The wiring diagram for including fire heat (normally closed) detectors into alarm loops of the Type 3 is

presented on the page 65.

Intrusion Alarm Loop (Type 4)

A loop of the Type 4 (Intrusion) is intended to involve any intrusion detectors, both normally open and

normally closed, and powered either over the loop or separately. This loop is considered to be in one of

the following statuses:

Armed The alarm loop is monitored, its resistance being normal

Disarmed The alarm loop is not monitored

Arming Delay The programmed Arming Delay has not yet expired

Intrusion Alarm The alarm loop has been broken

Arming Failed An attempt to arm the loop has failed because the loop is broken

An Intrusion alarm loop is considered to be broken if its resistance goes out of normal range as well as

jumps by more than (provided that the 10% Deviation Blocking parameter is set off). Breaking an intru-

sion loop causes it to enter the Intrusion Alarm status.

An alarm integration time for this type of alarm loops can be 70 ms or 300 ms depending on the pro-

grammed value of the 300-ms Integration Time parameter.

Table 2 shows the matching between current resistance values and corresponding statuses of alarm

loops of the Type 4.

The wiring diagram for including intrusion detectors into alarm loops of the Type 4 is presented on the

page 65.

Intrusion Alarm Loop with Tamper Monitoring (Type 5)

A loop of the Type 5 (Intrusion with Tamper Monitoring) is intended to involve a single intrusion detector

and the tamper switch of this detector. This loop is considered to be in one of the following statuses:

Armed The alarm loop is monitored, its resistance being normal

Disarmed The alarm loop is not monitored

Arming Delay The programmed Arming Delay has not yet expired

Intrusion Alarm The alarm loop has been broken

Arming Failed An attempt to arm the loop has failed because the loop is broken

Tamper Alarm The enclosure of the disarmed detector has been tampered, or

short circuit failure of the disarmed loop has been detected
