User Manual
Version 5.3
6.1.6 Reset key:
Even when the conditions that had conduced an alarm disappear, the FIREWALL remains in that state until the reset key is pressed. This action
is not needed with fail conditions because once they disappear the FIREWALL will leave that state.
Note:
Action only available with level 2 access (after the input of the access code or key).
6.1.7 Delay Mode key:
This key allows to activate/deactivate the Delay Mode. In this operating mode, a (configurable) delay time is considered between the detection
and the indication (through auxiliary outputs, sounders, relays). This delay allows the user to verify if it is or not a false alarm, and act conveniently.
It is also possible to use this key when occurring the delay count-down to force the alarm immediately.
Note:
Action only available with level 2 access (after the input of access code or key).
6.1.8 General Alarm indication LED:
This red LED indicates a fire alarm. It is permanently ON during a fire alarm, and blinking during delay countdown (in Delay Mode).
6.1.9 Main-power indication LED:
The presence or absence of main-power is indicated by this green LED. It is permanently ON when main-power is present and blinking when a
problem is detected.
6.1.10 24VDC fuse indication fail:
The 24VDC outputs are fuse protected. When the maximum specifications are not respected, the fuse opens the circuit and the yellow LED will
indicate it.
6.1.11 Earth circuit fail indication:
The FIREWALL
is capable of detecting earth leakage currents from 1mA. When it occurs the yellow LED indicates it.
6.1.12 Battery presence indication LED:
When the secondary power-supply (battery) is not present, the yellow LED will indicate such fail.
6.1.13 Battery charging indication LED:
When the battery (secondary power-supply) is not fully loaded, the yellow LED will indicate that the battery is charging, until it is fully loaded.
6.1.14 General Fail indication LED:
Every time a fail occurs, this LED will be ON.
6.1.15 Sounder fail indication LED:
The output for external sounder is monitored to detect fails. When a short-circuit occurs, the LED blinks fast, and when an open-circuit is
detected, the LED blinks slowly.
6.1.16 Sounder fuse fail indication LED:
When the maximum specifications for sounders output is not respected (500mA), the fuse opens the circuit to prevent damages. When this
happens the yellow LED indicates it.
6.1.17 Disabled indication LED:
When any functionality of the FIREWALL
is deactivated (a zone, for example) this LED indicates it.
6.1.18 System fail indication LED:
The FIREWALL
has a microcontroller that controls all the system. When it fails, it will be indicated through this yellow LED.
6.1.19 Access level indication LED:
This LED remains ON while the FIREWALL is in level 1, blinks fast when someone is entering access code and blinks slowly when in level 2.
Note
: After entering level 2, if nobody presses any key for 1 minute, the FIREWALL
goes back automatically to level 1
.
6.2 Fire Alarm Panel Control:
It is possible to change several functionalities using the front panel keys. While some functions are directly available, others are only accessible
by entering an access code or turning ON an access key. These two access levels are called level 1 and level 2.
6.2.1 Introducing access code to level 2:
1.
Press
Buzzer
key for 2 seconds (approx.).
2.
Keyboard
LED starts blinking fast, indicating that the control unit is waiting for the input of the access code.
3.
Enter the access code. The default code is
Buzzer
,
Sounder
,
Sounder
,
Buzzer
.
The user has 7 seconds between keys to enter the code. If
this condition is not satisfied, a beep will be emitted and the user has to start from step 1.
4.
Press
Z1
key to validate the entered code.
5.
If the entered code is correct, a double beep will be emitted and the
Keyboard
LED will start blinking slowly. If the entered code is not correct,
the
Keyboard
LED will be permanently ON indicating level 1.
6.
To leave level 2, press
Buzzer
key for more than 2 seconds (approx.). Otherwise, if no key is pressed within 1 minute, the control unit will
enter level 1 automatically.
Note
: The default access code is Buzzer, Sounder, Sounder, Buzzer. To change the default access code to a new one please
proceed as described in point 7.1.1. After step 1, and until the entered code is accepted or rejected, the internal buzzer is automatically
muted.
