The Zone status depends on several parameters (refer
to “Zones” in the “PROGRAMMING FROM PC” sec-
tion). This section refers to the Balance type. If only this
parameter is considered, the zone status will depend on
the resistance between its terminal and negative, as
shown in Table 6.

Triple End of Line Supervision is ONLY available
on Grade 3 Control Panels and Input/Output Ex-
panders.
The following paragraphs describe the connections of
various types of detectors.

The Control Panels are supplied with the necessary
resistors to achieve the types of balancing sup-
ported: refer to “INTRODUCTION > Control Panel
versions > Grade 3 Control Panels/The Main Boards.

Connecting Motion Detectors
Most Motion detectors have Normally-Closed Contacts
(
NC
in the wiring diagrams), and Normally-Closed Tam-
per Contacts (
AS
in the wiring diagrams).
The wiring diagram depend on the selected supervi-
sion. This Control Panel supports the following supervi-
sion:
Ø
Normally Open;
Ø
Normally Closed;
Ø
Single End Of Line Resistor (SEOL);
Ø
Double End Of Line Resistor (DEOL).
Figures 11, 12 and 13 show the wiring diagram for each
Supervision type. In these figures:
Ø
[+] and [–] terminals represent the positive and nega-
tive terminals;
Ø
[NC] terminals are the Normally Closed Alarm Con-
tacts of the detector;
Ø
[AS] terminals are the Normally Closed Tamper Con-
tacts of the detector.
Normally Closed
The wiring diagram in Figure 11 il-
lustrates the connection of a detector to a Zone with
Normally Closed supervision.
Normally Closed supervision will allow the Control
Panel to detect Alarm status on the zone:
Ø
the zone will hold Standby status whilst connected to
negative;
Ø
the zone will trigger Alarm under all other conditions.
To provide Tamper detection on zones with Normally
Closed supervision:
Ø
either connect the detector tamper contact to the Con-
trol Panel Tamper Line — this type of connection does
not provide identification of the tampered detector;
Ø
or connect the detector tamper contact to a 24h zone
— this type of connection requires two zones — one
for Alarm detection, and the other for Tamper detec-
tion (refer to “Connecting Tamper Contacts”).
SEOL
The wiring diagram in Figure 12 illustrates the
connection of a detector to a Zone with SEOL supervi-
sion.
+
The 10 K
W
resistor must be connected to the last
detector of the zone.
SEOL
supervision will allow the Control Panel to detect
Alarm and Short-circuit on the zone:
Ø
the zone will hold Standby status when connected to
negative via a 10 K
W
resistor;
Ø
the zone will trigger short-circuit when connected to
negative;
Ø
the zone will trigger Alarm under all other conditions.
To provide Tamper detection: connect the Tamper con-
tact of the detector to the Control Panel Tamper Line, or
to a 24h zone (refer to “Connecting Tamper Contacts”).
