Technical FAQs

Q1: What is the primary function of the Honeywell AMPS-24E?

The AMPS-24E is an addressable power supply and battery charger. It provides DC power for compatible fire alarm equipment while communicating system status through an addressable interface.

Q2: What is the difference between AMPS-24 and AMPS-24E?

The main difference is the AC input voltage configuration. The AMPS-24 is designed for 120 VAC applications, while the AMPS-24E is designed for 220–240 VAC, 50/60 Hz installations.

Q3: Which communication protocols does the AMPS-24E support?

It supports NOTIFIER FlashScan and CLIP (Classic Loop Interface Protocol) operating modes. The selected mode must be compatible with the connected fire alarm control panel.

Q4: Which fire alarm control panels can work with the AMPS-24E?

The AMPS-24/E is designed for compatible NOTIFIER systems, including the NFS-3030 and NFS2-3030 fire alarm control panels. It can also be used as a power supply for the NCA-2 Network Control Annunciator in supported configurations.

Q5: Does the AMPS-24E include a battery charger?

Yes. It includes a charging circuit for compatible sealed lead-acid batteries. Charging current is selectable according to the system configuration and battery requirements.

Q6: What battery capacity can the AMPS-24E support?

The manufacturer's documentation specifies support for battery capacities from 7 Ah to 200 Ah, subject to the selected charging configuration and applicable installation requirements.

Q7: What happens if the AC power supply fails?

The system can report AC power loss through its supervision functions. The connected battery arrangement provides secondary power when configured correctly and within the system's specified operating limits.

Q8: What is the purpose of the isolated SLC interface?

The isolated Signaling Line Circuit interface supports addressable communication between the power supply and compatible fire alarm control equipment.

Q9: What should be checked if the AMPS-24E reports a power fault?

Inspect the AC input, battery connections, battery condition, output wiring, fuse status, and system configuration. Review the fire alarm control panel's trouble information to help identify the reported fault.

Q10: Can the AMPS-24E replace a standard 24 VDC power supply?

Not automatically. It is an addressable fire alarm power supply with specific communication, charging, and supervision functions. Any replacement must meet the original system's electrical, functional, and certification requirements.
