Bosch Solution 6000 x2 Piezo's in parallel

[Schnake]

Is it possible to run 2 screamers in parallel off the same output on a Bosch Solution 6000 system? Noting it would only be an additional ~200 ohms.

Also, I've just come to realise that the installation manuals suggests 3K3 resistor across the piezo. From what I've seen in my install there is no resistor (as in not installed by the installer) at least at the piezo end. Should I be concerned?

Hi

You can run two screamers off output 5.
Connect them in parallel one in com and one in NO terminals
Program out to follow alarms

Awesome. Thanks.

Though what do I program it out as?

• Off Low Battery
• Guest Control
• Reserved
• Monitor Overload
• Monitor Device Fail
• Alarm On Device Fail
• ...
• ...

So get into program mode go to menu 4-1-1 put event number event 38 number then put -
Black wire to -12v and then both red wires in to NO of relay on board.plance ju.per accross 12 postive near
relay o board arm system give it ago...

Sorry... I thought I understood you with the connections the first time, but now I'm confused.

So run a red wire from accessory postive to COM on the relay contact you mark in red pen then place both red wires from screammers to the
NO of the relay .then place black wires from screammers to power GND.program out and test

Got it! Makes sense. Thanks.

You should leave the screamers connected into Output 4 as per the diagram you have shown. The resistor serves two purposes:
1. The allow the panel to monitor if both screamers are connected/disconnected. (Note that both need to be disconnected for the "Monitor output fail" option to work, if programmed)
2. To stop the screamers emitting a faint sound due to voltage "bleeding" from open-collector Output 4

The Output type should be 37, NOT 38, contrary to the "advice" given by techy21, as type 38 causes the output to work even for silent alarms. Be very wary when taking advice from techy21......

So two screamers off output 4 plus a 3K3 resistor is the go. This is inline with my initial thoughts.
