FRM501 Fire door control interface

Address-coded modules designed for various environments

◆ Product features

Low power consumption, bus system (alarm bus, power bus) has no polarity connection, and can regard as the same address code device to connect to the alarm bus, which is convenient for construction and flexible in use.
It can be used as the linkage control execution component of the controller and the controlled device, and can also receive the feedback signal of the controlled device after the action.
There are two fire door control interfaces, which can monitor two normally open fire doors, with functions of disconnection, short circuit fault monitoring for built-in external load.
