Fire alarm systems 

Heat detectors 

4375 and 4376 

 

Conventional heat detector 

 

Fixed temperature (static) alarm level 

Fixed temperature alarm level 

The conventional fixed temperature (static) 
heat detectors will give an alarm within a 
static response temperature range, within a 
specified response time, in accordance with 
EN54-5:2000 + A1:2002. 

The heat sensitive element is a thermistor. 

The detector is plugged in a conventional 
detector base 2324, connected to a 
conventional zone line input.  An LED on 
the base will light up when the detector goes 
into alarm.  The base also has an output for 
an external LED, e.g. 2218. 

4375 and 4376 

The following types are available (type 
number, temperature and class): 

4375

, 60

°

C, class A2 S. 

4376

, 80

°

C, class B S. 

Latching 

The detectors are latching, i.e. they will not 
be automatically reset if the temperature, 
after the alarm, falls below the detector's 
static response temperature.  The LED in the 
base and a connected external LED will be 
lit until the detector is reset via the c.i.e. 

Environment friendly 

The detectors have unleaded soldering

.  

The latest IC technology reduces the number 
of semiconductors and other electronic 
components to a minimum.  The detectors 
fulfils the RoHS Directive. 

Product applications 

The detectors can be used in the systems 
EBL500 / 512 / 128 / 1000 / 2000 provided 
with some zone line inputs for the system 
respectively (e.g. an 8 zones expansion 
board 1580 / 4580 zone line input, an 
addressable multi purpose I/O unit 3361 
zone line input, etc.). 

Heat detectors are normally used in rooms 
where the temperature can be expected to 
rise rapidly in case of a fire or places where 
smoke detectors can not be used. 

The detectors are intended for indoor use 
and in dry premises premises.
