Core Responsibilities

Primary Functions

Install, mount, wire and terminate intrusion alarm control panels, sensors, contacts, motion detectors, glass-break detectors and keypads to manufacturer specifications and site plans, ensuring compliance with local codes and customer requirements.
Program alarm panels, user codes, zones, partitions and reporting formats (including IP/GSM/Cellular/Phone line communicators) using manufacturer software (e.g., Honeywell, DSC, DMP, Bosch, UTC, Siemens) and ensure successful connection to central monitoring stations.
Install, configure and commission IP and analog CCTV systems, including PoE switches, NVR/DVR units, camera alignment, lens setup, exposure, PTZ presets, and ensure proper recording and remote viewing.
Troubleshoot and repair failed alarm sensors, control panels, communication modules, power supplies, batteries and wiring faults using multimeters, cable testers and diagnostic software; isolate and remediate intermittent faults under time constraints.
Diagnose and service access control systems—controllers, readers, maglocks, electric strikes, door position switches and elevator interfaces—programming credentials, access levels and schedules.
Perform comprehensive on-site and remote system commissioning: verify inputs/outputs, walk-test intrusion and fire devices, test notification appliances, and document results with test logs and as-built diagrams.
Perform periodic preventive maintenance contracts, update firmware and software, replace batteries and consumables, and provide customers with detailed service reports and recommended corrective actions.
Conduct fire alarm testing and inspection per NFPA and local authority having jurisdiction (AHJ) requirements, test notification circuits, supervision circuits and initiate AHJ-required documentation and reporting.
Read and interpret blueprints, riser diagrams, electrical schematics and site plans to determine routing, mounting locations and equipment placement; coordinate conduit and low-voltage pathways with general contractors and electricians.
Run, terminate and test structured cabling (Cat5e/Cat6) for IP devices, label cabling and update network diagrams; troubleshoot IP connectivity, switch configuration, VLANs and PoE issues in coordination with IT teams.
Execute pre-installation site surveys including power availability, network readiness, mounting locations, camera coverage analysis and customer expectations, then recommend equipment and system design changes.
Integrate third‑party systems and devices (intercoms, building management systems, video analytics, alarm monitoring platforms) and validate end‑to‑end alarm reporting and automation workflows.
Maintain company fleet, tools and inventory; ensure equipment is calibrated, charged and stocked for field jobs and complete accurate parts usage and time reporting in the field service management system.
Respond to service calls and emergency alarms with urgency during on-call rotation; perform remote diagnostics to reduce truck rolls and escalate complex issues to engineering or project management as needed.
Provide clear, professional customer communication including onsite walkthroughs, operator training, and explanation of system operation, maintenance needs and warranty coverage.
Complete service paperwork, change orders, site-specific safety plans, permit documentation and as-built drawings; update the CRM and job management systems with accurate status and billing details.
Follow confined space, ladder, fall protection and facility-specific safety procedures; wear PPE and maintain a tidy, professional appearance when working in customer environments.
Conduct post-installation verification and customer acceptance testing; obtain customer sign-off and provide printed or digital operation guides and credential handover.
Support commissioning and turnover processes for large commercial projects including punch-list resolution, coordination of multi-trade scopes and final system acceptance with general contractors and owners.
Mentor and train junior technicians and apprentices on installation best practices, manufacturer programming and field safety protocols; contribute to job shadowing and skills development programs.
Keep current on manufacturer product updates, firmware releases and industry best practices; perform on-the-job evaluation of new hardware and recommend upgrades to the product portfolio.
Manage vendor RMA processes and warranty claims for defective components; coordinate repairs or replacements with distribution partners and manufacturers.
Ensure compliance with licensing requirements, municipal permits and industry codes (NFPA, UL, local AHJs); prepare documentation for inspections and support code inspection visits.
Conduct capacity planning for service calls and assist dispatch in optimizing routes, estimating time-on-site and prioritizing emergency repairs or high-value accounts.

Secondary Functions

Support sales and project teams by providing technical takeoffs, labor estimates, and site feasibility feedback for proposals and change orders.
Assist in the development and maintenance of standard operating procedures (SOPs), installation guides and troubleshooting playbooks to increase field consistency and first‑time fix rates.
Participate in continuous improvement initiatives: capture recurring fault data, recommend design or product changes, and help reduce mean time to repair (MTTR).
Provide subject-matter expertise for remote diagnostic tools and support the implementation of remote monitoring platforms for proactive maintenance.
Coordinate equipment procurement, manage short-term rental equipment needs, and track warranty periods and serial numbers in asset databases.
Attend weekly operations and safety meetings; contribute field insight to improve scheduling, parts stocking and customer communications.
Assist with occasional after-hours emergency response and participate in the on-call rotation to ensure 24/7 coverage for critical alarm events.
Support training sessions for customers and internal teams on system features, mobile app usage, alarm response protocols and basic troubleshooting.
Help maintain digital as-built documentation, device lists, IP address inventories and network diagrams to streamline future service calls.
Aid in quality assurance and final inspection processes for completed projects to ensure installations meet company standards and contractual obligations.
