Tim Posted February 18, 2007 Posted February 18, 2007 I have a Securit 700L PLUS Panel (from C and K Systems) which was an original fit to the house. The original bell box had a problem with teh tamper and after 10 years I thought worth a replacement. I purchased an IntelliSense AG3 external sounder/strobe and have connecte dup as follows: Panel Siren Wire Colour -R RTN - BLUE BELL + HOLD + RED/WHITE (2 CABLES JOINED) BELL - OFF - BLACK -S TRG - YELLOW -ST STB - GREEN I have tested the system fully (alarm sounding, tamper on bell) LED's sounder alternating red/green but the strobe does not appear to work. Is it possible that the control panel is at fault? Can I test this in some way? Is there a way I can trigger the strobe directly from the sounder (ie by grounding -ST for example?) to see if the strobe it actually works? I understand I have to be careful with the DC voltage. Many thanks, Tim.
Tim Posted February 18, 2007 Author Posted February 18, 2007 have you tried temporarily linking the strobe and bell trigger to check the bell box is ok? I have set the bell off using the control panel (function CODE *9). The siren goes off but no strobe. I have linked s- [TRG] and ST- at the control panel. NOt sure if that is what you meant. No luck with the stobe anyway.
kka Posted February 18, 2007 Posted February 18, 2007 put the strobe - onto the siren trigger by its self, you know the siren is working. if the strobe is not working after doing this, then logic says the strobe is not working. return the unit and get a new one. had this problem with a new box on a nexas 8 panel. wired the new one the same as before and it worked, never assume because its new that it is in good working order.

Mmm. Looks like its a faulty strobe. Will get a replacement siren.
Tim Posted February 19, 2007 Author Posted February 19, 2007 yes thats what i mean but if thats hasnt worked then strobe looks faulty. get a replacement unit from the place you bought it from.cjt Just in case anyone has the same problem here is the solution (not tested yet). The Intellisense AG3 comes in a number of versions but with the same common circuitboard. It appears mine came from Ventcroft. With the "CLASSIC" model normally the STB+ should not be in teh circuit block however, for a short period of time some "CLASSIC" models were fitted with a better circuitboard. The instructions for the classic say "don't connect STB+" but in fact, it must be connected to a +ve. The fix is to either tap from HOLD+ or use STB+ from the control panel if available. Hope that helps !

Hope that helps ! Well The Securit 700L is trying my patience ! Cannot get strobe to work with what I beleive is the correct wiring. I have tested the strobe by hooking up HOLD+ to STROBE+ in the siren and then linking bell -ve to strobe -ve in the panel. BINGO !! The strobe flashes. However hooking strobe -ve from the siren to the -st in the panel does not flash the strobe on an alarm condition. Can this kind of fault appear in teh panel ? I tried hooking -strobe from siren to -s (bell negative trigger but that didn't flash strobe on alarm either. Is it remotely possible that the Intellisense Siren has different voltage requirements to trigger? I'm totally confused. Any suggestions appreciated !!
Guest Posted February 21, 2007 Posted February 21, 2007 Faulty cable by the sound of it, assuming when you put the links in in the panel the sounder still sounded.
Tim Posted February 21, 2007 Author Posted February 21, 2007 Faulty cable by the sound of it, assuming when you put the links in in the panel the sounder still sounded. Good point and I'll certainly test but why if I took the stb-ve cable in the panel and touched it on bell -ve would the srobe flash (no siren). I presume that means the circuit is fine. Connecting stb -ve back to stb-ve terminal block in panel doesn't work when siren sounds.
Guest Posted February 21, 2007 Posted February 21, 2007 Maybe not then. Sorry, couldn't quite follow what you'd done.
Tim Posted February 21, 2007 Author Posted February 21, 2007 Maybe not then. Sorry, couldn't quite follow what you'd done. No problem at all. I'm pleased to be able to bounce ideas around and I appreciate people taking the time to help me. I will double check all the wiring though although my gut says something is up with the panel. I don't want to give up too quickly but my next question will probably be a recommendation for a replacement for the 700L.
