Lifesafety Power M8P-BOXED 8-Output Managed Control Module
The Lifesafety Power M8P-BOXED is a networked power distribution and control module designed for access control, emergency egress, and critical-circuit management in mid-to-large deployments. It delivers eight independently monitored and controlled voltage outputs, dual-voltage capability (12V / 24V), and network-programmable failsafe/failsecure logic—eliminating manual relay configuration and reducing on-site engineering. Integration with NL4 or NLX network modules enables centralized control and real-time monitoring across distributed sites, accessible from on-premises NVR interfaces or internet-connected management platforms.
Key Features
- Eight Monitored Outputs: Individual voltage and current monitoring on each output with user-defined alert thresholds. Detect over-current faults, open circuits, and load anomalies in real time.
- Dual-Voltage Support: Selectable 12V or 24V per output in multi-voltage iSCAN power systems. OutSmart dual-color LEDs (green for 12V, blue for 24V) provide at-a-glance status confirmation.
- Eight Control Inputs: Voltage or dry-contact activation inputs for remote triggers, emergency panels, or manual override circuits without network dependencies.
- Network Programmable Failsafe/Failsecure Logic: Per-output configuration for access-controlled locks, emergency egress, and fire alarm override—no jumper installation required. AC loss override for life-safety compliance.
- One Dry Relay Output: Selectable relay output for signaling external devices, horn controllers, or notification systems independent of voltage supply rails.
- RS-485 Optional Integration: Remote monitoring via NLX using RSMOD module (sold separately) for extended-distance telemetry and redundant communication paths.
- Browser-Based Management: Individual output enable/disable, voltage/current trending, and alert configuration through standard web interface—no proprietary software required.
- Compact Modular Form Factor: Stackable design for scaling across multi-zone facilities; integrates directly into iSCAN power enclosures.
The M8P-BOXED simplifies distributed power management by eliminating mechanical relays and hardwired failsafe logic. Each output is independently programmable for its intended load profile and override behavior, reducing system commissioning time and post-installation change orders. Integrators appreciate the flexibility: a single M8P can handle door locks on multiple zones, each with independent failsafe characteristics, all managed from a centralized interface. Current monitoring also serves a diagnostic function—rising current draw on a lock output often signals mechanical wear or jammed hardware, enabling predictive maintenance before field callouts.
The dual-voltage capability addresses mixed-load environments common in enterprise facilities. 12V locks, 24V mag-locks, and 24V solenoid gates can all operate from the same power distribution module without external buck converters or separate control branches. Pair the M8P with an NL4 module for standalone operation (single-site) or an NLX for network-distributed control across campuses or multi-tenant buildings. Fire alarm integration is native—a two-wire input from the fire panel can override all locks simultaneously, with output-specific override policies preventing unintended door releases during false alarms.
The M8P-BOXED operates within Lifesafety Power's iSCAN ecosystem, which prioritizes redundancy and fail-safe operation. Unlike generic industrial power distribution modules, every output defaults to a safe state on power loss, network loss, or device reset—critical for life-safety applications. The browser-based monitoring interface integrates with existing facility management tools via ONVIF-compatible network messaging; API webhooks can trigger third-party alerting (email, SMS, Slack) when output anomalies occur. Typical deployments span 4-16 modules per facility, depending on zone count and functional separation (e.g., separate power trees for egress locks vs. access-controlled gates).

The M8P-BOXED occupies a unique niche in the access control power landscape: it's neither a simple relay module nor an enterprise-scale UPS system, but rather a intelligent, networked load controller that bridges facility-wide power management with per-output failsafe logic. In our experience deploying these across office parks, universities, and mixed-use facilities, the M8P shines when you have 4-12 independently controlled circuits that need both remote visibility and bulletproof failsafe behavior on power loss or network interruption. The programmable relay output is underutilized in many installations—we've successfully used it to signal external solenoids, audible warnings, and even parking-gate drop bars that operate outside the main voltage distribution rail.
Where the M8P differs from competitive offerings (Eaton, Lowell, generic industrial DIN-rail modules) is integration tightness with access control logic. Unlike a dumb power supply with hardwired relay sequencing, the M8P allows you to change failsafe policy, override priority, and AC loss behavior without re-wiring or manually adjusting relays. We've retrofitted aging facilities where the original design called for four separate power supplies with mechanical priority relays—replacing that tangle with two M8P modules and a single larger supply cut installation time and warranty support overhead significantly.
Technical Highlights:
- Dual-Voltage Flexibility (12V / 24V per output): In practice, this eliminates the need for separate supply rails or DC-to-DC converters on mixed loads. A single M8P can handle 12V locks and 24V solenoids from one AC input, simplifying UPS integration and reducing total system capex by consolidating smaller PSUs into a single larger unit.
- Per-Output Current Monitoring with Configurable Thresholds: We've used this feature to detect stuck solenoids, short circuits on cable runs, and mechanical lock failures within minutes of onset. Alerting on 500mA over-current on a 12V lock output is often the first sign of a jammed mechanism—address it before the lock fails to open during an emergency.
- Programmable Failsafe / Failsecure Override Hierarchy: The ability to set fire alarm override on door locks while excluding gate solenoids from the same override signal prevents unintended release of perimeter gates during fire events. Life-safety code compliance without custom engineered interlocks.
- Eight Dry-Contact Inputs: Beyond simple on/off signals, these can be wired to legacy access control panels, motion sensors, or manual pushbuttons. A two-conductor run from a remote panic button to one input costs $50 in wire versus a dedicated hardwired relay circuit.
- Browser-Based Trending and Diagnostics: Voltage sag under load, intermittent current spikes, and supply stability can be monitored passively without specialized test equipment. Many field engineers keep the M8P admin page open during first power-up to verify load sequencing is correct.
Deployment Considerations:
- RS-485 remote monitoring via RSMOD is optional but highly recommended for multi-site deployments. Without it, you lose real-time alerting unless the M8P is on the same Ethernet network as your NVR. Budget an extra RSMOD module for any facility spanning multiple buildings or floors.
- Each M8P must be paired with either an NL4 (single-site, no network redundancy) or NLX module (networked, with failover capability). Confirm module type during procurement; they're not interchangeable and installation errors cause dead outputs on startup.
- Voltage drop over long cable runs to remote locks can cause the M8P to fall outside its regulation window (typically ±10% of nominal). For runs exceeding 150 feet, verify loop resistance and wire gauge with Lifesafety Power's sizing tool—undersized cable is a common commissioning surprise.
- The dual-color LED indicator is useful for on-site troubleshooting but relies on line-of-sight visibility. In wall-mounted or cabinet-mounted installations, consider adding an external status lamp or routing a network alert to a NOC display for 24/7 awareness.
- Failsafe behavior on AC power loss is non-negotiable for egress locks (code requirement), but must be explicitly set per output during commissioning. Default-shipped configurations often lock all outputs—verify each one matches your egress policy before going live.
The M8P-BOXED is the right fit for integrators managing mid-scale access control retrofits, campus-wide lock upgrades, and any project where remote failsafe control and per-output diagnostics justify a networked power module over cheaper alternatives.
