Recognition of multiple codes
In some cases 3 valid codes must be entered within 2 minutes----e.g. to open a bank safe door or similar. Connect
as per figure 48, and program as follows.
Event-Actions
The
Recognized user code
events that refer to the codes must be programmed as follows:
Outputs ON
Ø
Recognized user code 1:
Output (OC1)
Ø
Recognized user code 2:
Output (OC2)
Ø
Recognized user code 3:
Output (OC3)
Program the
Alarm on zone
event that refers to terminal [Ly] as follows:
Outputs ON
Ø
Alarm on zone (Ly):
Output (OCx).
Zones
Program the zone that corresponds to terminal [Ly] as follows:
Ø
Alarm
Ø
Type:
24h
Ø
Balancing:
Normally closed
Ø
Sensitivity:
Standard - Pulses 1
Partition:
must be assigned to a partition that is not used by keys, codes or to control operations----this partition
can be considered a Technical partition.
Outputs
Outputs corresponding to terminals [OC1], [OC2] and [OC3] should be programmed as follows:
Ø
Type:
Monostable
Ø
Attribute:
Normally closed
Ø
Time:
ON time - 2 Min.
Program the output that corresponds to terminal [OCx] as follows.
Ø
Type:
Monostable
Ø
Program
Attribute
and
Time
as per requirements.
+
Connections and programming done: activation of output [OCx] will generate the following events:
24h alarm on
panel
,
Generic alarm on panel
and
Tamper alarm on panel
. To avoid false alarms----these events
must not be assigned to actions.
The door of a bank safe----connected and programmed in this way----will open when terminal [Ly] opens; that is,
when terminals [OC1], [OC2] and [OC3] open simultaneously. These terminals will stay open for 2 minutes, and
the codes must be entered within this time. Otherwise, an output will close to ground and block terminal [Ly] and
consequently----terminal [OCx] which controls door opening.
