EDWARDS A52844458 – IQ Interface Module | EST IQ Series Fire Alarm Platform
The EDWARDS A52844458 IQ Interface Module is a critical integration component within the Edwards Systems Technology (EST) IQ Series intelligent fire alarm and life safety platform. Carrying cross-reference part numbers ML25995 and 0190-02362, this module serves as the communication and signal bridge between the IQ Series fire alarm control panel (FACP) and third-party or ancillary building systems — enabling coordinated emergency response across complex facility environments.
Procurement engineers and system integrators specify the A52844458 when upgrading legacy EST installations, expanding existing IQ Series networks, or sourcing verified OEM replacement modules for mission-critical life safety infrastructure. Konmask.com supplies this module from traceable, quality-verified channels with full documentation support.

Engineering Advantages
- OEM Verified: Genuine EDWARDS part — ensures full firmware and hardware compatibility with existing IQ Series installations without field modification.
- Multi-Protocol Interface: Bridges IQ Series proprietary signaling with standard dry-contact, supervised relay, or serial communication outputs depending on configuration.
- Supervised Signal Paths: All interface connections are supervised for open/short fault detection, maintaining system integrity per NFPA 72 requirements.
- Hot-Swap Compatible: Designed for in-panel replacement with minimal system downtime — critical for occupied facilities.
- Backward Compatible: Supports integration with earlier EST IQ Series panel generations, protecting existing infrastructure investment.
- Reduced Engineering Risk: Using the exact OEM part number eliminates compatibility uncertainty versus generic or third-party alternatives.
System Architecture & Signal Flow
The A52844458 IQ Interface Module installs directly into the IQ Series FACP chassis backplane. In operation, the module receives alarm, supervisory, and trouble signals from the IQ Series main CPU and translates these into configurable output formats — including relay contacts, supervised wiring loops, or serial data — for downstream system consumption. Incoming signals from third-party systems (e.g., suppression release confirmation, door holder status) are received, supervised, and reported back to the FACP as monitored input points. This bidirectional architecture ensures the FACP maintains full situational awareness of all integrated subsystems, enabling coordinated, code-compliant emergency response sequences.

Technical FAQ
Q: Is A52844458 compatible with all IQ Series panel versions?
A: The A52844458 is designed for the EST IQ Series platform. Compatibility depends on specific panel model and firmware version. Contact our team with your panel model number for confirmation before ordering.
Q: What is the difference between A52844458, ML25995, and 0190-02362?
A: These are cross-reference part numbers for the same physical module used across different EDWARDS/EST ordering systems and regional catalogs. All three refer to the identical IQ Interface Module.
Q: Can this module be used as a direct replacement in an existing installation?
A: Yes. As a genuine OEM part, the A52844458 is a direct drop-in replacement for failed or end-of-life interface modules in compatible IQ Series panels, with no firmware changes required in most configurations.
Q: Do you provide installation documentation?
A: Yes. EDWARDS installation manuals and wiring diagrams are available upon request. Contact support@konmask.com.
Q: What is the lead time for this module?
A: Lead time varies by stock availability. Contact us for current inventory status and expedited shipping options.
