Unlocking on power loss or alarm trigger for emergency egress compliance. NFPA 101 and IBC-compliant for life-safety critical doors.

Fail-Secure Locks

Remain locked on power loss to maintain perimeter security during power events. Ideal for secure entries, server rooms, and restricted zones.

Monitored Door Hardware

Electric strikes and locks with integrated door position sensors, tamper detection, and relay feedback for real-time access event logging.

SDC Electric Locking Solutions

Industry-standard electric strikes and solenoid locks from SDC, engineered for ANSI/BHMA Grade 1 durability in institutional and commercial deployments.

What to Look For When Buying

The decisions that matter most before you spec.

Fail-Safe vs. Fail-Secure: Life Safety vs. Perimeter Security

Fail-safe locks unlock on power loss (required for emergency exits and panic hardware compliance), while fail-secure locks maintain lock status to prevent intrusion during outages. Choose fail-safe for public egress routes and fail-secure for server rooms, vaults, and restricted areas. Control systems integrate both types across a single deployment.

ANSI/BHMA Grade Ratings and Cycle Life Durability

Grade 1 strikes withstand 500,000+ cycles (heavy institutional traffic); Grade 2 handles 300,000+ cycles (mid-traffic commercial). Verify cycle rating against your facility's foot traffic and door-open frequency to avoid premature failure and access denial incidents.

Power Supply Consistency and System Redundancy

Electric strikes and solenoid locks demand stable 12/24V DC power with low ripple. Access hubs and controllers should include UPS-backed power distribution to prevent lock dropout during brownouts. Undersized power budgets cause system failures during critical security events.

Door Frame Material and Strike Compatibility

Aluminum frames, hollow metal doors, and glass-mounted applications require specific strike profiles and mounting depths. Verify frame thickness, latch bolt size, and reinforcement plate compatibility before purchasing to avoid field rework and installation delays.

Monitoring and Event Logging Integration

Monitored strikes with door position sensors and tamper alerts feed real-time events to access control systems for audit trails and security response. Non-monitored passive strikes offer no feedback, increasing blind spots in perimeter visibility and making threat detection reactive instead of preventive.

Local Code Compliance and Third-Party Certification

ANSI/BHMA, UL, and fire-rated certifications vary by jurisdiction and occupancy type. Healthcare, education, and government facilities often mandate specific grades and configurations. Confirm with local authority and consult our experts to avoid code violations and permit delays.

Technology Stack

The specs and acronyms that actually affect door locks & strikes performance.

Fail-Safe / Fail-Secure Operation

Fail-safe unlocks the door on power loss or alarm signal for life-safety egress; fail-secure remains locked to maintain perimeter security. Choose based on occupancy type (public vs. restricted) and local fire/building code requirements. Most deployments use hybrid approaches—fail-safe on main exits, fail-secure on utility areas.

Strike Voltage and Current Draw (12V/24V DC)

Electric strikes typically draw 200–600mA at 12V or 100–300mA at 24V during solenoid actuation. Higher voltage (24V) reduces I²R losses in long cable runs and is preferred for large facilities. Size power supplies and wiring gauge accordingly to prevent voltage sag under full load.

ANSI/BHMA Grade Ratings (1–3)

Grade 1 = 500,000+ cycles, heaviest duty; Grade 2 = 300,000+ cycles, medium commercial; Grade 3 = 100,000+ cycles, light residential. Grade 1 is standard for institutional and high-traffic security installations; lower grades risk premature failure and replacement costs.

Solenoid Latching vs. Momentary Activation

Momentary solenoids require continuous power to hold the lock open and release on de-energization; latching solenoids hold position after one pulse, reducing power consumption. Latching is preferred for battery-backed or remote installations to lower UPS/power-supply load.

Door Position Sensing and Tamper Feedback

Monitored strikes include magnetic reed switches or proximity sensors that signal door open/close state and contact tampering to the access control system. Non-monitored strikes are passive and provide no feedback, limiting audit visibility and threat detection responsiveness.

