DEOL
The wiring diagram in Fig. 13 illustrates the con-
nection of a detector to a Input Line (Zone) with DEOL
supervision.
+
The 10 K
W
resistors must be connected to the last
detector of the zone.
DEOL
Supervision will allow the Control Panel to detect
zone Alarm, Tamper and Short-circuit:
Ø
the zone will hold Standby status whilst connected to
negative via a 5 K
W
resistor (i.e. using two 10 K
W
re-
sistors connected in parallel);
Ø
the zone will trigger short-circuit when connected to
negative;
Ø
the zone will trigger Tamper when open;
Ø
the zone will trigger Alarm under all other conditions.
+
Zones with DEOL supervision can detect and sig-
nal Alarm and Tamper by means of just two wires.

Connection of Grade 3 detectors
3
This type of connection is only possible with
Grade 3 Control Panels and Input/Output Expand-
ers (with firmware revision 1.10 and above).
It is NOT possible with keypad input expanders.
The wiring diagram in Figure 14 illustrates the connec-
tion of a Grade 3 detector to a Input Line (Zone) with
Triple End of Line
supervision (refer to “PROGRAM-
MING FROM THE PC > Zones”).
In addition to the contacts for signalling tampering and
alarms, Grade 3 detectors are equipped with a contact
that is normally closed for reporting faults, such as
masking (
Fault
in Figure 14).
Tripe End of LIne
Supervision will allow the Control
Panel to detect zone Alarm, Tamper, Fault and
Short-circuit:
Ø
the zone will hold Standby status whilst connected to
negative via a 2,2 K
W
resistance;
Ø
the zone will trigger short-circuit when connected to
negative;
Ø
the zone will trigger Tamper when open;
Ø
the Zone will trigger Fault when connected to nega-
tive with a resistance of 24.2 K
W
(i.e. the series of the
resistors from 2.2 K
W
and 22 K
W
);
Ø
the Zone will trigger Alarm when connected to nega-
tive with a resistance of 8.2 K
W
(i.e. series of the
2.2 K
W
resistor with the parallel of the resistors from
22 k
W
and 8.2 k
W
).
