Electric Strikes vs Electromagnetic Locks: Choosing the Right FSH Solution
FSH produces three primary categories of electronic locking hardware: electric strikes, electric mortice locks, and mechanical electromagnetic locks. Understanding the difference is essential for correct specification.
Electric strikes replace the fixed strike plate in a door frame, allowing the latch or bolt of a standard mechanical lock to release electronically. They are ideal for doors that already have a mortice lock fitted, and they preserve the mechanical lock as a backup. FSH electric strikes are available in ANSI footprint and high-security configurations, with monitored variants providing real-time feedback on latch engagement, locking mechanism status, and tamper detection.
Electric mortice locks integrate the electronic locking mechanism directly into the lock body, replacing the mechanical mortice lock entirely. The FSH FEL990M is non-handed, fire rated, and supports both vestibule and combination locking modes - making it a clean, integrated solution for new installations where a separate strike and lock combination is not preferred.
Mechanical electromagnetic locks (maglocks) hold the door closed using magnetic force between a lock body and an armature plate. FSH's MEM2400 series is 70-75% smaller than a traditional maglock while delivering up to 1,000kg of holding force - making them suitable for glass doors, narrow frames, and installations where space is constrained.
---FSH Electric Strike Range
FSHFES10 - ANSI Footprint Electric Strike (Non-Monitored, IP56)
The FSHFES10 is a mortice-mount electric strike designed for standard ANSI footprint applications. It supports field-selectable fail-safe (PTL) or fail-secure (PTO) operation and is rated IP56, making it suitable for weather-exposed areas such as external gates and covered entry points. Operating at 12/24VDC with a current draw of 200mA at 12VDC, it is a reliable and cost-effective choice for non-monitored installations.
---FSHFES10M - ANSI Footprint Electric Strike (Monitored)
The FSHFES10M shares the same ANSI footprint and field-selectable fail-safe/fail-secure operation as the FES10, but adds door latch sensor (DSS) monitoring. The DSS confirms that the door latch is engaged within the strike keeper - providing the access control system with real-time door status feedback. This is the preferred choice for monitored access control panels where door state verification is required.
---FES20M - High Security Electric Strike (Monitored)
The FES20M is FSH's high-security monitored electric strike, designed for demanding commercial and institutional applications. It operates across a wide multi-voltage range of 12-36VDC at 220mA, and provides three independent monitoring outputs:
- LSS (Latch Status Sensor) - monitors the status of the internal locking mechanism
- DSS (Door Status Sensor) - confirms the door latch is engaged within the strike keeper
- ATS (Anti-Tamper Switch) - detects if the strike is being removed from the frame
The triple-monitoring capability makes the FES20M the preferred specification for high-security doors, server rooms, and any application where tamper detection is a requirement.
---FES90M-P - High Security Electric Strike with Preload Capability
The FES90M-P is FSH's most advanced electric strike, engineered for doors subject to wind load, pressure differentials, or heavy use. Its 35kg preload capability actively holds the latch in the strike keeper during the locking and unlocking cycle, preventing the latch from being pushed back by door pressure. This eliminates the common failure mode where a door under load prevents the strike from releasing cleanly.
The FES90M-P operates in two modes to minimise power consumption:
- Active Mode: 300mA at 12VDC - only during locking and unlocking action
- Sleep Mode: 15mA at 12VDC - in locked or unlocked state
Monitoring includes LSS (internal locking mechanism status) and DSS (door latch engagement). Operating range is 10-30VDC, making it compatible with a wide range of access control power supplies.
---FSH Electric Mortice Lock
FEL990M - FSH Electric Mortice Lock (Monitored)
The FEL990M is FSH's monitored electric mortice lock, designed for doors where a fully integrated locking solution is preferred over a separate electric strike and mechanical lock combination. It is non-handed and field selectable for left or right hand operation, and supports both vestibule (single-sided) and combination (double-sided) locking modes - selectable in the field without tools.
The FEL990M operates at 12-24VDC with a momentary current draw of 350mA and a holding current of 100mA, making it efficient for battery-backed access control systems. It is fire rated and requires no cylinder, integrating directly with Legge 700 Series LED furniture for status indication at the door.
