Command Access CATFT-ML – Frequently Asked Questions

1) Can the Command Access CAT Field Tester run an electric strike or mortise lock without a wall outlet on the job site?
That's the whole point of the CAT Field Tester. It runs off a cordless tool battery, so you can power up an electrified mortise lock, cylindrical lock, electric exit trim, or a solenoid exit device standing at the opening with no outlet and no temporary power run. Output is adjustable 12-24VDC with an LED readout, so you set the voltage the hardware calls for before you energize it.
2) Which tool battery do I need for the CAT Field Tester, and can I use the DeWalt packs I already carry?
You pick the battery platform when you order. The CAT Field Tester comes in three versions: one that takes a DeWalt 20V pack, one for Makita 18V, and one for Milwaukee 18V. Those are the three, and each unit accepts its own platform only, so order the version that matches the batteries already in your van. Battery is not part of the tester.
3) How do I check a power transfer hinge or a door position switch for continuity in the field?
The CAT Field Tester has a dedicated continuity terminal with both an LED and an audible beeper. Put the leads across a power transfer hinge, a switch, or a suspect run of wire and you get a beep and a light on a good circuit, so you can chase a dead electrified opening without setting down a second meter. That covers the usual failure points: the transfer hinge, the switch, and the wiring between the frame and the head end.
4) Should I buy a portable field tester or a boxed access control power supply like the Von Duprin PS902?
They do different jobs and most integrators own both. The CAT Field Tester is a battery powered bench tool for commissioning and troubleshooting: you carry it to the opening, dial 12-24VDC, prove the hardware works, then take it with you. A permanent supply such as the Von Duprin PS902, field selectable 12/24VDC at 2A, or the Securitron AQD1 at 12/24VDC 1A, mounts in the closet and stays there to run the hardware for the life of the installation. Buy the tester to diagnose, the boxed supply to power the door.
5) Which power supply should I use for a motorized latch retraction exit device instead of the CAT Field Tester?
For a motorized latch retraction exit device that needs a dedicated installed supply, the BEST RPSMLR2 Series is a power supply built specifically for motorized latch retraction exit devices. The Command Access CAT Field Tester is used on MLR kits and solenoid-driven exit devices for diagnostics rather than as the permanent feed: it is a portable 12-24VDC adjustable source with a continuity tester for verifying the device and its wiring during install and service.
6) What is the difference between the Command Access CAT Field Tester and a Von Duprin PS902 power supply?
They solve different halves of the same job. The CAT Field Tester is a portable 12-24VDC adjustable supply that runs off a DeWalt 20V, Makita 18V, or Milwaukee 18V cordless tool battery, so it powers hardware where there is no outlet, and it carries a built-in continuity tester with LED and audible beeper for checking switches, power transfer hinges, and wiring. The Von Duprin PS902 is a base power supply rated 2A at 12/24 VDC field selectable for access control, intended to be installed and left in place feeding the opening permanently. A technician commissioning a door typically uses the portable tester on the bench or at the frame and the PS902 as the installed supply.
7) I need a 12/24VDC supply mounted permanently at the door, not a portable one. What are the options?
Several fixed-install supplies cover 12/24VDC. The Securitron AQD1 is a switching power supply at 12/24 VDC 1 Amp, and the Securitron AQL4 is a switching supply at 12/24VDC 4/3 Amp. The SDC 620 Series is a 1 Amp regulated and filtered low voltage supply with dual voltage selection, with the SDC 632 Series at 2 Amp and the SDC 634 Series at 4 Amp in the same regulated and filtered dual voltage family. The RCI DKPS-2A gives 12/24VDC at 2A across 8 outputs for access control systems. The Command Access CAT Field Tester is adjustable 12-24VDC but runs on a cordless tool battery, which makes it a field commissioning and troubleshooting tool rather than the supply you leave in the wall.
8) I need to power several electrified doors from one panel. Is the CAT Field Tester the right choice?
