Plug-in Compatibility Link (LK3)
Some newer alarm panels use pin 11 as the ATS Test function on the plug-in connectors, whilst older panels may use pin
16 as alarm 8. GSM STU EV is supplied with an NVM (IC10) programmed and fitted to enable ATS Test mode
(see page 18). The jumper, at LK3, is fitted as supplied, to enable compatibility with plug-in panels using the ATS test
feature (SK2, pin11 connected to pin alarm 8 for ATS test).
Set the jumper in the lower position for use with older plug-in panels that use SK2, pin 16 as alarm 8. For stand-alone
(wired) installations the setting is irrelevant.
Output Relays
Three output relays are provided: Control, Return Path Signalling (RPS), and Line Fault.
Note : If an output is to be connected to a device which produces transient voltages, such as a bell, the device should be
suppressed using a suitable protection diode. Each relay’s contacts (Normally Open, Common, Normally
Closed) are available for connection on terminal block TB1. The relay contacts have a maximum current rating of 1 Amp.
GSM STU EV can be programmed to indicate communications path failures in different ways. Available options include
the
Line Fault Relay
indicating that both paths have failed (default); the
Line Fault Relay
indicating that one of the two
paths have failed; or landline and GSM path failures may be indicated on a combination of two of the three available
relays. These alternative modes of operation are not suitable for a GSM STU EV used as a plug-in.
