HES 2005M3 SMART Pac III — In-Line Power Controller for Electric Strikes

The HES 2005M3 SMART Pac III is a purpose-built, in-line power controller designed to optimize and protect HES electric strikes in commercial access control installations. By conditioning input power, reducing inrush voltage, and providing built-in surge protection, the 2005M3 extends strike service life and — critically — doubles the HES electric strike warranty from the standard 1-year electrical coverage to the full 3–5 year mechanical warranty term applicable to each HES series.

For security integrators, electrical contractors, and facility managers specifying or servicing electrified door hardware, the SMART Pac III is a low-cost accessory that delivers measurable protection for the strike investment on every opening.

Key Benefits

• Wide input voltage range (12–32V AC or DC): Eliminates the need for voltage-specific pigtails — one controller works across a broad range of power supply outputs, simplifying specification and stocking.
• Continuous duty voltage reduction: After an initial energization period, the controller automatically reduces output voltage by 25%, lowering heat buildup in the strike solenoid and extending service life in high-cycle applications.
• Built-in bridge rectifier: Accepts AC or DC input and delivers clean DC output — no separate rectifier required. Output is 12VDC or 24VDC depending on input voltage.
• Built-in MOV surge protection and voltage regulation: Shields the electric strike from voltage spikes and power irregularities that commonly damage solenoid components.
• Self-resetting over-current protection (resettable fuse): Automatically recovers from overcurrent events without requiring fuse replacement — reduces service calls and downtime.
• Smart LED input status indicator: Provides at-a-glance confirmation of power input status during installation and troubleshooting.
• Supports fail-secure and fail-safe electric strike configurations: Compatible with both strike types across HES product lines.
• Warranty extension: Installing the 2005M3 with any new HES electric strike extends the 1-year electrical component warranty to match the full mechanical warranty term (3–5 years by series).

Typical Applications

• New HES electric strike installations requiring power conditioning (1006, 1500, 1600, 4500, 5000, 5200, 5300, 8000, and 9000 series)
• Retrofit installations where existing power supplies deliver AC voltage that must be converted to DC for strike operation
• High-traffic commercial doors where continuous-duty solenoid operation creates heat-related wear
• Any access-controlled opening where extended strike warranty coverage is desired

Installation Notes

The 2005M3 installs in-line between the power supply and the electric strike — no special tools or frame modifications required. It is compatible with both fail-secure (power = unlocked) and fail-safe (power = locked) configured HES strikes. Note that the SMART Pac III cannot boost output voltage above the input voltage level — verify the power supply output meets or exceeds the strike's operating voltage requirement before specifying a lower-input scenario.
