Smoke switch condition indicator RZA 142
Fig. 8-09 RZA 142, front view
The smoke switch status indication RZA 142 receives signals for and displays
the following statuses via the communication interface Pin 3 of the LRS 04 Ex:
operation, slight contamination, heavy contamination, fault or alarm. In addi-
tion to the visual indication, a potential-free change-over contact is assigned to
every status; the contacts are used to transmit statuses to higher-order systems,
(such as a central building control system).
If an RZA 142 is used in parallel to the LRS 04 Ex, the ORS 221 Ex must be
re-initialised after installation of after replacement in connection with this
RZA 142.
The RZA 142 is exclusively intended for installation in safe areas. The
RZA 142 does not have inherent safety.
