The Two In/Two Out multi-function module by System Sensor of St. Charles, Ill., combines two relay outputs and two monitor inputs into one device.
The module, which has a dedicated LED for each input and output, is capable of Class B supervised wiring to the monitored devices. It also contains Form C relay contacts allowing the panel to switch the contacts on command. The product can mount directly to a 4-inch square electrical box.
The base address is selected via rotary switch and assigned to relay output No. 1 from 00 to 156. The module will automatically assign the next three addresses as appropriate to monitored input No. 1, relay output No. 2, and monitored input No. 2. If relay output No. 2 or monitored input No. 2 are not used, it is possible to disable those addresses via DIP switch. Those two addresses will then be free to be used for other devices on the loop.
