1.
Location: It is recommended that the device be installed at the highest
point (e.g. motor room or top of shaft)
2.
Connect the GSM antenna to the SMA connector being careful not to
over-tighten. The antenna should be placed a minimum of 3 metres from
the GSM unit
3.
Insert the SIM Card into the SIM holder. Be sure the SIM is inserted in the
correct orientation with the gold contacts facing downwards.
4.
Connect the Emergency Telephone to the TEL1 connector. If connecting
more than one emergency telephone, either daisy chain the connection
between the telephones or use a junction block to split the connection
from the device.
5.
Connect the power supply cable to the GSM (see ‘POWER’ below).
6.
Turn the GSM Gateway on using the switch on the side.
It is possible to connect up to eight Memcom
+
Emergency Telephones to
the GSM; however a power connection should only be made to one of
these Memcom
+
units.
The battery 12V power supply from the Memcom
+
is used to power the GSM. The power cable provided has a
+12V core sleeved red, and a 0V core is sleeved black. This cable is then connected to the travelling cables to take the
power supply to the GSM terminal. The maximum resistance for each core is 1ohm. Use more cores in parallel if it is a very
long run and the resistance is higher than 1ohm.
A grey connector is provided with the GSM to allow you to make the connection to the Memcom
+
(see above ‘Power
Supply Connection on Memcom
+
).
NOTE: If you require a GSM suitable for use with other Emergency Telephones see the Avire ‘3G Universal GSM’ (part
number 452 003
