GENERAL DESCRIPTION
This type of detector (figure 1) continuously samples the air in the protected area to provide the earliest warning of fire and yet offers
a high level of false alarm rejection.
The digital communication protocol employed by the monitoring control panel provides high rates of information exchange in combi-
nation with comprehensive features that ensure fast and secure responses.
This device benefits from a “Double Dust Trap” incorporated into the design of the smoke entry ports, hence limiting potential con-
tamination and extending periods between maintenance without compromising sensitivity of response. These detectors are designed
for open area protection and must only be connected to control panels that use the proprietary analogue-intelligent addressable
communication protocol for monitoring and control.
The centrally positioned three-colour LED indicator (red, green and amber) provides 360° visibility and thus does not require any
orientation during installation.
An in-built magnet test allows easy activation to verify correct functioning of the detectors on site.
INSTALLATION
This photo detector must be used in combination with compatible control panels employing the communication protocol. The loc ation
of detectors should follow recognised national or international application codes of practice.
The detector may be mounted on any of the following bases:
adaptor base / deep adaptor base
Universal adaptor base / deep adaptor base
adaptor base with shorting clip / deep adaptor base with shorting clip
Universal adaptor base with shorting clip / deep adaptor base with shorting clip
Bases supplied with a metal shorting clip installed between the two negative terminals allow more flexibility when connecting detec-
tors to the loop and permits the continuity of the loop cabling to be tested after installation and prior to the detectors being fitted.
Care must be taken to ensure that the shorting clip is either cut or removed prior to system commissioning!
Connections to the base terminals are polarity sensitive thus please check by referring to the wiring diagram in figures 2, 3,
4 and 5!

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.
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) may be wired to the base terminals.
If other equipment is connected to the remote output, its supply current must be eventually limited by using an adequate
resistor. Consult the TECHNICAL SPECIFICATIONS table and assess the external device current absorption’s value.
SHORT CIRCUIT ISOLATOR
All standard series devices are provided with short-circuit monitoring isolators on the intelligent loop’s line and can be activated by
the control panel.

the base’s reference raised marks.
CAUTION
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 con-
struction, major re-decoration or other dust
producing work is started. DUST COVERS
MUST BE REMOVED BEFORE THE SYSTEM
CAN BE MADE OPERATIONAL.
WARNING
Disconnect loop power before installing the
detector.
SETTING THE ADDRESS
Detectors can be addressed using a special hand-held programming unit or they can be auto-addressed by the control panel after
they have been installed (the implementation of the auto-addressing feature depends on the control panel’s manufacturer).
Addresses may be selected from a range from 1 to 240, although, of course, each device on the loop must have a unique address.
5. When the detector is firmly engaged verify the alignment
between the detector and the raised reference marks on the
base (figure 7).
6. After all detectors and other loop devices have been
installed, apply power to the loop in accordance with the
control panel’s installation instructions.
7. Test the detectors as described in the section headed
“TESTING”.
1. Position the detector centrally
on its mounting base (ensure it is
level).
2. Rotate clockwise applying
gentle pressure. The detector will
drop into its keyed location.
3. Press more firmly to win the
force of the contacts.
4. Continue to rotate clockwise a
few degrees until the detector has
fully engaged in the mounting
base.
ANTI-TAMPER MECHANICAL BLOCK FEATURE
The detector may be locked onto its base by remov-
ing the small plastic element on the base’s detector
blocking hook by using a suitable tool (e.g. a small
screwdriver) inserted through the access hole on
the side of the mounting base (figure 6).
To remove the detector from the base, if mechani-
cally blocked, insert a suitable tool (e.g. a small
screwdriver) through the access hole on the side of
the mounting base (figure 6).

TAMPER DETECTION
A fault condition is triggered on the protocol compatible control panel if a detector, on the loop, is removed from its mounting base.
TESTING
Detectors should be tested after installation and during periodic maintenance visits (it is recommended each device should be tested
at least once per year). When the system has been reset, allow, after each test, at least one minute for power stabilisation before the
next test. Detectors can be tested as follows:
Aerosol (simulated smoke) test
For this test only use test aerosols from an approved manufacturer, in accordance with their application instructions, in order to
prevent contamination or possible damage to the detector. We suggest to spray the aerosol into the detector by using a recom-
mended applicator. 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.
If the detector does not respond to the tests correctly it may be necessary to clean it: in this case follow the instructions indicated in
the “MAINTENANCE” paragraph.
If testing fails again after maintenance then replace the detector with a new one and return the faulty one for servicing.

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 smoke entry ports
around the detector 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 smoke
entry screen 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. Use the hand-held programming unit to read the pollution percentage of the chamber; please,
refer to the programming unit instruction manual.
After all detectors have been inspected, repositioned on their mounting bases and power has been re-applied, check correct opera-
tion as described under the “TESTING” paragraph.
SENSITIVITY SETTINGS
A choice of four sensitivity levels are available which can be set via the hand-held programming unit or by panel selection (if pro-
vided). Level 1 is most sensitive, level 4 is least sensitive.
Magnet test
Position the magnet (model TMD-01, optional) next to the detector, between the two raised marks on the base (figure 7). The magnet
test simulates smoke in the optical chamber 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, successively, the detector’s red LED
should be activated by the control panel itself.
WARNINGS AND LIMITATIONS
Our devices use high quality electronic components and plastic materials that are highly resistant 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. Detection systems must be checked, serviced and
maintained on a regular basis to confirm correct operation.
Smoke sensors may respond differently to various kinds of smoke particles, thus application advice
should be sought for special risks. Sensors 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 engineering stan-
dards.
Appropriate risk assessment should be carried out initially to determine correct design criteria and up-
dated periodically.
