Install and program access control hardware including card readers, strikes, maglocks, controllers, and proximity/Bluetooth credentials and integrate with intrusion/fire systems as required.
Perform site surveys and read blueprints, riser diagrams and floor plans to develop cable runs, power requirements, and system placement recommendations; provide accurate time and materials estimates to project managers.
Test, troubleshoot and repair system faults using diagnostic tools (multimeter, cable tester, tone generator, network tester) to isolate wiring, power, communication and device failures; escalate complex faults to engineering as needed.
Conduct acceptance testing and final walkthroughs with customers, validate system functionality, document test results, obtain sign-offs, and provide clear instructions for use and alarm response procedures.
Execute preventive maintenance agreements including scheduled inspections, battery load tests, firmware updates, sensor cleaning, padlock and hardware checks, and maintain maintenance logs and service reports in the company’s ticketing system.
Ensure all installations meet local codes and standards and coordinate required permits and inspections with AHJ (Authority Having Jurisdiction); correct code violations and provide documentation for final approvals.
Troubleshoot IP network-related issues affecting alarm and video systems; configure static IPs, DHCP reservations, port forwarding, VLANs, and work with customer IT teams to resolve connectivity and bandwidth problems.
Maintain accurate, professional field documentation: completion reports, punch lists, As-Built drawings, cabling maps, and time/expense records using mobile devices and the company’s workflow tools.
Install and wire auxiliary devices and system expansions such as environmental sensors, panic buttons, intercoms, emergency power systems, and remote annunciators as part of integrated security solutions.
Respond to emergency service calls and alarms after hours on a rotating on-call schedule; perform rapid diagnostics, temporary remediation, and schedule follow-up repairs to minimize downtime for customers.
Train end-users and facility staff on system operation, user programming, arming/disarming, alarm verification, and basic troubleshooting; supply user guides and recommend best practices for security and life-safety.
Coordinate with electricians, general contractors and other trades on project sites to ensure proper power provisioning, conduit routing and mechanical support for security equipment installations.
Maintain vehicle and stocked inventory of installation materials, spare parts, documentation and tools; perform regular vehicle safety checks and ensure compliance with company fleet policies.
Install and test battery backup systems, UPS units, and power supplies to guarantee continuous operation of life-safety and security systems during power outages.
Adhere to OSHA, company safety policies and safe work practices at all times, including ladder safety, confined space awareness, lockout/tagout for system components when required, and proper PPE use.
Review and verify project scope, materials lists and bill of materials prior to mobilization to prevent on-site delays; communicate shortages or scope changes to project managers promptly.
Participate in continuous improvement by providing field feedback on product reliability, installation best practices, and potential design enhancements to engineering and product teams.

Secondary Functions

Assist sales and estimating teams with technical input for proposals, system scope clarification, and site measurement data to support accurate quotes.
Maintain certification and training records; attend vendor trainings and manufacturer certification courses to remain proficient with new equipment and firmware changes.
Support inventory control processes including part returns, warranty claims, and procurement requests to ensure timely availability of critical components.
Contribute to the development of standard operating procedures (SOPs), installation checklists, and knowledge base articles to improve team efficiency and quality.
Participate in cross-functional meetings with dispatch, monitoring, and project management to improve response times and resolve recurring service issues.
