S4 Interface Modules

S4 Interface Modules input/output interface module can be configured to provide any combination of up to four inputs or outputs. An output of either normally open or normally closed relay contacts can be used to control a load of up to 1A @ 30V DC/ac .

Each module includes a loop isolator for device isolation. Each interface module use one of 207 available device addresses on a loop and responds to regular polls from the control panel reporting the type of device and the status

The S4 interface modules can be mounted in other equipment housings using the DIN rail mount brackets can also be fitted into a plastic box

An input can be programmed as a fire, fault, supervisory or confirmation input. Additionally it is possible for channel 1 to be used as a Zone input, which allow connection of conventional detectors and MCPs to this module. Zone input can be configured to have alarm validation feature and configurable reset time
