(SPLO) – SPARC-II connector line output
The SPARC-II connector is the middle D-SUB 15 female connector on the left rear side (see Section “Interface
connections” in the installation section). An auxiliary line output can be used to connect an external audio
amplifier. Received voice is always routed to this output. The received audio line output in the SPARC-II
connector contains any received voice signal. The receiver audio output is located on pins 14 and 15 in the
connector.

button or run the alarm test from
SPLO-02 Verify received voice data
Pass:
Voice signal is measured OK
between pins 14 and 15. Fail: No
signal measured on option pins 14
and 15

(HSC) – Handset connector flow
The handset connector is the lower D-SUB 9 connector on the rear left side of the transceiver (see Section
“Interface connections” in the installation section). The handset connector validation – if problems with the
handset are identified - is best done using a new handset or test equipment emulating a handset (see also
section “Handset block” description).
