GENERAL DESCRIPTION
This type of detector (figure 1) continuously samples the temperature variation in the protected
area to provide the earliest warning of fire, offering, at the same time, a high level of false alarm
rejection.
These detectors are designed for an open area protection and must only be connected to control
panels that use the Altair analogue-intelligent addressable communication protocol for monitoring
and control, providing high rates of information exchange and fast and secure responses.
Note: Before installing this device please thoroughly read this leaflet and refer to the applicable
European Standards and National Codes of Practice (e.g. BS5839-1:2002 for UK) for guidance on
location, spacing and acceptable use. Also seek guidance from the compatible control panel
instructions to ensure appropriate design criteria and configuration specifications are followed.
INSTALLATION
For the installation to the ceiling, the detector must be mounted only on the compatible adaptor bases listed in the “TECHNICAL
SPECIFICATIONS” table. Refer to the specific base’s literature for further details.
WIRING
After having installed the base to the ceiling, wiring has to be carried out in order to connect the base to the analogue loop and, so, to
the installation.
Analogue loop wires must be correctly connected to the base’s terminals: check the performed wiring by referring to the figure 2
diagram.
Figure 1
REMOTE OUTPUT CAPABILITY
Remote output capability is available as a standard feature, so a
remote indication lamp or a compatible platform sounder (check
power requirements and loop drive limits) may be wired to the
base terminals (Figure 3).
If other equipment is connected to the remote output, its
supply current must be eventually limited by using an ade-
quate resistor. Consult the TECHNICAL SPECIFICATIONS
table and assess the external device current absorption’s
value.
SHORT CIRCUIT ISOLATORS
The detector is equipped with bi-directional short-circuit isolators
to help protect against wiring faults that may otherwise result in
loop failure. In the event of a short circuit isolators either side
should open to maintain most functions.
Normal operation can be restored after the fault has been correct-
ed.
DEVICE PROGRAMMING - ADDRESS SETTING
Detectors can be addressed using a special hand-held program-
ming unit or they can be automatically addressed from the control
panel (if this feature exists for the model used) after they have
been installed.
Addresses may be selected from a range from 1 to 240, although,
of course, each device on the loop must have a unique address
DEVICE PROGRAMMING - THERMAL SENSITIVITY SETTING
A choice of two thermal sensitivity levels is available; these two
levels correspond to a Rate Of Rise (ROR) A1R category (most
sensitive) and to a category BS (least sensitive), according to the EN 54 part 5
European normative.
Sensitivity level can be selected through a hand-held programming unit or, if such
feature is provided, directly through the control panel.
DETECTOR PLACEMENT
1) Position the detector centrally on its adaptor base ensuring it is level.
2) Rotate clockwise applying gentle pressure. The detector will drop into its keyed
location.
3) Continue to rotate clockwise a few degrees until the detector has fully engaged in
the adaptor base.
4) When the detector is firmly engaged, check the alignment of the raised reference
marks on the detector and on the base (figure 5).
IMPORTANT NOTES ON DETECTORS PLACEMENT
Disconnect loop power before installing the detector.
Dust covers help to protect the devices during shipping and when first installed.
They are not intended to provide complete protection against contamination, therefore,
detectors should be removed before construction, major re-decoration or other dust
producing work is started. Dust covers must be removed before the system can be made
operational.

ANTI -TAMPER DETECTOR LOCK
The detector can be locked to its base as a deterrent to intentional removal performed by non authorized personnel.
Using a cutter, remove the anti-tamper plastic detail, as illustrated in figure 6.
To unlock the detector, insert the tip of a screwdriver into the side slot of the base by exerting only a light pressure (figure 7), and
release the detector by turning it anticlockwise.
LED INDICATORS
This detector is equipped with dual LEDs that can illuminate Green, Red or Amber to indicate
status condition:
Green: blinking, indicates the normal operative status of the detector.
Red: indicates an alarmed condition of the detector.
Amber: if implemented in panel software, indicates a fault condition of the detector.
LED indicators are managed directly by the control panel and the green blinking can be disabled by
the installer either from the control panel itself or through the programming unit.
Positioning of these LEDs is illustrated in figure 8.
IDENTIFICATION TAB
The adaptor base is equipped with a plastic tab where identification data can be visibly displayed.
Detach the tab from the base; write or label it with the required information, then insert it into its adaptor base’s slot.
TESTING THE DETECTORS - PRELIMINARY NOTE
Detectors should be tested after installation and during periodic maintenance
visits; it is recommended each device should be tested at least once per year.
After each test reset the system and allow at least one minute for power stabilisa-
tion.
MAGNET TEST
Position the test magnet next to the detector, in correspondence of the raised
mark, then move it 45 degrees anticlockwise (figure 10).
The magnet test simulates heat on the thermistor and verifies the function of all
electronic circuits of the detector and its communication with the control panel.
The detector should trigger an alarm message to the control panel, and, succes-
sively, the detector’s red LED should be activated by the control panel itself.
HEAT TEST
Use a hair dryer of 1000-1500 W or an heat tool from an approved manufacturer. Direct the heat towards the detector from its side.
Hold the heat source at about 15 cm away from the detector in order to prevent damage to its cover during testing.
The detector should trigger an alarm message to the control panel, and, successively, the detector’s red LED should be activated by
the control panel itself.
MAINTENANCE
Before starting any maintenance work, isolate and disable the system in order to avoid accidental and unwanted alarm or fault condi-
tions.
Remove the detector from its mounting base to allow inspection in good light at ground level.
Inspect the thermistor area and use a small, soft bristle brush to dislodge any evident contaminants such as insects, spider webs,
hairs, etc. Use a small vacuum tube or clean, dry and compressed air to suck up or blow away any remaining small particles from the
thermistor area. Wipe the exterior housing of the detector with a clean, damp, lint free cloth to remove any surface film that can later
attract airborne contaminants.
After all detectors have been inspected, repositioned on their mounting bases and power has been re-applied, check correct opera-
tion by testing the device.

WARNINGS AND LIMITATIONS
Our devices use high quality electronic components and plastic materials that are highly re-
sistant to environmental deterioration. However, after 10 years of continuous operation, it is
advisable to replace the devices in order to minimize the risk of reduced performance caused
by external factors. Ensure that this device is only used with compatible control panels. Detec-
tion systems must be checked, serviced and maintained on a regular basis to confirm correct
operation.
Smoke detectors may respond differently to various kinds of smoke particles, thus application
advice should be sought for special risks. Detectors cannot respond correctly if barriers exist
between them and the fire location and may be affected by special environmental conditions.
Refer to and follow national codes of practice and other internationally recognized fire engineer-
ing standards. Appropriate risk assessment should be carried out initially to determine correct
design criteria and updated periodically.

All devices are supplied with the benefit of a limited 5 years warranty relating to faulty materials
or manufacturing defects, effective from the production date indicated on each product.
This warranty is invalidated by mechanical or electrical damage caused in the field by incorrect
handling or usage. Product must be returned via your authorized supplier for repair or replace-
ment together with full information on any problem identified.
