Indication LED description
The schematic shows the control keyboard and the
indication plate of a 6 zone BS-1636 panel. Starting from
the top left side we can see 4 indicators marked
'General'.The 'Disable' LED lights in every DISABLE
condition.
The 'Test' LED lights in every TEST condition .The panel
does not have a test condition as specified in paragraph
11 of EN 54-2.
The 'Fault' LED lights in every FAULT condition. Blinks
when we have a FAULT condition and the buzzer is
silenced. The 'Alarm' LED lights when we have an ALARM
condition. Blinks when we have an ALARM condition and
the buzzer is silenced.
Below is the indicator “POWER” which is on when the panel is working and blinks when there is mains supply
failure.
On the right of the “POWER” indicator is the “Delays ON” indicator which shows if the delays of the output are
enabled or disabled.
Below the `General` indicator group we can find the indication group called `Fault`.
The 'Battery ' LED and 'Mains' LED in combination, show us faults concerning the power supply. These
combinations are shown in the panel below.
The 'System LED lights to indicate a problem with the main processor unit (System fault).

The LEDs marked 'Siren1' and 'Siren2' correspond to the siren outputs. If a siren out has a short circuit or open circuit
then the corresponding LED will blink. If a siren is disabled the corresponding LED will light.
The next group of indicators is the 'Alarm' indication LEDs.
These indicators light when a corresponding zone issues an ALARM condition. Next to this group we have the
'Fault/Disable' indication for each zone. When the panel monitors an open or short circuit condition in a zone then
the corresponding LED will blink. If a zone is disabled the corresponding LED will light.
Control keyboard description/operation
The panel is controlled/ operated using the six numeric keys (1 to 6) found on the front panel. When a key is pressed a
short tone is issued.
The panel has three access levels.
Access level 1:
has all the functions that can be done directly from the user without using a code. These operations are:
Buzzer silence / Buzzer reactivation: If an alarm of fault condition is issued then the internal buzzer will sound.
Pressing the key "1" will silence the buzzer. ( The buzzer sounds periodically once every minute.) Pressing this key
again will reactive the buzzer.
Lamp test: Pressing the key "2" a lamp test is conducted by lighting the LEDs. The panel then returns to normal
operation. The above tests can be conducted only if the panel is in quiescent state (No fault or alarm conditions).
Override Delays: If an alarm occurs and the delays are active the user can overrride the delays by pressing the key “4"
. The output will be immediately activated.
