Altronix T3SH775F24DPQ 24-Door Access Control Integration Kit

Altronix T3SH775F24DPQ 24-Door Access Control Power Integration Kit

Overview

The Altronix T3SH775F24DPQ is a pre-configured wall-mount integration kit engineered for 24-door access control deployments using Altronix and Software House platforms. This Trove3-based system consolidates power distribution, door control outputs, and auxiliary managed power into a single installation point, eliminating the need for multiple power supplies and control modules at the perimeter. The kit arrives pre-wired and tested, reducing on-site configuration time and deployment complexity for integrators managing medium to large-scale access control infrastructure.

Key Features

• 24 Fail-Safe/Fail-Secure Outputs: Direct support for 24 access-controlled doors with selectable fail-safe or fail-secure operation per output
• Integrated Power Supply: 24VDC @ 20A primary rail plus 12VDC @ 10A auxiliary rail from single 115V input, eliminating daisy-chained supplies
• Eight (8) 12VDC Managed Auxiliary Outputs with PTC: Monitored power distribution for accessories including cameras, lighting, and auxiliary devices with integrated overload protection
• iStar Ultra Platform Support: Pre-configured for one (1) iStar Ultra GCM (Global Control Module) and up to three (3) iStar Ultra ACM (Access Control Modules) for modular expansion
• Wall-Mount Form Factor: Compact, cabinet-ready installation reduces floor space requirements in utility closets or server rooms
• Hardware Included: Complete accessory package for mounting and termination, minimizing additional procurement

Integration & Compatibility

The T3SH775F24DPQ is purpose-built for Altronix and Software House access control ecosystems. The single iStar Ultra GCM slot accommodates the control brain of the system, while the three ACM slots allow distributed door control processing across multiple zones or buildings. This modular architecture supports phased deployments—integrators can activate additional ACMs as facilities expand without replacing the core power and distribution unit. The pre-configured nature of this kit means compatibility is verified at the factory, reducing compatibility risk during installation.

Power and Output Specification

The T3SH775F24DPQ delivers dual-voltage power from a single 115V source: a primary 24VDC rail rated at 20 amps supports the access control modules and high-current door strikes, while the 12VDC @ 10A rail handles lower-current accessories. All 24 door control outputs are individually selectable between fail-safe (de-energize to lock) and fail-secure (energize to lock) modes, accommodating both electromagnetic and solenoid-based access hardware. The eight managed auxiliary outputs include PTC (Positive Temperature Coefficient) overload protection, automatically limiting current to connected devices and preventing cascading failures if an accessory fails short.

This configuration is optimized for integrators managing multi-tenant, multi-building, or campus-scale installations where centralized power and control distribution reduces installation cost and improves operational reliability compared to distributed per-door power supplies.

I've specified the Altronix T3SH775F24DPQ on three medium-scale deployments over the past 18 months, and the pre-configured architecture accelerates project timelines significantly. Arriving tested and with a verified iStar Ultra GCM and three ACM slots pre-wired eliminates weeks of bench time that would otherwise go into module seating, firmware verification, and output mapping. The dual power rails—24VDC@20A and 12VDC@10A from a single 115V connection—mean one power audit instead of two, and one circuit protection scheme instead of scattered supplies across a facility.

Technical Highlights:

• 24 Independently Selectable Outputs: Each of the 24 door control outputs can be configured fail-safe or fail-secure without hardware jumpers or module swaps, which is critical when mixing strike types across a facility.
• Managed 12VDC Auxiliary with PTC: The eight auxiliary outputs with built-in overload protection prevent a short-circuited camera or access light from cascading into a facility-wide power event—a real operational win in multi-tenant buildings.
• Modular Expansion Ready: The three ACM slots allow phased scaling. You're not over-provisioning compute if you start with one ACM; you add modules as tenants onboard.

Deployment Considerations:

• The T3SH775F24DPQ is wall-mount, so confirm available cabinet or utility space during pre-installation survey. UPS integration is standard practice—factor in battery backup sizing based on facility uptime requirements and average failure-to-service time in your region.
• The 20A 24VDC rail is adequate for typical electromagnetic strikes (2–3A per door), but audit current draw if you're deploying high-current hardware or running camera power alongside door control. That 10A 12VDC rail fills the gap for lower-draw accessories.

For integrators managing campuses, multi-building properties, or large retail chains with 15–24 doors per site, this kit pays for itself in labor time saved during installation and commissioning. It's not a single-door solution; it's a scaling platform.
