Hi,
How long does the battery have to support the system in an alarm state? The Texecom calculator suggests that the total alarm load is 1.35A (and is happy with it; the battery fuse is 1.6A), at that current a 7Ah (at C20) battery will have a 5Ah-6Ah capacity so should be able to support the sounders for at least 3.5 hours (ignoring the bell time out).
I didn't think the bell input on the Odyssey carried the full current, I'll have to get my meter out and check.
From a fault finding perspective, being able to discriminate between the two tampers sounds like a good idea - my question was more around whether the Premier Elite can cope with both the traditional 0V tamper signal and the Aux/Fault input also being configured as a sounder tamper but I'm guessing it won't care.
None of the Premier Elite panels have a PIR LED output, the 24 has a single -ve switched output whilst the 48 has 2x -ve switched outputs and the bigger panels have 2x -ve switched, 2x +ve switched and a volt free change-over. The output functions are configurable with walk test being one of the options and are invertible (i.e. you can configure the output on, or off during the walk test). Since the IR model PIRs need a positive supply to disable then the obvious thing is to provide one through a resistor that the panel output can pull low when you do a walk test, I'm trying to pick the value of that resistor so that it can give enough voltage at the PIRs to disable them normally, but won't draw ridiculous current when doing a walk test. Given the 500mA output rating, I could go as low as 24 Ohm, but that would get rather hot during the walk test... Sounds like another job for the meter.
Thanks for your comments!
