Difference between Active and Passive Alarm Monitoring
17 October 2019

Do you wonder how are the signals sent and received in our alarm monitoring system? Let's explain it below:

Our monitoring system, as being ULC consistent, is utilizing active and passive types of communication perceived inside the CAN-ULC benchmark which is referenced inside the Fire Code and the Building Code. We utilize these perceived types of communication and is always prepared to monitor your alarm system in various ways enabling us to adjust to any conceivable situation.

Active Alarm Monitoring

In active alarm monitoring system, the communication network between your building and our Signals Receiving Center (SRC) is vigorously directed by the SRC. This direction is done at regular intervals with an affirmation between the monitoring transmitter in your building and the SRC. This implies that if a communication failure occurs between your building and the SRC, our dis-patch will be told about it within 180 seconds. If this communication failure has not been re-established within 5 minutes, the ULC-S561 benchmark entails us to tell you about this failure. On the off chance that the communication failure proceeds, your system will be put on "manual-watch" implying that if an alarm is activated, somebody on location must go through some verification steps.

Systems utilizing active monitoring form include:

  • Cellular
  • IP – given that a 24-hour battery back-up is available

Systems utilizing active alarm monitoring are characterized as very steady and very little administration interruption. 

Passive Alarm Monitoring

Passive alarm monitoring is basically characterized as less customary supervision of the communication channel between your building and the SRC. In a passive monitoring situation, the check-in is accomplished once on daily basis at a foreordained time. Types of passive monitoring include:

  • Phone line
  • Cellular
  • IP

You can consider active alarm monitoring as less secure option. A passive system getting an affirmation and after that encounters an interruption would not be distinguished until they miss their next planned registration. Testing times can be day by day, week by week, or some of the time even month to month.

When fire or security alarm monitoring requires more elevated level security in passive monitoring situations, dual-way monitoring is required. According to CAN/ULC-S561, two non-redundant types of communication should be available when utilizing passive types of communication. In this type of setup, each line of communication monitors one another. In this way, if one of the lines gets failure, the monitoring station is exhorted by the other which affirms its operation. For instance, when a telephone line is interrupted, cellular communication acts as the subsequent way conveying a signal to the monitoring station and exhorting that the telephone line is missing. Signals can be sent or received from that building very easily even if the cellular communication is disconnected.
