Why Replace Legacy Industrial Autodialers?

Traditional industrial alarm dialers (autodialers) rely on 1990s technology: expensive dedicated hardware, landlines, or dedicated monthly SIM cards, and slow sequential phone trees.

Outdated Tech

Traditional Industrial Autodialers

$500 - $2,000+ Hardware Unit
  • Requires dedicated analog POTS landline ($50-$100/mo) or dedicated SIM contract
  • Sequential phone dialing — calls only 1 person at a time (busy signal stops alerts)
  • No push notifications, no mobile app, no live cloud audit trail
  • Complex landline wiring and single-purpose expensive hardware box
Recommended Solution

MaxLinc EDGE Cloud Alarm Dialer

Included FREE Built-In Feature
  • No dedicated landline or expensive carrier plan — no monthly fee on WiFi; built-in cellular is about $26.67/yr (about $2.22/mo) after the first year, billed annually
  • Simultaneous dispatch — Phone Calls + SMS + Email + Push sent to UNLIMITED recipients at once (with Premium)
  • Full cloud audit trail, app status, and remote alert acknowledgement
  • Universal NO/NC dry contact terminal built into every EDGE environmental logger
Universal Wiring Interface

Universal Dry Contact Compatibility

Connect any voltage-free Normally Open (NO) or Normally Closed (NC) relay switch or sensor directly into the EDGE terminal block:

Generators & Automatic Transfer Switches (ATS)

Receive voice-call and SMS alerts if your standby generator fails or trips an error relay.

Sump Pumps & Liquid Level Floats

Connect a high-water float switch as a secondary fail-safe alert before basement or mechanical room flooding occurs.

HVAC, Chillers & Compressor Trips

Monitor boiler fault relays, air pressure switches, and chiller trip contacts to prevent HVAC breakdown.

Burglar & Fire Alarm Panel Auxiliary Outputs

Interface directly with security panel auxiliary dry contacts to get instant multi-recipient cloud notifications.

Industrial Pressure & Flow Switches

Get notified the instant fluid line pressure crosses high/low safety thresholds or limit switches toggle.

Door & Vault Intrusion Switches

Attach magnetic reed switches to secure cold room doors, server room entries, or sensitive vault doors.

Engineered for Mission-Critical Alerting

Unlimited Recipients with Premium

Never limit emergency alerts to 1 or 2 technicians. Notify your entire operational team simultaneously across multiple phone numbers and email addresses.

Multi-Channel Redundancy

Alerts hit your team across 4 vectors: automated Phone Calls, SMS Text Messages, Email, and Mobile App Push Notifications.

Dual Environmental + Relay Logging

Track ambient temperature, relative humidity, and mold index 24/7 on the same device while monitoring the digital dry contact input.

Remote Acknowledgement & Audit Logs

Track who acknowledged the alert with timestamped cloud records for compliance and operational accountability.

Frequently Asked Questions

What is a Dry Contact Input?

A dry contact input (or voltage-free digital input) is an electrical contact interface that detects whether an external circuit is open or closed (Open/Close). It does not supply voltage; it simply detects contact closure from external relays, switches, or sensors.

How does MaxLinc replace a traditional autodialer?

Traditional autodialers require a dedicated analog landline or paid cellular plan to plug into a wall. MaxLinc EDGE connects to your WiFi or cellular network and uses our cloud infrastructure to generate phone calls, SMS, emails, and app push notifications instantly without needing a physical phone jack or dedicated SIM plan.

How many phone numbers and emails can be notified simultaneously?

With Premium (included for every device's first year, and always on cellular), there is no limit: you can configure an unlimited number of recipients to receive phone calls, SMS text messages, emails, and mobile app push notifications simultaneously the moment the dry contact status changes. On the free Standard tier, everyone already on the list keeps their alerts, but adding someone new needs Premium.

Can I monitor temperature and humidity at the same time?

Yes! The dry contact input is an additional built-in feature on EDGE devices. Your device continues to log ambient (or external probe) temperature, humidity, and mold index while continuously listening for dry contact state changes.
