OPERATING The output timing is activated by the alarm state (the alarm
state is not an output signal but is only an internal condition).
The activation of one alarm state Ak, Ah, Ap,or Af triggers the internal
buzzer signal with a delay "Ta" of 1 sec. The acoustic signal
due toAk, Ah and Ap shall have a duration "T" of 10 sec. With
50% intermittent sound and period 1 the acoustic signal due to Af shall
last till Af shall be active whith 50% intermittent sound and period 1
sec. The alarm output signal shall be interrupted during the period of
activation if the alarm state Ak, Ah, Ap or Af that caused the activation
ceases for a period of time longer than 0,5 sec.
To trigger a new output signal each alarm state Ak, Ah, Ap or Af shall
remain not active for a period of time longer than 0,5 sec. If at time
T=T1 of an active output signal a new alarm condition is generated, the
active period of the output signal shall be extended of a period
"T". |
