GSM STU compatibility
For instances where the GSM STU EV is required to behave in an identical fashion to a GSM STU, the NVM should be
removed and the link LK3 be fitted to position P16. This mode of operation disables the ATS test functionality and
permits pin inputs 10 and 11 to be used if required.
3GSTU Replacement
The GSM STU EV has been designed as a replacement for existing 3GSTU installations where there is a need to upgrade
the line to incorporate GSM backup. For a 3GSTU-12V any existing alarm pin wiring or power connections can be
re-used. These terminals are in the same relative positions as they are on the 3GSTU . Any existing power supply needs to
be adequate, see page 6. Care must be taken when replacing a
3GSTU-PLI
because of the slight differences in the
plug-in connector pin-out (see page 15).
Redcare GSM Connection
redcare gsm requires that the designated ARC be connected to the redcare Digital Services Platform (DSP).
Safety Statement
The circuit board area, under the cover, is classed as a Telecommunication Network Voltage (TNV-3) circuit. All other
interconnection points are classed as Safety Extra-Low Voltage (SELV) circuits. It is only necessary for this cover to be
removed during installation of the PSTN wiring. A protective earth connection is required to the terminal block TB5.
GSM STU EV is designed for host-independent fitment.
The host alarm panel or box into which the
GSM STU EV
is installed must provide a RESTRICTED ACCESS LOCATION and a
FIRE ENCLOSURE in accordance with the requirements of BS EN 60950.
It is essential that the
GSM STU EV
is installed so that there is a gap of at least 5mm between it and any other part of
the host equipment (excluding the mounting face). If any part of the host apparatus uses or generates voltages in excess
of 250 V rms or dc, obtain advice from a competent telecommunications safety engineer before you install
the GSM STU EV.
