GENERAL DESCRIPTION
INSTALLATION
REMOTE OUTPUT CAPABILITY
This type of detector (Figure 1) continuously samples the air and the temperature variation in the protected area to provide the earliest
warning of fire and yet offers a high level of false alarm rejection.
The Velox digital communication protocol employed by the monitoring control panel provides high rates of information exchange in
combination with comprehensive features that ensure fast and secure responses.
These detectors are designed for open area protection and must only be connected to control panels that use the Velox proprietary
analogue-intelligent addressable communication protocol for monitoring and control.
The centrally positioned red LED indicator provides 360° visibility and thus does not require any orientation during installation.
This photo and heat detector must be used in combination with VELOX control panels employing the Velox communication protocol. The
location of detectors should follow recognised national or international application codes of practice.
The detector can be mounted on VELOX adaptor base or VELOX deep adaptor base.
Bases supplied with a metal shorting clip installed between the two negative terminals allow more flexibility when connecting detectors
to the loop and permits the continuity of the loop cabling to be tested after installation and prior to the detectors being fitted.
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.
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 control
panel instructions to ensure appropriate design criteria and configuration specifications are followed.

SETTING THE ADDRESS

Addresses may be selected from a range from 1 to 240 each device on the loop must have a unique address.
TAMPER DETECTION
TESTING
ANTI-TAMPER MECHANICAL BLOCK FEATURE
A fault condition is triggered on the VELOX control panel if a detector, on the loop, is removed from its mounting base.
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:
The detector may be locked onto its base by removing
the small plastic element on the base’s detector blocking
hook by using a suitable tool (e.g. a small screwdriver) in-
serted through the access hole on the side of the mount-
ing base (Figure 3).
To remove the detector from the base, if mechanically
blocked, insert a suitable tool (e.g. a small screwdriver)
through the access hole on the side of the mounting base
(Figure 3).
1. Position the detector cen-
trally on its mounting base
(ensure it is level).
2. Rotate clockwise applying
gentle pressure. The detector
will drop into its keyed loca-
tion.
3. Press more firmly to win the
force of the contacts.
4. Continue to rotate clockwise
a few degrees until the detec-
tor has fully engaged in the
mounting base.
5. When the detector is firmly
engaged verify the alignment
between the detector and the
raised reference marks on the
base (Figure 4).
6. After all detectors and other loop devices have been installed, apply
power to the loop in accordance with the control panel’s installation in-
structions.
7. Test the detectors as described in the section headed “TESTING”.
WARNING
Disconnect loop power before installing the detector.
CAUTION
Dust covers help to protect the devices during ship-
ping 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.

Heat test
Use an heat tool from an approved manufacturer. Direct the heat towards the sensor from its side. Hold the heat source at about 15 cm
away from the sensor in order to prevent damage to its cover during testing or as instructed by the manufacturer.
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 smoke entry ports around
the detector and the thermistor area; 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 and 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. 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 operation as described under the “TESTING” paragraph.
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.
WARNINGS AND LIMITATIONS
WARRANTY
Our devices use high quality electronic components and plastic materials that are highly resistant to environ-
mental 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 VELOX control panels. Detection systems must be checked, serviced and maintained on a regular
basis to confirm correct operation.
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 standards.
Appropriate risk assessment should be carried out initially to determine correct design criteria and updated
periodically.
