Process
How the work moves from survey to support
Design and Scope
Our team creates a detailed alarm design with sensor placement, zone definitions, cabling paths, and monitoring plan, all in a fixed-price proposal.
Install and Configure
NH-based technicians install every sensor, keypad, and communicator. We program zones, configure delays, set up mobile app access, and connect to UL central station.
Training and Monitoring
We train your team on arming, disarming, mobile app operation, and alarm response. Your system connects to our UL-listed central station for 24/7 protection.
Wired vs. Wireless Alarm Sensors
Wired Sensors
- Hardwired to panel via 22-gauge 4-conductor cabling: zero RF interference
- Never needs battery changes: 20+ year maintenance-free lifespan
- Instant communication with panel: no signal delay
- Standard for new construction and major renovations
- Higher install cost in existing buildings (wall fishing required)
VS
Wireless Sensors
- Encrypted RF signals (345/433 MHz): secure communication
- 5–8 year lithium battery life: minimal maintenance
- Installs in minutes: no wall cutting or patching
- Ideal for existing buildings where wiring is disruptive
- Requires wireless receiver within 100–200 ft range
For most NH commercial installations, we recommend a hybrid approach: hardwire main entry points and wireless for interior zones.

Commercial Alarm Systems Built for NH Businesses
Arcomm Communications has been protecting New Hampshire businesses with commercial-grade alarm systems. We build burglar alarm and security alarm systems that deter intruders, detect breaches, and dispatch help, not false alarms that make your staff ignore the siren.
A commercial alarm system needs to detect real threats reliably, communicate with a monitoring station that dispatches police, and integrate with your security cameras and access control so you have a complete picture of every security event.
Dual-Tech Sensors: Eliminating False Alarms
False alarms are the number-one reason businesses lose confidence in their alarm system. We solve this with dual-technology motion sensors that require both passive infrared and microwave detection to trigger. If only one technology detects motion, the sensor holds. The result: near-zero false alarms.
We configure zone types, entry/exit delays, and sensitivity settings for each sensor based on its location. A warehouse sensor needs different tuning than a lobby sensor. Our technicians walk your facility and set every parameter correctly.
Bosch and alarm.com Platforms
Bosch alarm panels are the workhorse of commercial security, modular, expandable, and proven in thousands of installations. Their Solution and B-Series panels support 8 to 240 zones, integrated with access control and video.
Alarm.com provides cloud-connected alarm management with a powerful mobile app, smart automation, and video verification, ideal for businesses that want to arm, disarm, and manage security from any device.
Video Verification: Priority Police Response
Video verification transforms your alarm system from a notification tool into an evidence-gathering platform. When an intrusion sensor triggers, your security cameras automatically capture video of the affected zone and transmit it to the central station operator.
In most New Hampshire jurisdictions, video-verified alarms receive priority police dispatch because the central station can confirm a crime is in progress. Faster response times and higher arrest rates.
Month-to-Month Monitoring: No Lock-In
We offer month-to-month alarm monitoring agreements with no long-term lock-in. If we are not earning your business every month, you should be free to leave. No third-party dealer markups, no hidden fees, no automatic renewal traps.
You get UL-listed central station monitoring, video verification, and mobile app control without committing to a multi-year contract.

FAQ
Frequently Asked Questions
How much does a commercial alarm system cost in NH?
A commercial alarm system in New Hampshire typically costs between $2,000 and $8,000 depending on the number of zones, sensor types, and monitoring level. Single-door retail installs start around $2,000; multi-building campuses with video verification run $6,000–$15,000. We provide a fixed-price proposal after a free site walk, no surprises.
How do you prevent false alarms with commercial alarm systems?
We use dual-technology motion sensors (PIR + microwave) that require both technologies to trigger before alarming, this eliminates false trips from HVAC drafts, animals, and temperature changes. We also configure entry/exit delays and zone types for each door and sensor based on its location.
What happens when a commercial alarm goes off?
The alarm panel transmits a signal to our UL-listed central monitoring station immediately. The operator follows your custom call list, calling the premises first to verify, then dispatching police if no authorized person responds. Video-verified alarms receive priority police response in most NH jurisdictions.
Can I arm and disarm my alarm system from my phone?
Yes. Modern alarm panels support full mobile app control, arm, disarm, check zone status, and receive push notifications for any alarm event. You can also set automated schedules and grant temporary codes to contractors or cleaning staff with time-restricted access.
Wired vs. wireless alarm sensors: which is better?
Wired sensors are more reliable and never need battery changes, making them ideal for new construction. Wireless sensors work well in existing buildings where running wire would require wall damage. Modern wireless sensors have 5–8 year battery life and encrypted signals. We recommend a hybrid approach.
Do you offer alarm monitoring without a long-term contract?
Yes. We offer month-to-month monitoring agreements with no long-term lock-in. If we are not earning your business every month, you should be free to leave. Our monitoring rates are competitive because we own the relationship, no third-party dealer markups.
Can alarm systems integrate with security cameras?
Absolutely. When an alarm triggers, your security camera system can capture video of the zone and transmit it to the central station, this is called video verification. Verified alarms receive priority police dispatch in most New Hampshire jurisdictions, cutting response time significantly.
