u Provides eight Form C relays
u 1 A at 5-24 VDC relay contact rating
u Allows remote control of outputs
The B308 Octo-output Module is suitable for
applications requiring Form C outputs to operate
auxiliary systems or to display fire system status at
remote annunciators. The B308 can interface with
building components such as HVAC, door lock
releases, and stairwell pressurization for complete
system control and monitoring.
Industrial, commercial, and institutional facilities are
typical installations for the B308 module. The eight on-
board outputs can be programmed to activate on
system alarm, system trouble, individual zone or point
faults, and through remote control by authorized
users.
System overview
The B308 Octo-output Module provides eight
programmable outputs. Each relay provides dry
contact switching rated for 1.0 A at 5-24 VDC. The
outputs are accessed through on-board screw terminal
connections.
The B308 is compatible with the SDI2 bus. The on-
board switches are used to specify module addresses.
Control panel programming will determine output
response to specific events.
The B308 receives serial data from the control panel
and activates outputs in response to control panel
conditions and settings. Outputs can be programmed
for remote control from a keypad.
Functions
Output Relays
Each output provides a normally-open and a normally-
closed output. Outputs can be configured in control
panel programming to indicate system events.
