RATE OF RISE HEAT DETECTOR
WITH ADDRESS MODULE
TERMODIFERENCIJABILNI
JAVLJA^ PO@ARA
6120L
1. INTRODUCTION
The Rate of rise heat detector is designed to provide
early warning of a fire condition reacting upon a
sensitive rate of rise in temperature and/or upon
reaching a fixed temperature threshold.
1. UVOD
Termodiferencijabilni javlja~ po`ara je namenjen za otkrivanje
po`ara u ranoj fazi raguju}i na brzinu porasta temperature ili pri
prelasku maksimalne zadate temperature.
2. STRUKTURA I PRINCIP RADA
2. STRUCTURE AND FUNCTION
The detector consists of two parts: a base and a detectors head. The
latter comprises a circuit board and a chamber with head sensitive
element. The contact plates are fixed to the base.
The detector head is fixed on the base buy 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 principle of function of the detector is based on the ohmic
resistance alteration in the thermistor as a result of the ambient
temperature change. It detects a rise in temperature by sensing a
differential in circuit resistance caused by changes in the state of the
thermistors.
Upon activation the detector illuminates two red LEDs, situated on
the detector head (360
0
visibility). 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 addressing is made via special communication protocol.
3. PREPARING THE DETECTOR FOR OPERATION
3.1 Connection diagram
Connection diagram of a fire detector base to two-wire fire alarm
line, usig shielded wire, is shown on fig.3. Shielded wire is strongly
recommended for reducing electromagnetic interferences.
3.2 Mounting
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 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 screwdriver, 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 a heat probe.
4. WARRANTY
The manufacturer guarantees compliance with EN 54 Standard, Part 5.
The warrant period is 36 months from the date of purchase,
providing that requirements stated in the service schedule have
been observed.
Detektor se sastoji iz dva osnovna dela: ku}i{ta i glave
detektora. Glava detektora se sastoji od {tampane plo~e i
termo elementa. Kontaktni priklju~ci su fiksirani na ku}i{tu.
Detekrorska glava je pri~vr{}ena na ku}i{te bajonetnom vezom.
Pri postavljanju detektorske glave u ku}i{te reperi na ku}i{tu i glavi
treba da su udaljeni oko 20 mm pre upadanja u `leb posle ~ega
okrene}emo glavu detektora u smeru kazaljke na ~asovniku. do
zabravljivanja. Reperi moraju biti poklopljeni. Pljosnati vijak
zabravljiva~ je predvi|en za spre~avanje neovla{}ene demonta`e.
Odvija~ od 2 mm je potreban za zaklju~avanje odn. otklju~avanje.
Princip rada detektora se zasniva na promeni omskog otpora
termistora kao rezultat promene spolja{nje temperature. On detektuje
porast temperature o~itavaju}i razliku u otpornom kolu uslovljenu
promenama stanja termistora.
Posle aktiviranja LED indikatori svetle crveno, i sme{teni su u glavi
detektora (vidljivo u krugu 360
0
). LED indikatori mogu biti resetovani
samo momentalnim kratkim prekidom napajanja detektora.
Na detektoru su ozna~eni tip i osetljivost detektora.
Na slici 2 prikazan je DIP prekida~ za adresiranje i oznaka adrese
javlja~a. DIP prekida~ je za{ti}en providnim poklopcem. Postavljanje
adrese javlja~a vr{i se preko DIP prekida~a, prema Uputstvu adresne
centrale FS6000, Poglavlje 9. Adresiranje javlja~a se omogu}ava
specijalizovanim protokolom.
3. PRIPREMA JAVLJA^A ZA RAD
3.1 Shema veze
Shema veze ku}i{ta javlja~a i dvo`ilnog voda sa {irmom je prikazana
na slici 3. [irm se obavezno preporu~uje zbog otklanjanja
elektromagnetnih interferenci.
3.2 Monta`a
Razdvojiti ku}i{te od glave detektora okre}u}i ga suprotono kretanju
kazaljke na satu.
Provu}i kabli kroz centralni otvor na ku}i{tu. Pri~vrstiti ku}i{te za zid
ili plafon odgovaraju}om vij~anom vezom. Izvr{iti o`i~enje kao {to je
prikazano na slici 3. Postaviti oznaku adrese na odgovaraju}e mesto.
Ukloniti za{titni poklopac i dodeliti adresu pomo}u DIP prekida~a.
Vratiti za{titni poklopac pritiskaju}i ga dok se ne ~uje zvuk “klik”.
Napomena: DIP prekida~ ne setovati u srednji (nulti) polo`aj zato {to
}e usloviti neta~nu detekciju po`ara protivpo`arne centrale.
Vratiti glavu detektora u ku}i{te tako da reperi budu udaljeni oko 20
mm. Okrenimo glavu detektora u smeru kazaljke na satu do
zabravljenja.
Osigurajmo glavu detektora za ku}i{te pomo}u zabravljiva~a, ne
prete`u}i, pomo}u dvomilimetarskog odvija~a.
3.3 Test
Test se sprovodi kada je javlja~ vezan za protivpo`arnu centralu prema
predvi|enoj test proceduri. Staviti permanentni magnet na povr{inu
glave detektora na mestu TEST. Indikatori treba da svetle. Posle
pomeranja magneta indikatori moraju i dalje da svetle sve do
resetovanja indikatora.
Test se mo`i izvr{iti i sondom za topli vazduh.
