Notice!
The control panel does not support multiple detectors in alarm. The control panel is
compatible with detectors with optional features. Do not mix detectors from different
manufacturers on the same circuit.
Notice!
UL 864
Fire and non-fire devices can share the expansion bus when the POPIT module provides data
isolation between the input and bus connections.
A fire test tests both the AC power and the battery.
Four-wire smoke detectors
When using four-wire smoke detectors, install a power supervision device according to the
manufacturer's instructions. You can connect any number of four-wire smoke detectors to the
control panel (subject to available auxiliary power).
The Reset Sensor command is available from the keypads when the Reset Sensor is enabled.
Connect the smoke detectors to a suitable interface such as the B208 Octo-input Module or
on-board point to meet UL and NFPA requirements.
Two-wire smoke detectors
Two-wire smoke detectors connect to the control panel only through the D125B Powered
Loop Interface. Two-wire detectors must be evaluated for electrical compatibility, and be UL
Listed for use with the control panel. Refer to the Dual Class B Initiating Module (D125B)
Installation Instructions for detectors UL Listed for compatibility and the maximum number of
detectors you can connect to each D125B loop.
You can also consult the smoke detector manufacturer to determine if a particular smoke
detector is UL Listed for use with the control panel. When enabled, the Reset Sensor
command is available from the keypads.
Compatibility specifications include:

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.

Other devices
Use a D130 Relay Module, D8129 OctoRelay, or Switched Aux (Terminal 8) to provide reset
capability to other initiating devices such as:

Voltage Range: 8.0 VDC to 14 VDC
UL Compatibility Identifier: Type A (for control panel, detector, and base)
Use a D125B Powered Loop Interface Module with two-wire initiating devices.
Use a D129 Dual Class "A" (NFPA Style D) Initiating Circuit Module with any type of
initiating device, except a two-wire smoke detector.
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.
