Check 70 Trouble

Bell supervision trouble...check your siren/bell wiring...or just see if the siren/bell runs.

True. Also, if the red jumper has been cut the gentleman will need a 1K-Ohm EOL resistor across the siren terminals. The factiry default (jumprt uncut) is an unsupervised output.

Note to newbies: Do NOT install the EOL resistor inside the panel. Place it at the siren location.

Thanks. I never thought to look in the Addendum sheet dated 2/98 until you mentioned it. Yep, there it is. CHECK 70. Trouble is I never cut that jumper or connected a 2k resistor to the speaker. I know I'm senile but not that bad.......yet. I must have shorted something when I disconected the power to the driver.Thanks again, Crash.

Chexk 70 I think is bell circuit supervision.

You can, but that's not the purpose of the EOL or the jumper on that panel. The output is 12VDC. Hook it directly to a speaker and you'll probably just ruin the speaker. ABIK, the Vista-10SE should only be used with a siren, strobe or bell since there's no on-board siren driver.

Occasionally people get confused about supervision when using separate siren driver and horn (speaker). In that case the EOL can be installed across the bell output terminals (3 & 4 in the Vista-10SE). The speaker itself does not get an EOL resistor.

For clarity, some siren drivers provide a speaker supervision output. Usually it's a low current trigger that goes low (sinks

Well that's kinda what I meant...I guess you could supervise the 4" piece of wire going to the siren driver...but I doubt you could supervise a speaker without damage to something.

Agreed. I explained for the benefit of the other gentleman. I realize you already know all this stuff.
