Micromon
The Danfoss AKM has been updated to allow it to receive alarms from m2
units. However the m2 alarm dialout procedure differs from the Danfoss
Gateway in that it is not as tolerant of faulty telecommunication equipment.
The m2 would make repeated calls to try to transmit the alarm message up
to a maximum of 8. This conformed to the current telecommunication
regulations when the procedure as defined.
AKM will continue to try to transmit the alarm indefinitely. It can also control
the power to the modem using one of it relays. It does this after ten failed
attempts to dial-out and every 6 hours.
The 'AKM' call type has been created to mimmic the same dialout as the
AKM.
The m2 has two relays that are normally used for alarm indication. The
Relay 2 (REP ALARM) can be used to control the modem power. The
Relay is rated at 24V 1A max, so the low voltage power after the mains
transformer must be switched. Mains voltage MUST NOT be connected to
this relay.
