Error and tamper monitoring
The sounder continually monitors error and tamper states and reports all events to the alarm panel.
The following is monitored:
•
Tamper contact:
The sounder’s tamper contact is continually monitored. The sounder activates itself in the
event of tampering.
•
Battery voltage:
The sounder monitors the battery voltage under load conditions, reports faults to the alarm
panel and sends a report if the remaining battery life is still about one month.
•
Supervision
The sounder continually sends supervision messages to the alarm panel
•
Signal jamming:
If a jumper is set to “Jam Det” (jamming detection), jamming monitoring is activated and the
sounder monitors attempts to jam the wireless signal. (See
Jam Det
description.)
If jamming
is detected, the message “Signal jamming” is sent to the alarm panel.
Danger
The sounder was designed so that changes are detected if they last at least 400 ms
(EN50131-1 Chapter 8.9.1 and EN50131-3 Chapter 8.9 and Annex B).
Breaking and entering, intrusion and tampering signals must last at least 400 ms.
The sounder was designed so that changes to the fault status (fault signals) are
detected if they last at least 10 s (EN50131-1 Chapter 8.9.1 and EN50131-3
Chapter 8.9 and Annex B).
Time conditions
The sounder was designed so that changes are detected if they last at least 400 ms (EN50131-1
Chapter 8.9.1 and EN50131-3 Chapter 8.9 and Annex B).
Breaking and entering, intrusion and tampering signals must last at least 400 ms.
The sounder was designed so that changes to the fault status (fault signals) are detected if they
last at least 10 s (EN50131-1 Chapter 8.9.1 and EN50131-3 Chapter 8.9 and Annex B).
Factory Defaults
If the sounder is taught-in to the alarm panel again, it discards all previous links. This causes the
sounder to return to the factory default.
