Zone Wiring

("1" in Figure 2.)

The control panel has a set of eight on-board terminal

blocks for the connection of alarm sensors, such as

door contacts and PIR detectors.

Each terminal block can connect to one or more

sensors, wired using either the double-pole (also

known as Closed Circuit Loop, CCL) method (see

Figure 4) or Fully Supervised Loop (FSL) method (see

Figure 5).

Figure 5: Zone Wiring (FSL)

By default, alarm contacts are normally closed. When

programming zones with normally-open contacts give

them the "Inverted" attribute.

The FSL method uses resistors at the end of the line

and across the alarm contact, which enables the cables

to be supervised for short-circuit or open-circuit

conditions to guard against cable tampering. The

resistors can have the values shown in Table 1 (the

values used must be specified when programming the

zone).

Table 1: Resistors for Zones Wired using the FSL Method

When using the FSL method, two cores are used for

each zone. When using the double-pole method, four

cores are used.

It is recommended to use only one detector per zone,

otherwise when an alarm or tamper condition arises,

the source of the alarm/tamper is not known.

If you are powering devices such as PIR detectors from

the control panel, an additional two cores are required

for connection to the 12Vdc power output terminals

(labelled "16" in Figure 2).

Whichever method is used, the wiring resistance must

be less than 100 Ohms (with the end-of-line resistor

shorted in the case of the FSL method).

If you are not using a zone, you should program the

zone as "Not Used".

Anti-Masking Zone Connections

Some PIR detectors are fitted with an anti-masking

facility to detect cases where the detector has been

obscured. Depending on the type of detector, the

masking status is conveyed by one of two methods:

• By an open/closed contact wired to a separate

zone programmed as type "Masking". Two zones

are therefore needed: one for the masking status

and the other for alarm/tamper status.

The sensor can connect using the double-pole or

FSL method. If double-pole is used for the Masking

zone, the zone's tamper terminals must be shorted

at the panel.

• By a specified resistance value to a zone (e.g.

Normal Alm or 24 Hour). The zone must be wired

as shown in Figure 6, which also shows the

resistance values used to convey the normal,

alarm, masking and tamper status. The zone must

have the "Masking" attribute.
