Eaton Auxiliary Relay Output Daughter Board for Use with FPE, FRE BWOB8Z

Eaton BWOB8Z Auxiliary Relay Output Daughter Board provides additional relay outputs to fire protection equipment (FPE) and fire alarm routing equipment (FRE) systems. Designed to enhance fire detection and control system capabilities, this daughter board offers 8 auxiliary relays that are volt free and single pole double throw, ensuring safe operation without supplying voltage through relay contacts.

The FRE output is specifically designed to activate during fire events and can be connected to phone dialers or building management systems, complying with EN54-2 standards to meet fire safety regulations and system interoperability requirements.

The FPE output can activate external devices such as door release mechanisms, fire screens, sprinkler systems, and gas release systems during fire situations, providing essential control functionality within complex fire protection setups.

The relays on the board are selectable as common/normal open or common/normal closed contacts, providing flexibility in installation and system design. Zone relay contacts are designed to follow the fire condition status of the associated zone circuits from the main control board, allowing for precise control and indication of protected zones.

Operating within an 18.75 to 30.7 V voltage range, this daughter board supports reliable and safe operation in fire alarm and protection systems used in commercial, industrial, and institutional buildings.

Manufactured in the United Kingdom, the Eaton BWOB8Z unit exemplifies quality and compliance with fire safety product standards. The daughter board provides 8 auxiliary volt-free, single pole double throw relays. Relays are selectable as common/normally open or common/normally closed contacts.

FRE output activates during fire events and interconnects with phone dialers and building management systems. FPE output drives door releases, fire screens, sprinklers, and gas release systems. Zone relays track fire conditions of associated zones accurately.

Operating voltage range of 18.75 to 30.7 V ensures compatibility. Volt-free relay contacts provide safe isolation. Designed for integration in fire alarm routing and protection equipment. Manufactured in the United Kingdom with EN54-2 compliance.
