1. INTRODUCTION
The combined optical smoke and rate of rise heat detector is designed to
provide early warning of a fire condition, reacting upon a fixed smoke concen-
tration level or at a rate of rise in temperature or upon fixed temperature level
in the protected area.
2. STRUCTURE AND FUNCTIONING
The detector consists of two main parts: a base and a detector head. The latter
comprises a circuit board and a chamber with heat sensitive element. The
contact plates are fixed to the base.
The detector head is fixed on the base by the means of bayonet joints. When
locating the detector head on the base, make sure the bench mark stands about 20 mm before
the respective bench mark on the base; then rotate clockwise to fix. The bench marks should
fully coincide when fixed.
A flat point screw is provided on the detector head to prevent unauthorized removal. A 2 mm
tip screwdriver is required for locking and unlocking.
The combined detector comprises an optical smoke multisensor part and fixed temperature
heat part. The output signal is a result of the activity of either of the two stand alone unit. The
principle function of the optical smoke multisensor part is based upon smoke particles enter-
ing the smoke chamber causing distraction of infrared rays within the chamber. This activates
the photoreceiver and the detector enters a fire condition. The activation threshold of the optical
smoke multisensor part is factory set at a specific smoke concentration level. It is temperature
dependent and lowers at rise of the ambient temperature, which increases its sensitivity to
the fire parameters.
In identical fire conditions the fire detector reacts upon a smoke concentration at least 15%
lower than that of a regular point optical fire detector with the same sensitivity at normal
temperature.
The principle of function of the fixed temperature heat part is based on the ohmic resistance
alteration in the thermistor as a result of the ambient temperature change. At rise of the ambient
temperature above a specified threshold the fixed temperature heat part is activated. Upon
activation the detector illuminates two red LEDs, situated on the detector head (360° visibil-
ity). The LEDs can be reset and extinguished by momentarily removing the power source.
Detector’s type and sensitivity are marked.
On fig.2 is shown DIP switch for the addresses and the address number label. The DIP switch
is protected by a transparent cover. Address assignment is made through the DIP switch,
according Fire Control Panel FS6000 Instruction Manual, Appendix 9. Fire detectors ad-
dressing is made via special communication protocol.
3. PREPARING THE FIRE DETECTOR FOR OPERATION
3.1. Connection diagram
Connection diagram of a fire detector base to two - wire fire alarm line, using shielded wire,
is shown on fig. 3. Shielded wire is strongly recommended for reducing electromagnetic
interferences.
3.2. Ìounting
Separate the base from the detector head by turning the detector head in an anti-clockwise
direction.
Feed the connection cable through the cable entry in the center of the base. Fix the base on the
ceiling using appropriate fixings. Complete the wiring as shown on fig. 3. Fix the address label
on its appropriate place. Pull the protection cover and assign the necessary address through
the DIP switch. After completion replace the cover and press until a “click” sound is heard.
Note: DIP switch should not be set to middle (null) position, because it would cause an
incorrect reception of a fire detector address by the fire control panel.
Replace the detector head on the base by offering the detector head to the base ensuring bench
marks are no more than 20 mm apart. Rotate the detector head in a clockwise direction to
complete location.
Lock the detector head to the base by screwing the flat point screw, using a 2 mm tip screw-
driver, ensure not to over tighten.
3.3. Testing
Test is made when the fire detector is connected to FS6000 Fire control panel and according
the provided test procedures. Place a permanent magnet on the detector heads surface at the
point marked test periphery. The twin LEDs will illuminate. After removing the magnet the
LEDs should remain lit until reset by momentary interruption of the power supply. In addition
a simulation test of real fire conditions should be completed by both heat probe and smoke
probe.
4. WARRANTY
The manufacturer guarantees compliance with EN 54, Part 5 and Part 7. The warrant period
is 36 months from the date of purchase, providing that requirements stated in the service
schedule have been observed.
