1 PURPOSE
The TUN-4046 programmable addressable microprocessor based heat detector is designed for
detection of a fire hazard or fire appearance indication in closed premises, where during the
first phase of fire an occurrence of temperature rise may be observed, or where ambient
temperature may exceed a set fire danger level. It enables programming of appropriate actions
in the place of installation that is it is possible to set up the detector’s class and its operation way
according to the PN-EN 54-5 standard. The TUN-4046 detectors are dedicated for interoperation with
the POLON 4000 and POLON 6000 fire detection and alarm systems. They operate in addressable
loop-shaped detection lines of that system. Every detector is equipped with a program controlled
short circuit isolator.

4 DESIGN DESCRIPTIONS
Fig. 1. TUN-4046 detector overall view
The detector mechanical construction is shown in Fig. 1. Its basic element is a detecting module
consisting of a temperature-sensitive resistor (thermistor). The thermistor, protruding above the
detector casing, is located in the central point and protected against mechanical damages by a
basket. The detecting module is fastened to a printed board that contains all electronic elements and
the detector operation monitoring processor. The detector shape and construction enable free
ambient air flow and its direct impact on the detecting circuit. The whole structure is placed in a
white plastic housing containing a basket, detector cover, ring, and screen.
The TUN-4046 detector is installed in the G-40 base where detection line cables are connected to.
5 PRINCIPLE OF OPERATION
The TUN-4046 heat detector reacts to a rise of temperature occurring during initial phase of fire.
The detector operates in two ways:
-as a fixed temperature detector –after exceeding its set-up temperature activation
threshold, pursuant to its given class;

IK-E283-001GB 5
-as a rate-of-rise heat detector - when a rapid rise of temperature exceeds the level
determined for the detector, pursuant to its given class.
A microcontroller monitors the detector operation, collecting data concerning the ambient
temperature around the detecting circuit, carries out measurement analyses, makes decisions, and is
responsible for communication between the detector and the fire detection control panel.
The detector alarm mode is signalled with flashing light of a red diode which is located in the
detector casing. The indicator enables quick location of the activated detector and is helpful during
periodic detector operation inspections. In case the detector is poorly visible or installed in hardly
accessible place, it can be furnished with an additional optical actuation indicator that should be
mounted in an accessible and visible place.
Communication between the POLON 4000 (POLON 6000) system fire alarm control panel and the
TUN-4046 detectors is provided using a two-wire addressable detection line. A unique, fully digital
communication protocol enables passing any information from the control panel to the detector and
inversely.
Apart from sending to the control panel the temperature value estimation and a tendency of its
change, the detector can transmit –on the control panel request –the current analogue value.
The detector operation controlling microprocessor monitors its basic systems proper operation and,
in a case of irregularity, delivers relevant information to the control panel.
The detector is equipped with an internal short circuiting insulator that cuts off an efficient part of
detection line from the neighbouring shorted section what enables the detector further undisturbed
operation. the alarm mode is indicated with pulse red light emitted by the signalling diode. The fault
mode, technical alarm, and short circuit isolator actuation are signalled with yellow flashes of the
illuminating diode.
The detector is furnished with a possibility to choose a way of reaction in the installation place,
pursuant to a given class. It is the TUN-4046 heat detector so called operation mode. A choice of one
of the following classes: A1, A2, B, A2S, BS, A1R, A2R or BR is made from the control panel level. The
detector with the class set as A2S, BR operates only in a fixed-temperature mode. All operation
modes are accordant with the PN-EN 54-5 standard. The detector operation modes (besides alarm
variants in the control panel) provide the user with an opportunity to adapt, in the best way, the
system operation characteristic to the determined environment conditions.
The TUN-4046 programming procedure is described in the POLON 4900 control panel programming
manual.
6 OPERATION AND SERVICING CONDITIONS
During the detectors operation it is necessary to avoid creation of dew or rime on the detector
surface as well as to protect against excessive dust contamination.
In case of any repair works the detector should be taken out (with consideration of p. 3.1) or
protected with a provided-for-this-purpose cover. Such covers can be obtained from an installer or
purchased from the manufacturer. If the detector is taken out, the base should be protected
against painting with a help of painting tape. Detectors which are damaged during renovation or
painting works due to a fault of executing persons (e.g. painted detector casing) are not subject to
warranty repairs.
The TUN-4046 should be subjected to periodic inspection according to the PKN-CEN/TS 54-14:2006
which is carried out in order to confirm the detector proper operation and its appropriate
interoperation with the control panel. The inspection should be conducted at least once in 6 months.

6 IK-E283-001GB
Such an operation test can be carried out using a heat detector tester.
A thermistor fault (short circuit or disconnection) is revealed by the detector and a fault signal is sent
to the control panel. Any damaged detectors should be passed to the manufacturer (Polon-Alfa, 155,
Glinki Street, PL 85-861 Bydgoszcz, Poland) for repair.
Note: The detector dismantling by the user, installer or maintenance technician is forbidden! Only a
skilled installer is authorised to mount the detectors.
7 DETECTOR INSTALLATION
The TUN-4046 heat detectors are installed (height, arrangement) according to the Scientific and
Research Centre for Fire Protection guidelines. They operate in loop-shaped lines, in loop-shaped
lines with straight branches, or in radial detection lines of the POLON 4000 and POLON 6000 system
(see the POLON 4000 and POLON 6000 system manual).
The detectors are installed in the 40 model range bases. A detection line connection method is
presented in the G-40 base installation and maintenance manual. An additional optical alarm signal
of a detector or a group of detectors can be obtained by connecting the WZ-31 alarm actuation
indicator.
Alarm system cables are routed in accordance with low voltage system (below 42V) regulations as in
force.
ATTENTION –The detectors should not be installed in premises of corrosive atmosphere that
contains caustic gases and vapours as well as high dust level. Steam condensation on the detectors
is inadmissible.
8 STORAGE AND TRANSPORTATION
8.1 Storage
The TUN-4046 detectors should be kept in closed rooms free of any caustic gases and vapours at the
temperature between +0 °C and +40 °C, and relative humidity not exceeding 80 % at +35 °C.
In the time of storing, the detectors should not be exposed to either direct sunlight or heat from
heating equipment.
The detectors storage period in transportation packing should not exceed 6 months.
8.2 Transportation
The TUN-4046 detectors can be carried in closed transport means spaces, in packing that meets the
requirements of transportation regulations in force. The temperature during transportation should
not be lower than -40 °C and higher than +70 °C, and relative humidity should not be higher than
95% at + 45 °C or 80% at +70 °C.
