ESL Product Lines We Repair
Our engineers are trained on the full ESL product range. Below are the major product families we service.
ESL LED Emergency Luminaires
ESL's modular LED emergency lighting fixtures for maintained and non-maintained modes. Common faults include LED driver failure, battery contact corrosion, and photometric drift. Used in exits, corridors, and emergency routes across Indian manufacturing plants.
ESL Central Battery Systems
Intelligent, self-testing central emergency power backup systems for large industrial facilities. Faults typically involve NiCd or LiFePO4 battery degradation, charging circuit failure, and self-test module malfunction. Essential for Indian pharma, auto, and chemical plants.
ESL Self-Testing Control Modules
Autonomous test and monitoring units embedded in ESL luminaires and control panels. Common issues: battery voltage sensor drift, timer circuit failure, and relay stiction. Regularly serviced to maintain Fire Safety compliance in Indian industrial sites.
ESL Exit Sign Systems
High-brightness LED exit signage with integral or slave battery packs. Faults include LED module burnout, power supply regulation failure, and illumination inconsistency. Critical for escape route marking in Indian warehouses, hospitals, and factories.
ESL Maintained-Mode Luminaires
Always-on emergency lights for operational continuity in manufacturing floors and switching stations. Common faults: ballast capacitor aging, battery pack delamination, and photometric sensor contamination in dusty Indian plant environments.
ESL Photometric Regulators
Intelligent light-level sensors that adjust emergency luminaire output based on ambient lighting conditions. Faults include sensor photodiode drift, voltage regulator failure, and calibration loss. Essential for energy efficiency in 24/7 Indian manufacturing operations.

Common ESL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ESL equipment arriving at our workshop.
- ✓ESL LED Driver Failure - No Light Output — ESL LED emergency luminaires commonly suffer constant-current driver failure due to thermal stress in hot Indian factory environments (40-50°C ambient). Electrolytic capacitor degradation within 5-7 years is typical, causing intermittent or total LED outage.
- ✓Battery Contact Corrosion - Intermittent Operation — ESL battery compartments in maintained and non-maintained luminaires develop corrosion on contact pins due to humidity ingress in humid Indian coastal and monsoon regions. NiCd and sealed-lead-acid batteries release corrosive gases; stainless steel contacts still oxidise over 3-4 years.
- ✓Self-Test Module Failure - Continuous Cycling — ESL AutoTest and RemoteTest modules malfunction when internal timer capacitors age or temperature sensors drift. Indian plant dust and vibration accelerate relay contact wear, causing false self-test triggering or inability to complete test sequences per Fire Safety Rules 2019.
- ✓Battery Pack Delamination - Capacity Loss — ESL NiCd and sealed-lead-acid battery packs swell and delaminate in high-temperature zones (furnaces, boiler rooms) common in Indian steel, cement, and chemical plants. Electrolyte leakage damages PCB tracks and causes intermittent disconnects.
- ✓Photometric Sensor Drift - Inaccurate Light Adjustment — ESL photometric regulators accumulate dust and oil film on photodiode windows in dusty Indian manufacturing environments—textiles, grain processing, cement plants. This causes false ambient light readings, leading to over-bright or under-lit emergency routes.
- ✓Power Supply Regulation Failure - Unstable Output Voltage — ESL exit sign power supplies and luminaire regulators fail when voltage regulation transistors overheat or zener diodes shift. Industrial EMI from motors and switchgear in Indian plants induces transient spikes that degrade power components.

All LED luminaires, battery systems, and self-test modules are refurbished to original spec and re-certified with calibration data. We issue compliance documentation suitable for statutory fire safety audits and insurance inspections.
What is the typical lead time for ESL emergency lighting repair?+
Standard turnaround for ESL repairs is 5-7 working days from receipt. Critical/urgent repairs (LED driver replacement, battery reconditioning) are expedited within 48-72 hours. We provide temporary emergency lighting loaners for manufacturing facilities that cannot operate without 24/7 emergency egress illumination. Priority courier included for time-sensitive shipments.
Can Synchronics test ESL battery systems after repair?+
Yes. Synchronics performs full-load battery discharge testing, self-test cycle verification, and photometric output measurement on all ESL repairs. We use calibrated test equipment and document all results with serial numbers, batch codes, and repair signatures. Battery reconditioning protocols are specific to NiCd, sealed-lead-acid, and LiFePO4 chemistries used in ESL CBS systems.
Do you offer preventive maintenance contracts for ESL emergency lighting systems?+
Yes. Synchronics offers annual and bi-annual ESL maintenance contracts tailored to your facility type and environment—coastal, dusty, high-temperature, or vibration-prone zones. We conduct battery health testing, contact cleaning, photometric sensor calibration, and self-test verification. Documentation supports Fire Safety compliance audits.
How do I send my ESL unit for repair?+

What is the cost of repairing a ESL 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 ESL 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 ESL 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.
