7.2 Phone jack location

To prevent jamming of signals, wire the RJ31X or RJ38X jack before the premises telephone

system to support line seizure. Install the jack on the street side of the telephone switch,

wired ahead of any PBX equipment. Line seizure temporarily interrupts normal telephone use

while the control panel sends data. After installation, make sure that the control panel:

– Seizes the line

– Gets a dial tone

– Reports correctly to the receiver

– Releases the telephone line to the in-house telephone system
