4.16 - External siren with wired
connections
4.16.1 - SPECIAL WARNINGS
Install the product in a location difficult to reach, to avoid intentional damage, possibly
in a location where the sound produced can be propagated efficiently in the required
directions. If necessary, fit additional sirens.
4.16.2 - PRODUCT DESCRIPTION AND INTENDED USE
HSSOC is an external wired siren with a sound power of 116 dB; designed to signal
intrusion and also to dissuade intruders.
Powered by the control panel, it envisages a backup battery (12 V 2,2 Ah) also for oper-
ation in the event of a power failure; suitable for outdoor use.
Any other use is to be considered improper and is strictly prohibited! Nice declines all
liability for damage resulting from improper use of the product and other than as speci-
fied in this manual.
4.16.3 - INSTALLATION
For installation procedures, refer to the relative instruction manual.
4.16.4 - PROGRAMMING
HSSOC does not require special programming. However, 2 settings are required before
marking the electrical connections:
a) TC block command: positive (+) or negative (-); for control panels HSCU1C and
HSCU1GC leave set to +.
b) Alarm signal block: after 3 or 5 alarm cycles.
4.16.5 - ELECTRICAL CONNECTION TO CONTROL PANEL
To make the electrical connection to the control panel, refer also to chapter 5 in this
instruction manual.
BATT +/-: electrical connection to backup battery. The back-up battery Pb-12V
2.2Ah (not supplied) is indispensable for siren operation.
P.SUPPLY +/-: electrical power supply connection from control panel ( P.SUPPLY - =
GND; P.SUPPLY + = +SAA)
+ N: positive "on absence" which activates the alarm (if block is not present on T/C).
TAMPER: output (voltage-free contact) for tampering alarm, for tamper alarm input
connection on control panel (between GND and TMP A or B or C). Otherwise the
tamper contact can be connected in series to + N.
T/C: block command, for connection to control panel armed/disarmed signal (+OFF).
For electrical connections, proceed in the following sequence:
01.
(model HSSO)
02.
03.
04.
05.
4.16.6 - OPERATION
HSSOC signals intrusion with a powerful acoustic alarm. On each alarm trip from the
control panel (+N), it emits an alarm signal lasting approx. 3 minutes; the alarm signal
terminates when the control panel is deactivated.
If the "alarm block" connection is envisaged (T/C connected to +OFF of control panel)
when the control panel is off, the siren is "blocked"; i.e. even if the alarm is activated
(+N), no acoustic signal is activated, which normally occurs when the control panel is
ON.
Also, for each control panel arming phase, the acoustic signals occur each time the
alarm (+N) is armed, only until the programmed count is reached; the siren is then
blocked when this number is exceeded.
The cycle count is reset when the control panel is switched off.
Luminous signals:
• 4 flashes = confirms arming of the control panel
• 1 flash = confirms disarming of the control panel
b
a
connect the battery: the lamp starts flashing (it remains lit if the battery connection
is inverted).
connect the power supply to the control panel: P.SUPPLY + and -:
connect the activation signal +N: the lamp starts flashing immediately and 2
acoustic signals are emitted for approx. 2 seconds to confirm the siren standby
status.
connect the tamper output
if present, connect the T/C alarm block command
