Decision-Maker Fire Alarm Email List

I need a fresh, well-verified email list of key decision makers at fire-alarm focused companies across the United States and Canada.
The companies must fit one of these profiles: fire alarm system integrators and distributors, turnkey fire alarm and low-voltage subcontractors, firms that offer both fire alarm and low-voltage services, or clean-agent / fire-suppression installers and suppliers. Please exclude general electrical contractors that do not specialize in life-safety systems.

Within those firms I only want contacts who truly steer technical or business direction:
• Engineering, design, and NICET-certified Level III/IV leaders (Engineering Manager, Design Manager, Fire Alarm Designer, etc.)
• Operations and project management leadership (Operations Manager, VP of Operations, Project Manager – Fire Alarm/ELV)
• Owners or principals of small- to mid-size integrators.

Deliverables I expect:
1. Spreadsheet (Excel or Google Sheets) with columns: First Name, Last Name, Exact Title, Company, City/State/Province, Email, Phone (if available), Website/LinkedIn source link.
2. Minimum 95 % valid emails (I will test with a bulk verifier). Hard bounces above 5 % must be replaced.
3. At least one decision-maker contact per company; more where available.

Let me know your typical data sources and the volume you can supply so we can set milestones accordingly.
