GENERAL FEATURES
Two models of siren are available, different for the acoustic pressure:
HP305: Acoustic pressure 112 dB (A) @ 1 m, absorption 650 mA
HP305P: Acoustic pressure 117 dB (A) @ 1 m, absorption 2,2 A
•
Internal siren with different dual mode sounds management;
•
Controls managed by micro-processor;
•
Battery polarity inversion protection and power via control unit;
•
Block commands and TC with NC contact programmable with POSITIVE or NEGATIVE reference;
•
Sound block time out due to cable cut (4 programming steps)
•
Sound inhibition at first power-up;
•
Anti-opening and anti-removal protection (using a rawplug);
HP305 family sirens are equipped with two different signals, connected to BL1
and BL2 commands.
BL1 command is related to the alarm signal (f=2400-3600 Hz), subordinate to
the presence of TC signal, programmable time-out and alarms counting.
Once it is ready for normal operation, the siren will generate an alarm only if
both TC and BL1 signals are missing. The absence of one only of the two
signals will not cause any event.
To lock an alarm in progress, it is sufficient to re-apply the BL1 lock signal.
If there is another lack of BL1 a new alarm will immediately be generated.
If the lock command lasts longer than the programmed timeout, the siren will
stop automatically and a new alarm cycle will be generated only with the
following on and off cycle of lock signal.
The siren is equipped with alarm cycles counting function. If five alarm cycles are reached, any further alarm
cycle is locked. The reset of the counter occurs when the system is re-armed (TC signal present) or after 24
hours from the beginning of the lock.
NB: The cyclic counting is operative only if it has TC command. If the control unit has no TC exit,
connect the TC1 terminal strip with BL1. In that case you lose the cyclic counting function.
The BL2 command can be used for signalling pre-alarm, out of order, gong, etc. (f=1700 Hz), is independent
from the TC signal and it is not subject to the cyclic counter. In case of the absence of lock signal, it has a 30
minutes fixed time-out. To restore it, it is necessary to re-put the lock signal. For this command there are two
different available acoustic sounds (high or low), it is possible to select using a jumper (see
"CONFIGURATIONS"). In residential installations it is advisable to use low sound level.
To facilitate the connecting operation, the siren is equipped with initial block. At first power-up, the siren does
not blow (even if BL and TC signals are not present). After the power is supplied, the siren waits for the correct
presence of BL1,BL2 and TC signals from the control unit (respecting the choice made for the input type), so it
is ready for normal functioning.

TC is a command
generated by the control
unit to give the siren
information about the
state of the system
(armed or disarmed).
- When the system is
disarmed, on the TC1
terminal strip of the siren
there is a tension of
+12V-
- When the system is
armed, on the TC1
terminal strip of the siren
there is a tension of 0V or
"floating".