Monitoring outputs cover the full lock state:
- Locking bar status - confirms hub/handle(s) are locked
- Deadlatching bolt - confirms bolt is depressed
- Latchbolt status - confirms latch is extended
- Door position - monitored via reed switch
- Dual Key Override Monitoring (KOM) - detects when a mechanical key override is used
- Request to Exit (REX) - triggered via hub/handle(s)
The FEL990M is available in four backset options to suit standard and non-standard door preparations:
- 60mm backset (SKU: FEL990M)
- 70mm backset (SKU: FEL990M70)
- 89mm backset (SKU: FEL990M89)
- 127mm backset (SKU: FEL990M127)
FSH-MTKIT - FSM Mortice Lock Kit
The FSH-MTKIT bundles the FEL990M electric mortice lock with a 300mm power transfer lead cover (IRT881SSS) - providing everything needed for a complete mortice lock installation in a single kit. The lead cover manages the wiring transition between the door frame and the door leaf, protecting the cable from wear over the door's operating cycle. This kit is suitable for doors that open to a maximum of 120 degrees.
---FSH Mechanical Electromagnetic Lock Range
The FSH MEM2400 series redefines what a maglock can be. At 70-75% smaller than a traditional electromagnetic lock, these units deliver up to 1,000kg of holding force in a compact, anti-tamper bracket assembly - suitable for glass doors, narrow aluminium frames, and installations where a standard maglock body would not fit.
---FSHMEM2400LP - Mechanical Electromagnetic Lock (Outward Opening Doors)
The FSHMEM2400LP is designed for outward-opening doors and includes a light panel indicator. It operates at 12/24VDC with a current draw of 240mA at 12VDC, and features three monitoring outputs:
- LSS (Hall Effect Sensor) - detects the magnetic field to confirm lock engagement
- DSS (Door Status Sensor) - detects the armature plate magnet via reed switch
- EW (Early Warning) - alerts if attempts are made to open the door while locked
The anti-tamper bracket is included as standard, and the compact form factor makes this unit suitable for glass door installations and narrow frame profiles.
---FSHMEM2400LED-LZ - Mechanical Electromagnetic Lock (Inward Opening Doors)
The FSHMEM2400LED-LZ is the inward-opening door variant of the MEM2400 series. It operates at 12/24VDC with a current draw of 350mA at 12VDC and includes L and Z brackets as standard - eliminating the need to source mounting hardware separately. Monitoring outputs are identical to the LP variant: LSS Hall Effect Sensor, DSS Door Status Sensor, and EW Early Warning alarm.

---Monitoring Outputs Explained
FSH's monitored electronic locks use a consistent set of monitoring output codes across the range. Understanding these is important when integrating with an access control panel:
- DSS (Door Status Sensor / Door Latch Sensor) - confirms the door latch or armature plate is in the correct position. This is the most common monitoring output and is present on all monitored FSH locks.
- LSS (Latch Status Sensor / Hall Effect Sensor) - monitors the internal locking mechanism or magnetic field. Present on the FES20M, FES90M-P, FEL990M, and both MEM2400 variants.
- ATS (Anti-Tamper Switch) - unique to the FES20M, this output triggers if the strike body is removed from the door frame.
- EW (Early Warning) - unique to the MEM2400 series, this output alerts the access control system if force is applied to the door while it is locked.
- KOM (Key Override Monitoring) - unique to the FEL990M, this output detects when a mechanical key override has been used to operate the lock.
When specifying a monitored lock, confirm which monitoring outputs your access control panel supports. Most commercial panels support DSS as a minimum; high-security panels will support LSS and ATS inputs as well.
---Fail-Safe vs Fail-Secure: Which Mode Should You Select?
All FSH electric strikes and the FEL990M electric mortice lock support field-selectable fail-safe (PTL - Power to Lock) or fail-secure (PTO - Power to Open) operation. The correct selection depends on the door's function and the applicable building code requirements.
Fail-safe (PTL) means the lock releases when power is lost. This is required on fire egress doors and any door that must allow free exit in an emergency. Most access-controlled entry doors in commercial buildings are specified fail-safe.
Fail-secure (PTO) means the lock remains locked when power is lost. This is appropriate for high-security doors such as server rooms, vaults, or areas where unauthorised access during a power outage would be a greater risk than restricted egress.
For guidance on fail-safe and fail-secure requirements under New Zealand building regulations, refer to the New Zealand Building Code Clause C6 (Fire Safety Systems) and consult a licensed building practitioner or fire engineer for site-specific advice.
