control panel
to close the loop.
The positive line cable (+) must be connected to terminal 1, and
the negative line (-) to terminal 3. If a remote indicator is used, its
positive line cable (+) must be connected to terminal 2 in the
mounting base and the negative to terminal 3.
To connect the cables in the mounting base, remove a piece of
insulation (about 1 cm in length), pass the cables through the hole
and connect each cable in its proper location. To lock each cable,
unscrew each mounting base connection. Slide the un-insulated tip
of the cable under the metal piece and screw down.
Check cable continuity before connecting.
Addressing
Each detector requires a numeric address between 1 and 125 for
identification purposes. The address may be set using the PG700
portable address programmer or the fire system control panel.
Consult the handset or fire panel manual for more full instructions.
Connecting the detector to the mounting base
Once the mounting base is in position, the detector is connected
by inserting it and turning (figure
Y
). To remove the detector, turn
it in the opposite direction.
Locking catch
All of the detector heads have a locking catch to prevent
unauthorised removal.
To enable locking, the locking catch must be broken (figure
Z
).
After connecting the detector, it will be locked in place.
To remove a locked detector, press through the hole (figure
\
)
using a screwdriver or similar, and turn.
Testing
• Check that all detectors are properly assembled in their
mounting bases.
• Activate the control panel and check for correct operation.
• Check that all of the installed detectors are recognised by the
control panel. If any detector is not recognised, check that no
duplicate addresses have been assigned, check the correct
assembly of the detector and its connection.
• To test smoke detectors, apply smoke or approved aerosol
and verify alarm condition.
• To test heat detectors apply temperature using for example a
hair dryer and verify that the detector goes into alarm.
Consult the fire panel manual for further test procedures.
M
AINTENANCE
In normal environments cleaning should be done at least every
three or four years. It is recommended that random functional tests
be carried out every six months.
DI1552, DT1553, DP1551, DP1551T
No special maintenance required. Only qualified personnel should
carry out cleaning. Do not open the detector head.
DP1561
To be carried out by qualified personnel.
To clean the optical chamber
1. Remove the detector from the mounting base.
2. Remove the detector cover by pressing the catch with a
screwdriver, turning and lifting (Figure
[
).
3. Use a vacuum cleaner or compressed air to remove dust from
the chamber.
4. Replace detector cover and place detector into mounting base.
To replace the optical chamber
To avoid injury wear gloves when changing the
optical chamber.
Follow steps 1 and 2 above.
To remove optical chamber place thumb on the OUT mark of the
steel mesh area, hold the detector and pull firmly (Figure
\
).
To insert the new optical chamber align the hanging mesh (Figure
]
) with its entry area and press down firmly to ensure chamber
clips into place (Figure
^
).
Once the optical chamber has been replaced the detector must be
calibrated with PG700 analogue programmer and calibration unit
before it can be used. See PG700 instruction label for more
details.
