Trigger inputs 1 and 2 on the rear panel may start alarm or time signals upon closing its contact. The zones for

trigger 1 can be set with S302 (bit 1 to 6), for trigger 2 with S303 (bit 1 to 6). The selected zones receive a time or

alarm tone when the trigger is activated. Time tones are edge triggered and last the duration of the chime. Alarm

tones are level triggered and last until released.

(bit 3 and 4) and S303 (bit 7 and 8). If you use a LBB 1941 call station, the chime tone must be set with S301 (bit 6

to 8). You can find the chime tone tables at the end of the manual. With S301 (bit 5) the 2-tone chime on the DIN

priority contact for mic/line can be enabled or disabled. The 2-tone chime is 554 Hz (1s), 440 Hz (1s). You can set
