AL8-2  Alarm panel With eight digital alarm inputs

With eight digital alarm inputs, three relay outputs and many flexible features, the AL8-2 alarm panel

is suitable for alarm monitoring at industrial and marine plants.

Alarm inputs: the alarm panel is provided with eight alarm inputs to facilitate external mechanical alarm

contact connections. The inputs are individually programmable for N/O or N/C alarm contacts.

Time delay: the alarm inputs are individually programmable with a time delay to allow alarm condition registration

at pre-set times within the 0.40 s range in steps of 1 s.

Alarm indicators: the AL8-2 is equipped with eight LEDs marked 1 to 8 for precise indication of alarm conditions

for the individual alarm inputs. When an alarm condition occurs, the LED for the relevant input channel will flash

with a red light. If more than one alarm occurs before the push-button “LAMP RESET” is activated, the first alarm LED will flash ahead of the others.

Alarm outputs: the alarm panel is provided with three relay outputs, one of which is used for connection to an audible/visual alarm.

The remaining two relay outputs are individually programmable by the user to follow certain alarm inputs.

The alam panel is provided with 3 relay outputs, 1 of which is used forconnection to an audible’visual alarm,
The remaining 2 relay outputs are individually programmable by the user tofollow certain alamm inputs.
When the relays of i of these 2 outputs are activated, the relevant LEDmarked “A” or “B” on the front will be lit constantly (red bght).
The alarm panel is equipped with a LED marked “POWER ON” which when lit(green light)indicates that auxiliary voltage is connected and that theprocessor is active.
The user may for each alarm channel determine whether cable failure shallresult in an alamm.
Cable failure is indicated by means of the LED marked “CABLE FAILURE*(flashing, yellow light), The LED for the faulty channel will simultaneously be lit(constant, yellow light).
A cable failure results in activation of the relay output used for audible,visualalarm only.
The alarm indicalors and the alar outpuis “A” and “B” are reset by means ofthe push-button marked “LAMP RESET”.
On activation of this push-button, the alarm indicators will be lit with a constantred light, until the external alam conditions are cancelled.
When these have been cancelled, the alarm indicators are switched off andthe output relays are reset
