THIS PRODUCT IS AN ANALOGUE-ADDRESSABLE FIXED TEMPERATURE HEAT DETECTOR OPERATING AT 83 DEGREES CELSIUS, AND WHICH UTILISES A HIGHLY LINEAR THERMISTOR CIRCUIT WITH THE THERMISTOR MOUNTED EXTERNALLY. THE HEAT DETECTOR COMPRISES A CIRCULAR LOW-PROFILE ABS-TYPE PLASTIC CASING CONTAINING METAL FASTENINGS AND CONNECTING TERMINALS PLUS A POPULATED PRINTED CIRCUIT BOARD WITH THE THERMISTOR CONNECTED AS A SENSING ELEMENT, TOGETHER WITH AN EXTERNAL 360-DEGREE LIGHT EMITTING DIODE (LED). THE PRIMARY FUNCTION OF THIS PRODUCT IS THE DETECTION OF HEAT. THE HEAT DETECTOR CANNOT BE USED ON ANY STAND-ALONE BASIS, IT IS ONLY USABLE WITH THE NITTAN NFU-7000 RANGE OF FIRE ALARM SYSTEM CONTROL PANELS. THE EXTERIOR LED FITTED SERVES ONLY TO INDICATE WHEN THE DETECTOR IS BEING QUERIED BY ITS CONTROL PANEL OR WHEN THE DETECTOR IS IN ALARM MODE. IT ISN'T INTENDED TO SERVE AS A VISUAL WARNING OF FIRE TO ANY PERSONS NEARBY AND PLAYS NO PART IN THE SENSING FUNCTION OF THIS PRODUCT. NO QUANTITATIVE, CHEMICAL OR SPECTROSCOPIC ANALYSIS IS CARRIED OUT BY THIS PRODUCT. THIS PRODUCT IS IMPORTED SPECIFICALLY FOR NITTAN EUROPE LIMITED, IT MUST NOT BE RE-SOLD AS AN "OFF THE SHELF" ITEM BY GENERAL STORES OR BY ANY NON-SPECIALIST OUTLETS. THIS PRODUCT DOES NOT CONTAIN AN INTEGRAL RECORDING DEVICE NOR ANY AUDIO-VISUAL WARNING EQUIPMENT. THE HEAT DETECTOR IS COMPLIANT WITH UNDERWRITERS' LABORATORIES (UL) STANDARDS. IT MAY BE SOLD SINGLY IN A SMALL CARDBOARD BOX BUT IS MORE COMMONLY DESPATCHED WITHIN LARGER CARDBOARD CARTONS CONTAINING 10 OR 100 UNITS.

A RATE-OF-RISE TEMPERATURE HEAT DETECTOR ALSO HAVING A FIXED TEMPERATURE ALARM AT 57 DEGREES CELSIUS. THE DETECTOR COMPRISES A CIRCULAR LOW-PROFILE ABS-TYPE PLASTIC CASING CONTAINING METAL FASTENINGS AND CONNECTING TERMINALS, A POPULATED PRINTED CIRCUIT BOARD WITH THE THERMISTOR CONNECTED AS A SENSING ELEMENT PLUS AN EXTERNAL 360-DEGREE LIGHT EMITTING DIODE (LED). THE DETECTOR IS ANALOGUE-ADDRESSABLE AND USED IN CONJUNCTION WITH A FIRE ALARM SYSTEM CONTROL PANEL. IT HAS NO IN-BUILT AUDIO OR VISUAL WARNING OR RECORDING DEVICE; THE EXTERIOR LED FITTED SERVES ONLY TO INDICATE WHEN THE DETECTOR IS BEING QUERIED BY ITS CONTROL PANEL OR WHEN THE DETECTOR IS IN ALARM MODE. THE HEAT DETECTOR UTILISES A HIGHLY LINEAR THERMISTOR CIRCUIT WITH THE THERMISTOR MOUNTED EXTERNALLY. THE THERMISTOR CIRCUIT PRODUCES A VOLTAGE PROPORTIONAL TO THE TEMPERATURE WHICH IS SCALED AND TRANSMITTED AS A DIGITALLY ENCODED VALUE TO A CONTROL PANEL. DETECTOR HEAD DIMENSIONS: 104MM DIAMETER X 42 MM H, WEIGHT: 100GM. THE DETECTOR MAY BE SOLD INDIVIDUALLY IN A SMALL CARDBOARD BOX BUT IS MORE COMMONLY DESPATCHED WITHIN LARGER CARDBOARD CARTONS CONTAINING 10 OR 100 UNITS.
