SIGNAL-20P DESIGN AND OPERATING PRINCIPLES

This type alarm loop resolving time is 70 ms or 300 ms depending on

“300 ms Integration” parameter value.

The compatibility of loop resistance and the corresponding status can

be shown at the Table 3.

The diagram of connection call points and other alarms to the type 11

alarm loop is similar to the type 4 loop connecting diagram and is con-

tained into the Appendix E.

The type 12 is the programmable auxiliary alarm loop.

This alarm loop type can be used to control the variety of equipment,

among them the devices not dealing with burglary or fire alarming. The de-

tectors or devices with “dry contact” output (normally opened or closed), or

with “open collector” output are included in alarm loop of this type.

The programmable auxiliary alarm loop can have up to 5 various

statuses that are defined by loop resistance. One can program both

statuses and the corresponding threshold resistance values. In so manner

the equipment having several statuses and several associated output con-

tact groups can be monitored via one alarm loop by means of including the

contact groups into alarm loop complemented with additional or shunt

re-

sistances. Moreover one can control short or open failures of this loop.

Audible and light alarming and the influence of this loop on the relay

are defined by the statuses this alarms can have.

Status changing of the programmable auxiliary alarm loop depends

only on the alarm loop resistance changing and is not defined by any loop

parameters or arming/disarming commands.

The resolving time in case of status changing is equal to 300 ms. If

alarm loop is entering “Armed”, “Disarmed”, “Aux Zone Restore” or one of

recovering statuses then the transition has been considered as completed

after "Arming Delay" seconds.

The programmable auxiliary alarm loop is impossible to disarm, it is

monitored permanently. Having received the programmable auxiliary loop

arming/disarming command the device generates the current loop status

message.

Programmable auxiliary alarm loop status having been changed, the

corresponding messages are sent to the net controller (S2000/S2000-M

console or ARM Orion). These messages are not storied in nonvolatile de-

vice memory. So if during net controller disconnection several status

changes have occurred then when connection is recovered either only one

message would be sent to the net controller or no messages would be sent

if the current status is equal the last sent one.
