Short-time breaking the armed loop doesn’t cause the device to consider the loop condition as an alarm

if the time of breaking doesn’t exceed:

− 50 ms if the 300-ms Integration Time parameter is off

− 250 ms if the 300-ms Integration Time parameter is on

An alarm loop of the Type 4 switches from the Armed status to the Intrusion Alarm status if:

− The alarm loop has been broken for more than 70 ms, the 300-ms Integration Time parame-

ter being off

− The alarm loop has been broken for more than 300 ms, the 300-ms Integration Time param-

eter being on

− The loop resistance has jumped by more than 10%, the 10% Deviation Blocking parameter

being off for this loop

When the alarm loop has entered the Intrusion Alarm status then relay control in accordance with #1 -

#8 executive programs can be activated (if programmed).

If the parameter Auto Arming After Alarm is set on for the alarm loop then the loop will be automatically

armed and switches from the Intrusion Alarm to the Arming Delay status after its resistance being in the

normal range for a time interval more than 15 times value of the Alarm Delay configured for the loop (in

seconds).

Intrusion and Detector’s Tamper Alarms

The Signal-10 device can operate as an intrusion/detector tampering alarm control if at least one of its

alarm loops is configured with the Type 5. For such the loop the device can recognize the following sta-

tuses:

¾ Armed

¾ Arming Delay

¾ Arming Failed

¾ Disarmed

¾ Intrusion Alarm

¾ Short Circuit Failure

¾ Tamper Alarm

An alarm loop of the Type 5 is considered to be in Armed status if it has been armed and its resistance

is within the normal range (see Table 2). Short-time breaking the armed loop within the time intervals

not exceeding:

− 50 ms if the 300-ms Integration Time parameter is set off

− 250 ms if the 300-ms Integration Time parameter is set on
