5. Fire Alarm Activation Input
The
“FIRE”
input is used to activate the siren in the event of a fire alarm. It is activated by
applying a voltage of +12 V and the siren sounds with a special fire detection sound.
Attention!
If the “TRIGER” and “FIRE” input are activated at the same time, the “FIRE” input
will have priority
6. Bypassing the Siren’s Tamper - Removing the Lid
“TC”
input (Tamper Control input) is used to deactivate the siren’s Tamper, when you open the
cover of the siren for service, without given an alarm. Connect “TC” input to a “PGM” output of
the alarm control panel, which provides 12 V at standby mode and goes to 0 when the panel
arm. The presence of 12V on this input disables the Tamper of the siren for 10 minutes.
In the Sigma Alarm panels, connect the siren’s TC input to a PGM, which must be
programmed as type 27.
7. Visual or audible indication input
The
“SIGN”
input is used when we want to have visual and / or audible indication of arming or
disarming the panel via the siren when, arming or disarming the system by remote control. It is
activated as long as there is +12 V at its input and is connected to a programmable output of
the panel (PGM) which is programmed accordingly.
In the Sigma Alarm panels, it must be connected to a PGM programmed as type 29.
8. Fault Output
The siren automatically monitors the battery status (Battery Self-Test) by dynamically testing
the battery, every hour when there is a voltage at the siren power input (+ 12V-) or, every five
minutes when there is no voltage. If, during the test, the battery voltage is lower than 11.5V,
we have a low battery voltage indication, and if the battery voltage is below 10.0V, we have a
battery failure indication. In both cases, the “FLT OUT” (Fault Output) output is activated.
The “FLT OUT” output is 0V and becomes Open Collector (OC) when the battery voltage is
low or the battery is damaged. Returns to standby again at the next test and if the battery volt
age rises above 11.5V or the battery is replaced with a new one.
This notifications are used to inform the user and / or the Central Monitoring Station, the
battery status of the system. A LED may be connected to this output or it may be connected to
the control panel, as shown in the siren wiring schematic.
For greater security, program the Control panel zone as a 24-hour EOL and connect the
terminal resistor in the siren.
9. Alarm Output
The
“ALR OUT” (Alarm)
output is activated when the siren triggers an alarm if its power supply
voltage from the Alarm panel is interrupted, or the foam, shock or 3-axis detector is activated.
The
“ALR OUT”
is activated simultaneously with the siren and is 0 at standby and becomes
Open Collector (OC) on activation. Used to update the system user and notify the Central
Monitoring Station for this event. You can connect it to a LED indicator or a zone of the panel,
programmed accordingly, as shown in the schematic that displays the siren connection.
For more safety, program the zone as EOL and place the EOL resistor of this zone inside
the box of the siren.
