hi everyone kindly see my setup doc below ! tnx !
is the actual setup going to be OKAY ???
actually it worked, and still working since the last 4 days .. I want to energize the relay whenever EACH or BOTH of the devices closes contact ....

but i think the devices' internal contacts are not carrying both the load of the relay, i think it is only carrying the power supply (12V 1A) intended for the dpdt relay ONLY sir if i'm not mistaken . because the internal contacts of the device can only handle 15W contact rating, whereby the 2 output devices are rated at a total of 22W ... i'm triggering the internal contacts of the devices for more than 10 times a day , and nothing bad happens ...

i just want to know if it will last long without future troubleshooting .. but there will be of course as time goes by . and i also want to know where are these potential spots that will need troubleshooting in the future . tnx

It might be a good idea to insert a suitibly sized resistor in series with the relay coil as to minimize the current through it, check the relays datasheet and see what current they sudgest should go throu the coil. As it is now the relay activates but it might draw more current then is needed and that will put more strain on the relay then is actualy needed, then you should/can put a diode in parallel to the coil to handel the back emf when the relay stops being energized.
