2-In/2-Out Module Reduces Device Count

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. The module is ideal for areas where inputs and outputs are needed in the same location, such as smoke/fire dampers, HVAC fan, non-dedicated smoke fan, dedicated smoke control or 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, the surface-mounted SMB500 or into a DNR(W) duct housing.