No, that is a multi-output enclosure job. The Altronix AL1024ULACMCB is a power supply and access power controller with 115VAC 60Hz input at 4.2A, eight PTC outputs, and 24VDC at 10A in a grey enclosure. The RCI DKPS-2A provides 8 outputs at 12/24VDC 2A for access control systems, and the Locknetics LP Series comes with an enclosure. The Command Access CAT Field Tester is a single portable 12-24VDC source a technician carries to one opening at a time to power and verify hardware.
9) Will a 12-24VDC field tester cover the voltage range of commercial electrified locking hardware?
Yes. The adjustable 12-24VDC output spans the range electrified locking and access control devices are built for, and the integrated LED display shows the actual output while you turn it, so you can confirm you're at 12V or 24V before the hardware sees power rather than guessing at a dial position.
10) What leads and connectors come with the CAT Field Tester, or do I have to make up my own?
A CAT connector harness and alligator clip leads ship with the tester. The harness handles hardware that terminates in a CAT connector, and the clips let you land on bare leads, a terminal strip, or a hinge pigtail. You supply the battery.
11) Is a plug-in mini power supply like the ROFU 9126T a substitute for the CAT Field Tester?
They are not interchangeable. The ROFU 9126T is a plug-in mini power supply rated 12 VDC / 1.5A with time delay, so it needs a receptacle and delivers a single 12 VDC level. The Command Access CAT Field Tester is adjustable across 12-24VDC with an LED voltage display and runs from a DeWalt 20V, Makita 18V, or Milwaukee 18V cordless tool battery, so it works at an opening with no power available and lets you dial the voltage to the device under test.
12) What do I need if the opening requires power to stay up during a utility outage?
That calls for a supply with backup rather than a field tester. The Adams Rite PS-1 is a regulated power supply, 1 Amp, 12/24 volts DC with battery backup. The Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup. The Securitron BPSS is a boxed solar power supply. The Command Access CAT Field Tester carries its own cordless tool battery, but its role is powering and testing hardware during commissioning and service work rather than holding an installed opening up through an outage.
13) I need a UL listed 12V supply for an access control kit. Which product covers that?
The Aiphone AC-PS1250 is a power supply for AC Series access control kits, 12V DC 5A and UL listed, which is the fixed supply that feeds an installed kit. The Command Access CAT Field Tester is a portable, adjustable 12-24VDC source carried to the opening for commissioning and field verification of electrified door hardware, so it complements that installed supply rather than replacing it.
14) Is the ROFU 10305-LA a comparable item to the CAT Field Tester?
No. The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V in a plastic white finish, which is the path that carries power from the frame into the door leaf. The Command Access CAT Field Tester is a portable 12-24VDC supply whose continuity tester is used to check power transfer hinges and wiring for integrity, so the two are used together rather than one in place of the other.
15) I need 10 amps at 12VDC for a bank of maglocks. What should I look at?
The Securitron AQS1210 is a switching power supply at 12 VDC 10 Amp, and the Altronix AL1024ULACMCB delivers 24VDC at 10A across eight PTC outputs from a 115VAC 60Hz input. The Command Access CAT Field Tester is not the item for that load: it is a portable 12-24VDC tester and supply run from a cordless tool battery, sized for commissioning and troubleshooting a device at a time.
16) I'm doing access control commissioning across a healthcare campus. Is this a commercial grade tool?
The CAT Field Tester is a commercial product, built for field service and maintenance in commercial, healthcare, and institutional facilities. It's the tool for walking a punch list of electrified openings: energize each device at its rated voltage, ring out the transfer hinges and switches, and verify the system before the panel is turned over.
17) Can a control module like the BEST ELR150 be used in place of the CAT Field Tester?
They are different devices. The BEST ELR150 Series is a power supply control module for electronic access control, a component of the installed power and control chain at the opening. The Command Access CAT Field Tester is a self-contained portable 12-24VDC supply with an LED voltage readout and a continuity terminal, used to energize hardware and verify switches and wiring in the field without a wall outlet.
