Signal-10 Operation Principles

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 7.

The wiring diagram for including intrusion detectors into an alarm loop of the Type 7 is similar to that

presented on the page 65.

Panic Alarm Loop (Type 11)

All kinds of normally closed and normally open panic buttons, pedals and so on can be brought into a

Panic alarm loop (Type 11). 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

Panic Alarm Breaking the loop has been detected

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

ken

A Panic alarm loop is operated similarly to an Intrusion alarm loop, except this loop switches to the Pan-

ic Alarm status after it has been broken.

The Panic Alarm status is indicated only by the relevant Signal-10 LED and can initiate only that related

relay which is programmed to operate in accordance with Alarm Output 1 (#10) or Alarm Output 2 (#16)

executive programs (the relay contacts being opened). The internal sounder of the Signal-10 also is not

activated upon Panic Alarm.

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 11.

The wiring diagram for including panic buttons into an alarm loop of the Type 11 is similar to that pre-

sented on the page 65.

Programmable Auxiliary Alarm Loop (Type 12)

This type of loop monitoring methods can be used to monitor the conditions of various equipment and

detectors, including those which are not related directly with fire and intrusion alarms. Any detectors or

devices with dry contact or open collector outputs can be included into an alarm loop of the Type 12.
