Pyronix HomeControl+ to wired Deltabell

[bee_man]

I want to physically wire a Deltabell to a Pyronix HomeControl+ wireless alarm. Hopefully the attached picture is not too far off the mark. I think the 2K2 resistor is not relevant if it's just an ordinary input of type Tamper. I'm assuming PGM can drive Engineer Holdoff, and STB->STB, BELL->BELL is a wild guess :). Where I'm most unsure is what type to make the three outputs. Are STB and BELL already "pre-programmed" in that fixed function?. For PGM driving holdoff, I have read here to make the output of type Engineer Access. Looking at the output type table I find

 

0059     : Engineer Access

Active    : When entering Engineer mode.

Restore : When leaving Engineer mode

 

So far, OK, but the text above the table says:

Polarity of the PGMs: The polarity of the outputs are normally switched negative, i.e. normal status
OFF = 0v and in active status ON = 12v.
NOTE: The PGM Outputs polarity cannot be inverted.

 

So it sounds to me like setting PGM as type 59 and wiring it to the deltabell holdoff, holdoff will go to 12V when in engineering mode and the PGM output is active. This is the opposite of what we want, isn't it. Ie, you should take holdoff to 0V to inhibit the bell, not set it to 12V. Any thoughts please?

 

If I want to drive two deltabells, can I parallel up all except tamper, and wire that  from D1- to T1 on the first bell, out of T2 on the first bell into T1 on the second bell, and out of T2 on the second bell into Z33 input?. T1 one the first bell will be linked to 0V on the first bell.

 

Batt/PSU is a 9Ahr 12V battery backed 3Amp PSU/charger, in a metal box like RGL and others supply.

Can anybody advise please?. Thanks.

Better to set one bell to scb mode and second to sab , or whichever way round, 

 

As for resistor dont know the panel well but it's probably requires otherwise will keep showing bell tamper , resistor that comes with delta bell is explained in instructions 

 

And yes depending on panel you can use an output to control engineer hold off , but I don't I just know which leg it is and apply if and when required manually, on the delta that is

Thanks fro your help. Yes, I've seen the info about that terminating resistor and it is something different to this 2K2. The 2K2 I was referring to is in series with the tamper line as used in DEOL. I don't see why it's needed in this way of using it.

 

Yes, I've seen the recommendation for one in SAB and one in SCB if using two bells, but my main question on that one is why?. I'm using a battery backed up 12V supplt to the bells and rest of the equipment. The bells themselves will run off that 12V, and will charge their own internal battery from it, so they are independantly backed up if the 12V supply is cut to either or both.  I'll change them if I needed but I have to now the reason.

 

My main problem is silencing the bells when in Engineering Mode, via the hold up. The Pyronix  box has the ability to have an output set to type " Engineer Holdoff " meaning it goes high when in engineering mode. Unfortunately it seems to be the wrong polarity according to the installation manual which says the bell hold off input needs to be taken low to inhibit the siren. I take your point, I guess could do it manually.

Setting bells like that depends also on system output , current draw of bells and current output of panel

 

Current draw when bells are both going nuts and pulls the panel down because panel output wasn't strong enough 

 

You get it

Understood, that's one of the reasons I'm using a separate battery backed 12V power supply, so the 12V siren supply won't draw anything from the alarm panel 12V. As for the STB and BELL lines, I was under the impression that the siren inputs are just signal inputs taking a few mA, and the STB and BELL outputs on the panel can supply 500mA each, so I should be OK there. The current draw when it goes nuts will either be supplied by the battery backed external 12V supply or the internal SAB battery, not from the panel.

 

Unless I've missed something, which is entirely possible. . .

I wasn't talking about the triggers, so it should work, how will you monitor external psu ?

 

Perhaps 12v relays connected to zones in panel so you know when there's a fault

[bee_man]

I'm planning to use the 1205SM-2 power supply by RGL which has a tamper output, and there's an optional monitor unit for 12 quid which gives isolated relay outputs for Missing or No AC and for Missing or Low Battery. I can wire them direct to the inputs in the panel. The panel and it's inputs do not depend on the external 12V. I'll put the tamper straight to 24hr tamper input, but I suppose I'll make the other two chime at the panel and log the event.

RGL have problems with the add-on monitor board for the 1205SM 12V PSU at the moment, so I've changed to the CQR PSS12V2A/G3/C which looks very good quality. No way do I need grade 3! but it will do nicely. EPS, APS, PO and Fault/Tamper isolated outputs, 3 separate battery connectors with individual charging. Polyswitch resettable fuses, tamper front and back, space for two 12V 17Ahr SLA batteries or three 9Ahr, or you can get the medium sized /B box or the small /A. Also plenty of holes for tie wraps and cable gland holes in the base, knock outs top and bottom.