Reinforcement Plate Installation and Frame Compatibility

Strike plates must be secured to the door frame with through-bolts or wood screws through reinforcement plates to distribute load and prevent kick-in attacks. Aluminum frames and hollow-metal doors require specified plate thickness and bolt patterns; verify dimensions before procurement.

Typical Deployment Scenarios

Mid-Sized Office Building Perimeter (12 Ground-Floor Entries)

Deploy 12 fail-secure SDC electric strikes on main lobbies, server room, and secure offices. Back with a 24V/5A distributed power supply and a door controller managing unlock schedules and monitoring door-position sensors for intrusion alerts. Integrate card readers at each strike for access logging.

Hospital Emergency Department (8 Fail-Safe + 4 Fail-Secure Mixed)

Public egress areas (ER waiting, hallways) use fail-safe strikes for panic compliance; restricted zones (pharmacy, med storage, ICU) use fail-secure. All 12 strikes feed unified control system with UPS-backed power and monitoring. Solenoid latching reduces power draw on battery backup.

School Campus Corridor Lockdown (20 Classrooms + 4 Emergency Exits)

Install fail-secure electromechanical locks on 20 classroom doors with manual override capability; 4 main exits use fail-safe strikes for evacuation. Access hub centralizes release during threat events. See school security design guide for integrated lockdown workflows.

Data Center Secure Entry (6 Cage Doors + Server Room Access)

Six fail-secure solenoid-latching locks on equipment cages and server room doors minimize UPS drain. Monitored strike sensors log every open event for compliance audits. Pair with proximity card readers for multi-factor credential checks and integrate door I/O modules for alarm feedback.

Frequently Asked Questions

What's the difference between a fail-safe and fail-secure electric strike?

Fail-safe strikes unlock when power is lost or an alarm is triggered—critical for emergency exits and life-safety compliance. Fail-secure strikes remain locked on power loss to prevent intrusion. Building code and occupancy type determine which you need; most facilities use both: fail-safe on public exits, fail-secure on secure entries and restricted zones.

How do I choose between 12V and 24V electric strikes?

24V systems are preferred for large deployments because they reduce current draw (lower I²R losses), cause less voltage sag in long cable runs, and are safer for wet environments. 12V is acceptable for small, localized installations near the power supply. Always verify your access control panel's output voltage and power budget before selecting strikes.

What ANSI/BHMA grade should I specify for a commercial deployment?

Grade 1 (500,000+ cycles) is industry standard for institutional, government, and high-traffic commercial facilities. Grade 2 (300,000+ cycles) suits mid-traffic office buildings. Grade 3 is rarely used in professional security contexts. Higher grade ensures durability and reduces warranty/replacement risk over a 10+ year lifecycle.

Do I need monitored strikes or can I use passive non-monitored locks?

Monitored strikes with door-position sensors provide real-time open/close events and tamper alerts for audit trails and threat detection. Non-monitored strikes offer no feedback and create blind spots in your access control visibility. For compliance-heavy environments (healthcare, finance, schools), monitored hardware is strongly recommended.

How much power do electric strikes consume, and will my UPS back them up?

Most strikes draw 200–600mA at 12V (2.4–7.2W) or 100–300mA at 24V (2.4–7.2W) during solenoid actuation. Latching solenoids hold position after one pulse and consume less continuous power. Estimate total door count × latching solenoid wattage, add margin, and select a UPS rated for sustained hold-time during outages. Undersized UPS causes lock dropout during power events.

What's the installation process, and do I need a professional integrator?

Strike installation involves mounting the strike plate and reinforcement bracket to the door frame using through-bolts or wood screws, ensuring proper alignment with the latch bolt and frame material. Wiring requires low-voltage DC runs from the power supply and control panel with proper shielding for noise immunity. Professional installation is recommended to avoid frame damage, improper strike orientation, and code violations. Contact our experts for site assessment and integration guidance.
