Access Control and Alarm Systems

LONGDWELL SECURITY LLC engineers monitored security, entry control and fire watch for homes and businesses across Herriman and the wider Salt Lake valley. This page sets out the six services on our desk, what each one includes and how a project moves from first survey to a monitored, documented system.

01

Access Control Systems

We design electronic access control that matches the way people actually move through your building. Each project begins with a door schedule that records every opening, its traffic pattern and its risk, and from that schedule we select controllers, readers, credentials and locking hardware. We work with electric strikes, magnetic locks, exit devices and fail safe or fail secure power arrangements so that doors behave correctly during a fire alarm and during a power loss. Credentials can be cards, fobs, keypads or mobile wallets, and every entry is written to an audit trail that can be searched by person, door or time window. For multi tenant buildings we separate rights so one business cannot unlock another business door, and for offices we add door groups and time zones so staff reach their own areas while visitors stay escorted.

24/7 Alarm Monitoring

Our monitoring service watches intrusion, panic, duress and environmental zones at all hours through a supervised connection that reports a lost signal instead of failing silently. Signals reach a staffed monitoring centre where trained operators follow a written response plan agreed with the building owner. That plan states what counts as a confirmed alarm, who is called first, how long the operator waits for a passcode and when emergency services are dispatched. We test the signal path after installation and repeat the test on a fixed schedule, logging each result so the connection is proven rather than assumed. Duress codes and opening and closing reports are configured to your routines, so an out of hours entry is seen as an event rather than treated as normal traffic.

Camera and Video Verification

We pair well placed cameras with alarm zones so an operator can look before making a call, which reduces false dispatches and speeds genuine ones. Our team specifies resolution, lens angle, low light performance, recording retention and storage health per site, then aligns views to the doors, gates and perimeter points that matter most. Video analytics can flag line crossing, loitering or a missing object, and recorded clips export in a format a manager, insurer or police department can open without specialist software. We document the retention window so nobody is surprised by what is still available after an event, and we monitor camera health so a failed channel is raised as a fault before it becomes a blind spot. Where privacy matters, we mask neighbouring property and keep recordings on a schedule that respects your policy.

Fire and CO Detection

Life safety hardware carries the highest stakes, so fire and carbon monoxide installations are engineered, labeled and documented with unusual care. We place smoke, heat and CO devices according to the building layout and the way air moves through it, then interconnect them so an alarm in a plant room reaches the rooms where people sleep or work. Notification appliances, pull stations and monitoring connections report to the same desk that answers intrusion alarms, keeping one contact path for every emergency. We record device addresses, test dates and supervision status, and hand over a simple zone map so any responder can find the panel and the affected area without searching. Scheduled inspections keep batteries, sounders and reporting paths in proven working order.

Entry and Intercom Upgrades

Many older buildings have solid doors and unusable entry systems, with buzzers that fail in bad weather and handsets nobody can hear. Our entry and intercom upgrades modernize the front door without forcing a full building rewire. We replace failed handsets with video stations, add directory panels that stay legible in daylight, and connect the entry point to the access control platform so a granted call also creates an audit record. Delivery drivers, contractors and after hours visitors can be seen and released from a desk or a phone, freeing reception for the people in front of them. In buildings with several entrances we keep intercom groups separate, so a visitor at the rear gate never rings the top floor, and we label every station so residents and staff know exactly who is calling.

Monitoring Plan Management

A monitoring plan is a living document rather than a one time contract. We maintain call lists, passcodes, zone descriptions, response instructions and holiday schedules, and we retire credentials and user records when staff leave. Each year we review what actually happened, adjust zones that generated noise and confirm that the contact path still reaches the right person at three in the morning. Owners receive a plain summary of tests, incidents and changes, which also serves as useful evidence for insurers and auditors. Because one desk holds the intrusion, video and life safety records, the person who answers an alarm already knows the building, the history and the correct next step, and nothing important is lost when a manager changes role.

CALL LISTS ANNUAL REVIEW OWNER SUMMARY

From Survey to Signed Off

Step One — Site Survey and Risk Conversation

We walk the property with the owner or manager, list every door, gate and sensitive area, and talk through what has actually gone wrong before. The output is a written scope, not a verbal estimate, so the work can be compared fairly.

Step Two — Design and Door Schedule

Our engineers produce a door schedule, a zone map and a device list, choose hardware that fits the structure and power available, and show how the system will behave in a fire alarm or a power failure. Owners approve the design before any cable is pulled.

Step Three — Installation and Labeling

Technicians install, label and photograph every device. Cabling is dressed and documented, panels are mounted where they can be serviced, and each reader, camera and sensor is recorded against its own address for future support.

Step Four — Commissioning and Monitoring Handover

We test every zone, prove the signal path to the monitoring centre, program users and schedules, then walk the owner through the system. The handover pack includes the zone map, call list and response plan, and the first round is written into the latch log.

Step Five — Ongoing Review

After go live we keep the plan current, test on schedule and review incidents each year. Zones that generate noise are tuned, credentials are retired, and the owner receives a clear summary of what changed and why.
