Two In/Two Out multi-function module by System Sensor combines two relay outputs and two monitor inputs.
The System Sensor Two In/Two Out multi-function module combines two relay outputs and two monitor inputs into one device. The module 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. There is a dedicated LED on the module for each input and output. The control panel can use these bi-color LEDS to indicate normal, alarm, and trouble conditions. This module is ideal for areas where inputs and outputs are needed in the same location. This could be used for smoke/fire dampers, HVAC fan, nondedicated smoke fan, dedicated smoke control, or even security doors. The two input/two output module is the same size as standard single modules. It can mount directly to a 4-in. square electrical box, to the surface-mounted SMB500, or into a DNR(W) duct housing.
