I bought the Honeywell AG6/WB ActiveGuard but am a little unsure of the
wiring in the present broken box as I haven't been up the ladder yet.

The new box expects five cores: TR- (negative tamper return), V-
(negative supply), ST- (negative strobe trigger), V+ (positive supply)
and S- (negative sounder trigger) but I suspect that when I get up the
ladder I will find just four cores with a strobe connection to the
Scantronic 9448 panel missing.

However, the instructions for the new box say that 'for panels without a
strobe output the ST- should be connected to the SW-'.

Three questions:
are S- and SW- one and the same (and just an inconsistency in the
instructions)?

and

if I do make the link, will the strobe activate when the sounder activates?

and

if the strobe will activate, would the additional power drawn by the
strobe be an issue?
