Type Description

AP 256 AP 256 fire combination alarms

The fire combination alarm with integrated bus coupling unit can

be used for the early detection of fires in buildings that are not

required to use VDS-approved fire detection systems (VDS -

Verband der Sachversicherer - German Association of Insurers).

It is of modular design, i.e. it comprises a base with integrated

bus coupling unit and a sensor head, which can be removed,

e.g. for maintenance or overhaul tasks. Smoke and heat alarm

indications and the current temperature value are output over the

bus. It also automatically indicates whether the sensor is defective

or soiled or whether the sensor has been separated from the

base.
