LifeSafety Power F8P – Lock Wiring Guide
The F8P is an eight-output fuse-protected power distribution module, used with Alarm.com 4-door pre-wired kits (i.e., ADC-AC-LP1502-PSE and ADC-AC-x1100-4PSE). Each output is individually fused and features both power and fault LEDs for easy diagnostics. The F8P accepts voltages up to 28 VDC and is ideal for controlling magnetic locks, electric strikes, and related Access Control hardware.
Specifications
- Inputs:
- 12 VDC or 24 VDC nominal (20 A max per bus)
- Up to two power buses (B1 and B2) supported
- Outputs:
- 8 total zones, each selectable for B1 or B2 voltage, and FAI behavior
- Fused (3 A ATM style) or PTC (Class 2) protection per output
- Current:
- F8: 3 A max per output
- F8P: 2.5 A max per output (Class 2)
- Indicators:
- Bi-color LEDs for B1 and B2 bus power
- LED for FAI status input
System Wiring
1. Power Input Connections
- B1 Connectors (i.e., J1 and J4):
- Connect to primary power supply (DC positive, e.g., FPV4 DC out) for voltage bus B1.
- B2 Connectors (i.e., J3 and J5):
- Connect to secondary power supply (DC positive, e.g., B100 DC Out) for voltage bus B2 in dual voltage systems. Leave this disconnected in single voltage systems.
- BR Connectors (i.e., J3 and J6):
- Connect all BR (DC common) fastons system-wide for proper operation.
2. FlexIO Connectors
- Use either FlexIO connector for communication of FAI and Fault signals from an FPO supply and passing the FlexIO bus to additional accessory boards if needed.
Output Zone Wiring (Out1–Out8)
To use the F8P:
- Connect the lock
- While the system is powered down, connect +DC to the terminal marked c of the relay that the lock will be connected to.
- Connect the
of the lock to either NO or NC of the relay, depending on whether it is a fail-secure or fail-safe device. For more information see Access Control locking hardware wiring guide.
- Connect the
- Connect DC Ground of the lock to the terminal marked
.
Note: Verify input power matches the voltage rating of connected locks and system design.
- While the system is powered down, connect +DC to the terminal marked c of the relay that the lock will be connected to.
- Selecting the power selection setting per output:
- Each jumper on the output will govern how the power output operates. For example, a 24 VDC mag lock that needs to be disabled when the FAI is activated should be wired in to an output on the F8P that is set to position 3 in our ADC-AC-LP1502-PSE kits.

FAI (Fire Alarm Interface) Operation
- FAI status is received using the FlexIO connection from the FPO power supply.
- Each output can be configured to enable/disable based on the state of the FAI input, permitting system-wide power interruptions or lock releases required by code.
Note: Enables on FAI will only enable the output on the F8P when the FAI is activated. It is not suitable for fail secure locks. If a free ingress is needed for a fail secure lock, use the C4P or C8P.
