20 Most Recent DSC Universal Accessories - P/N PTD1640U-CC Questions & Answers

The PTD1640U output is 16 volts AC (alternating current) so there is no polarity to the wires. You can hook either wire to either terminal on the wall transformer.

Check the Output specifications on the transformer in question and note the power output or 'Secondary' format. If it is listed as 'VAC', then the transformer can be wired either direction, as it provides a low voltage ( 16.5 VAC ) alternating current power source for the alarm panel. If it provides 'DAC', polarity WILL matter and you may have to have a professional check your installation.

I believe they have been discontinued but I have 16V transformers.

Either there is a fuse blown to.thevaux power or the wire has come loose from the terminal or there is a broken wire. Lastly have you checked to see if the transformer is still plugged into the outlet?

Could you maybe look for a brand and model on the system? Either on the keypad or on the system box (metal panel somewhere in the house)?

Then maybe Google the brand and model, looking for a manual?

The code is specific to your device and would ordinarily be known by the person that installed it
