Fire alarm systems

Heat detectors

4375 and 4376

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.
