Alarm Systems & Fire Protection in Denver
Pulsar serves Denver properties with design, installation, inspection, and 24/7 UL-listed monitoring — burglar alarms and cameras for homes, fire alarm systems for commercial buildings and apartment communities. Trusted since 1974, with systems built around the property rather than sold off a template.
Serving Homes & Businesses Across Metro Denver
Pulsar designs, installs, services, and monitors alarm systems and fire protection for properties throughout the Denver metro and the Front Range — from a single home to apartment communities and commercial portfolios. Whether you're protecting a house in Littleton, a storefront in Lakewood, or a multi-building facility in Aurora, the system is engineered around that property's risks and the code that applies to it. Monitoring runs 24/7/365 regardless of where the property sits.

Denver Alarms & Fire: FAQ
Do you have an office in Denver?
No — Pulsar is headquartered in Plaistow, New Hampshire, with an additional office in Keller, Texas. Denver properties are served by Pulsar's field and monitoring teams, and every monitored system is backed by the same 24/7 UL-listed central-station monitoring our New Hampshire and Texas customers rely on. If a local office matters for your project, tell us and we'll be straightforward about how the work would be staffed.
What kinds of alarm systems do you install in Denver?
Burglar alarms, fire alarm systems, cameras, and access control — for single-family homes, apartment and condo communities, and commercial buildings. Every system is specified for the property rather than sold as a package, and any of them can be connected to our UL-listed central station for 24/7 monitoring.
Do you handle smoke detector installation in Denver?
Yes — as part of a monitored fire or life-safety system. That means interconnected smoke and heat detection wired to a panel that reports to our central station, so an alarm reaches trained operators rather than only sounding in an empty building. We'll specify placement to the code that applies to your property.
Do you work with property management companies in Denver?
Yes. Multifamily communities, HOAs, and commercial portfolios are a large part of what we do — fire alarm systems, access control, cameras, and the pool, elevator, and entry phone lines those properties carry. Managers with buildings in more than one metro often consolidate all of it under one provider, one response protocol, and one bill.
Can you take over monitoring for our existing system?
Often, yes. Many existing panels can be connected to our UL-listed central station with a cellular communicator, so the equipment already on the wall stays in place. Send us your panel details and we'll confirm compatibility before anything is scheduled.
