Thermal sensor (temperature sensor)
A thermistor in a resistance network is used as a
thermal sensor; an analog-digital converter measures
the temperature-dependent voltage at regular
intervals.
When the maximum temperature of 54°C is exceeded
(thermal maximum), or if the temperature rises by a
defined amount within a specified time (thermal
differential), the temperature sensor triggers the alarm
status.
Chemical sensor (CO gas sensor)
The main function of the gas sensor is to detect
carbon monoxide (CO) generated as a result of a fire,
but it will also detect hydrogen (H) and nitrous
monoxide (NO). The sensor signal value is proportional
to the concentration of gas. The gas sensor delivers
additional information to effectively suppress
deceptive values.
Depending on the service life of the gas sensor, the
OC 310 detector switches off the C sensors after five
years of operation. The detector will continue to
function as an O detector. The detector should then
be exchanged immediately in order to be able to keep
using the higher reliability of detection of the OC
detector.

Installation/configuration notes

• Up to 32 detectors can be connected per primary
line.
• Maximum cable length: 1000 m, for J-
Y(St) Y n x 2 x 0.6/0.8
• Country-specific standards and guidelines must be
observed during the planning phase.
• The detector can be painted (cap and base) and
thereby adapted to the surrounding colour scheme.
Note the information in the Painting Instructions
(Document Number F.01U.089.231).
Installation/configuration notes in accordance with
VdS/VDE/DIBt
• Planning for multisensor detectors follows the
guidelines for optical detectors, unless a specific VdS
planning guideline is available (see DIN VDE 0833
Part 2 and VDS 2095).
• The OC and OT types are planned using the
guidelines for optical detectors if operated as optical
detectors or as combined detectors; see DIN
VDE 0833 Part 2 and VDS 2095.
• When planning fire barriers according to DIBt, you
have to use the FCH-T320-FSA. This detector has the
characteristic curve corresponds to class A1R.
