LZ-01
Einbereichslöschzentrale
The LZ-01 single-zone extinguishing control center monitors and controls
single-zone extinguishing systems and can also be configured as an HRD
extinguishing control center. The rechargeable battery management and all other functions meet the requirements for EN-54 certification. DIN EN ISO 13849 PVL-“d“ categorization can also be achieved.Configuration is done via membrane keyboard and LCD display or via PC tool and allows a customer-specific coding of the access levels. The internal event memory can be read out through a USB interface.
The extinguishing control center equipped with four monitored signaling circuits works with a general status display via LED‘s and a detailed LCD status display. It has an internal buzzer, control inputs for monitoring ball valve and door contact, a test input for testing the safety function and a monitored 24V connection for external consumers. It also has KeyGen for generating access codes, an event memory, log memory and alarm counter, as well as ground fault monitoring. The control device can be mounted separately, e.g., in a control cabinet door and is connected via a flat ribbon cable with the base circuit board.

The lines L1, L2 and L3 trigger alarms, line L4 is used for the monitoring circuit, and triggers a malfunction |
Lines L1 and L2 can be configured in two-circuit dependency with variable gate time and buffer |
Lines L1, L2 and L3 can be configured as conventional or as HRD lines with or without alarm memory |
Lines L1, L2, L3 and L4 can be individually shut off (deactivated) |
For lines L1, L2 and L3 the extinguishing delay and the extinguishing time are configured separately |
