HES INC Product Lines We Repair
Our engineers are trained on the full HES INC product range. Below are the major product families we service.
HES 9600 Series Electric Strikes
Heavy-duty electromagnetic strike locks for institutional and industrial access control. Common failures include solenoid burnout from sustained voltage stress, armature plate misalignment, and power supply intermittency in humid Indian climates.
HES 5000 Series Mag Locks
High-holding-force electromagnetic locks used in secure entry points and server rooms. Typical issues include coil demagnetisation, thermal relay tripping, and mounting bracket stress fractures from vibration.
HES Power Supply Modules
Regulated 12V and 24V DC power supplies with battery backup for fail-safe locking systems. Repair needs include capacitor degradation, voltage regulation drift, and battery charger circuit failures.
HES Access Control Interface Cards
PCB-based relay and control modules integrating access credentials with electric lock actuation. Common faults include relay contact oxidation, firmware corruption, and 12/24V rail short circuits.
HES RCI Remote Control Interface
Standalone controllers for remote unlock and lock status monitoring. Typical failures involve network connectivity loss, RS-485 termination problems, and backup battery drainage.

Common HES INC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HES INC equipment arriving at our workshop.
- ✓Solenoid coil burnout in 9600 series strike — Continuous duty cycle activation or under-voltage condition starving the coil, causing excessive current draw and insulation breakdown. Common in Indian facilities with unstable power supply or improper voltage regulation.
- ✓Armature plate mechanical misalignment — Door frame settlement, improper installation depth, or corrosion of the strike mounting bracket causing the armature and coil to drift out of position. Rust is accelerated in coastal Indian regions.
- ✓Power supply regulation failure with voltage droop — Electrolytic capacitor failure or load dump events on industrial power circuits cause 12V/24V rail voltage to sag below 10.5V/20V minimum threshold, weakening solenoid activation.
- ✓Access control relay contact oxidation and dropout — High humidity, salt spray in coastal industrial areas, and arcing during high-current switching oxidise relay contacts, creating intermittent open circuits and failed unlock commands.
- ✓RS-485 communication loss between RCI and remote nodes — Cable shield degradation, unterminated twisted pairs, or EMI from nearby AC drives and motor circuits inject noise into the communication line, causing CRC errors and timeouts.
- ✓Battery backup circuit failure and loss of fail-safe power — Charger IC failure, shorted battery cell, or corroded battery connectors prevent charging and storage of emergency power. Backup door locks fail to operate during power outages affecting facility security.

Frequently Asked Questions — HES INC Repairs
Do you repair HES Inc. equipment anywhere in India?+
Yes. Synchronics repairs the full HES Inc. product range - electric strikes, mag locks, power supplies, access control interfaces, and RCI remote controllers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all other cities. Same facility in Vadodara, Gujarat. Turnaround time is typically 5-7 working days.
What HES Inc. products does Synchronics have expertise repairing?+
We specialise in repairing HES 9600 series electric strikes, 5000 series mag locks, power supply modules (9620/9625/9630), access control interface cards (RCI modules), and remote control units. Our engineers have certified training in HES solenoid diagnostics, PCB-level repairs, voltage regulation analysis, and electromagnetic force testing specific to HES equipment.
My HES electric strike won't energize when the access card is swiped. What could be wrong?+
Common causes include failed relay contacts in the interface card, voltage droop on the 24V power supply during coil activation, or a burned solenoid coil. Synchronics will test your power supply output under load, measure coil resistance, inspect relay contacts for oxidation, and identify communication failures between your card reader and lock controller. We repair or replace the faulty component and perform full functional testing.
Can you repair HES RCI (Remote Control Interface) units with communication errors?+
Yes. HES RCI units often suffer from RS-485 line termination issues, shorted data lines from EMI near motor drives, or corrupted firmware in network nodes. Synchronics performs RS-485 voltage and impedance testing, installs proper shielding and termination, and reflashes firmware if needed. We test multi-node networks to ensure reliable remote lock/unlock and status reporting.
What warranty and testing do you provide on repaired HES Inc. equipment?+
All HES repairs come with a 12-month parts and labour warranty. We perform end-of-line testing including voltage stability under peak load, solenoid pull-in force measurement, relay contact resistance verification, and full access control protocol testing. Every unit is test-cycled 50+ times before return to ensure reliability in your security system.
How do I send my HES INC unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a HES INC drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on HES INC repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your HES INC unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
