Service manual AlphaCom PSTN2IP ML transceiver Rev. 1.6 10-09-2011 Page 27/65
The same programming logic of placing an alarm message in the buffer and activating the PSTN prio relay
on failure also applies for the
power supply failures
and
other
. In the AlphaCom PSTN2IP ML the
programming option for power supply failures is not supported. This is only supported in the AlphaCom
XL.
The settings for
tamper switch
apply for tamper switch S1 mounted on the AlphaCom PSTN2IP ML board.
This tamper switch can be used if the AlphaCom PSTN2IP ML is mounted outside the control panel casing.
It is advised to mount the AlphaCom PSTN2IP ML in the same casing as the control panel.
If the AlphaCom PSTN2IP ML is mounted in a separate casing then tamper switch S1 can be fitted with a
tamper spring. The appropriate SIA code should also be programmed in this screen. You must ensure that
the casing used for the AlphaCom PSTN2IP ML complies with regulations stated.
For the
PSTN tamper loop
a SIA code must also be programmed if the tamper loop option is used. When the
PSTN connection between the analog dialer and the CMK input in the AlphaCom PSTN2IP ML is
disconnected a alarm message will be sent to the central station.
