Service details
Alarm System Installation in New Hampshire
Arcomm Communications installs commercial intrusion alarm systems for businesses, schools, warehouses, and government buildings across New Hampshire. Our alarm installations include door and window sensors, motion detectors, glass-break sensors, panic buttons, and 24/7 central station monitoring with video verification — designed to protect your property and minimize false alarms.
Alarm Systems We Install
- Commercial burglar alarm panels with zone programming
- Door and window contact sensors
- PIR motion detectors and glass-break sensors
- Hardwired and wireless panic buttons
- Video-verified alarm systems with camera clips
- 24/7 UL-listed central station monitoring
Installation and Configuration
We start with a security assessment to identify entry points, high-value inventory zones, and environmental risks. Our technicians then design a layered detection system, install sensors and the alarm panel, program zone bypasses to reduce false alarms, configure mobile alerts and remote arming, and connect to UL-listed monitoring. Testing includes walk-testing every sensor and verifying signal strength.
Monitoring and Ongoing Support
Our central station monitoring partners verify alarm events before dispatching, reducing false dispatches. Service plans include preventive maintenance, battery testing, sensor calibration, and priority support. Call (603) 464-4600 to schedule a free security assessment.

Customer Proof
Trusted by NH businesses since 1985.
★★★★★
Arcomm wired our 260,000 sq ft distribution center with copper and fiber runs to every workstation. Their crew phased the install so we never slowed outbound shipping.
★★★★★
We run 24/7 CNC machining and cannot afford network drops. Arcomm installed a shielded plant-floor network that has been flawless for 18 months.
★★★★★
HIPAA-compliant access control was non-negotiable for our patient wings. Arcomm installed badge readers and camera coverage with full audit logging. Passes every inspection.
★★★★★
Our school district needed paging that actually reaches every classroom and gym. Arcomm replaced the 30-year-old analog system with IP speakers and district-wide bells.
★★★★★
Arcomm migrated our town hall and DPW to a single VoIP platform. Now residents get through faster and we can forward calls during snow emergencies.
★★★★★
When our server room went down at 2 AM, Arcomm was on-site within an hour. They had us back online before the morning shift arrived. That level of responsiveness is why we use them for all our locations.
