Integrated inputs
DALMx000 has five “virtual inputs” that automatically activate in the event of different system events.
Event ”Input” Event code
Power supply < 10.5 VDC LowBatt 81
Internet connection error EthErr 82
GPRS/3G connection error GPRSErr 83
DALMx000 bypassed Bypass 84
Cover protection Sabotage 85
The integrated inputs are connected in the same way as the hard inputs to any receiver during system
programming and can be supplied with separate delays prior to activation.
GPRS Err is activated when the signal strength in the GSM network drops below level 6 (of a max 31) and
remains there during the set input delay. EthErr is activated either if the connection cable is removed or if
transmission of an alarm via fixed Internet fails, if the error is not reset before the programmed time delay
has expired.
Analogue alarm from dialer connected to ”LINE OUT”
After DALMx000 has been commissioned, the device can receive normal analogue dialled alarm
notifications from a dialer that is connected to screw terminal ”LINE OUT”. DALMx000 simulates a normal
analogue telephone line, receives numbers dialed by the dialer and send a start tone for SIA or Contact ID.
As a response to the start tone, the dialer delivers its alarm notification, which is decoded and converted
by DALMx000 and sent to the alarm receiver via SMS, E-mail or TCP/IP.
For alarms via TCP/IP, the following applies:
If the received analogue alarm notification is of Contact ID type, the alarm is acknowledged by an
acknowledgement tone to the connected dialer as soon as the acknowledgement is received from the
receiver.
If the received analogue alarm notification is of SIA type, the alarm is acknowledged to the dialer as soon
as it is received by DALMx000. If delivery to the alarm centre then fails, output REL1 on DALMx000 is
activated for of two seconds.
Note The above means that output REL1 should, when connecting a SIA dialler to DALMx000, be
connected to a section on the connected dialer so that a local alarm can be activated in the event of a
transmission problem.
