set by means of pins for inactive status. The 20-second delay prevents the alarm from being
accidentally triggered during installation work.
The maximum duration of acoustic signaling is set by means of the TM0 and TM1 pins (the fact that
the acoustic signaling control output of the control panel will be active longer is of no significance).
Triggering the acoustic signaling again will only be possible after the control signal is restored to its
status which preceded the alarm.
If the control wires are cut or the external power supply is lost, the tamper signaling is triggered
(signaling mode: pins O+A; signaling duration: pins TM0 and TM1).
The siren is designed for operation with a 6 V / 1.3 Ah lead-acid battery, but it can also work without
one.
Notes:
•
The battery charging system used in the siren is designed for recharging a partially discharged
battery, not for charging a fully discharged one.
•
The current consumed by the siren to charge the battery depends on the battery degree of
discharge.
