Intruder alarm servicing keeps your alarm system reliable long after installation. Over time, backup batteries lose capacity, detectors collect dust, and sirens weaken. Consequently, a system that once responded instantly may fail silently when you need it most. Scheduled intruder alarm servicing catches these faults early and restores the system to full working order.
Proftech provides professional intruder alarm servicing across Nairobi and the wider Kenyan market. Our technicians service residential alarms, commercial systems, and wireless panic setups. Furthermore, we work across the major brands sold in Kenya, including Paradox, DSC, Texecom, IDS, and Sherlotronics.
What a Full Service Visit Covers
Each intruder alarm servicing visit follows a structured checklist. As a result, no component is overlooked.
- Control panel inspection — we check wiring terminations, zone configurations, and event logs for recurring faults or tamper alerts.
- Backup battery testing — standby batteries are load-tested and replaced when capacity drops, since most alarm batteries degrade within 2–4 years in Kenyan heat.
- Detector cleaning and walk-testing — PIR and dual-tech sensors are cleaned, realigned, and walk-tested to confirm full coverage with no blind spots.
- Siren and strobe testing — internal and external sounders are activated to verify audible output and strobe operation.
- Panic button verification — fixed and wireless panic buttons are triggered and traced through to the panel or monitoring base.
- Communicator testing — GSM and IP communicators are tested end-to-end, so signals actually reach your phone or monitoring company over Safaricom or Airtel.
Why Regular Servicing Matters
An unserviced alarm creates false confidence. For example, a flat standby battery means the system dies during a blackout — precisely when intrusion risk is highest. Similarly, a dusty PIR sensor may trigger false alarms, and repeated false alarms lead guards and neighbours to ignore genuine activations.
Regular intruder alarm servicing also protects your investment. Insurers increasingly ask for proof of alarm maintenance when processing burglary claims. Therefore, a documented service record supports both your security and your paperwork.
Fault Repairs and System Upgrades
Servicing visits frequently reveal upgrade opportunities. Where needed, we repair or replace faulty zones, extend coverage with additional detectors, and add GSM communicators to older dialler-based panels. In addition, we integrate intruder alarms with electric fence energizers, CCTV systems, and wireless panic bases such as the Sherlotronics MB4000 for estate-wide monitoring.
Service Plans and Response
Proftech offers one-off service visits and scheduled maintenance contracts. Contract clients receive priority fault response, discounted spares, and a documented service history for each site. Moreover, multi-site businesses can consolidate all their branches under a single servicing agreement with unified reporting.
Who Is This Best Suited For
- Homeowners with aging alarm systems — backup batteries typically degrade within 2–4 years, so any system older than that benefits from immediate battery testing and replacement.
- Businesses and retail premises — walk-testing every PIR and dual-tech detector confirms full zone coverage after shop refits, shelving changes, or office reorganisations.
- Gated estates and residential communities — panic button verification and communicator testing keep estate-wide response systems dependable across dozens of households.
- Landlords and property managers — documented service records across multiple properties support insurance requirements and tenant safety obligations.
- Companies with monitored alarms — end-to-end GSM and IP signal testing confirms activations actually reach the monitoring centre, not just the local siren.
- Sites with frequent false alarms — detector cleaning, realignment, and zone diagnostics remove the most common causes of nuisance triggering.
