NFPA Style A (Class “B”) Circuit
Loops A and B on the D125B Module are NFPA Style A (Class “B”) initiating circuits suitable
for connecting any fire alarm initiating device, including two-wire and four-wire smoke
detectors.
Connecting initiating devices to on-board points (1 through 8) on the control panel:
– Use a D125B Powered Loop Interface Module with two-wire initiating devices.

initiating device, except a two-wire smoke detector.
Connecting initiating devices to off-board points:
– Do not connect two-wire smoke detectors to POPITs or MUX bus inputs.
– Use the D9127U or D9127T POPIT Modules to connect four-wire smoke.
Other devices
Use a D130 Relay Module, D8129 OctoRelay, or Switched Aux (Terminal 8) to provide reset
capability to other initiating devices such as:
– B308 Octo-output Module
– D125B Powered Loop Interface Module (2-wire smoke detector module)
– D129 Dual “Class A” Initiation Circuit Module (4-wire smoke detector)
– D9127T/U POPITs
