Simpson 260 & UEI Test Meters, Aiphone / Lee Dan / Atlas Intercoms & Alpha / Belden Control Cable
Bench and field diagnostic instrumentation, school and apartment door-entry intercoms, commercial paging horns, and multi-conductor shielded control cable stocked at 149 Congress Street, Lowell.
Diagnostic Meters, Institutional Intercoms & Shielded Control Cable Under One Roof
Elevator mechanics, railroad/transit signal technicians, and plant controls engineers still demand the classic Simpson 260® Series 8 analog VOM because a high-impedance digital multimeter can display 'phantom' capacitive ghost voltages on long control runs and cannot visually track transient needle sweeps on relay contacts or tach-generators.
Alongside test instrumentation from Simpson, UEI, and Hioki, Frank P. McCartin Co., Inc. supports New England schools, housing authorities, and medical offices with Aiphone and Lee Dan apartment/door-entry intercoms, Atlas Sound paging horns, and custom-cut Alpha and Belden shielded instrumentation cable.

Counter Ordering Checklist for Test Meters, Intercoms & Control Cable
- For Simpson 260 repairs & accessories: Note whether your meter uses standard banana jacks or reverse-shrouded safety jacks (Series 8 vs. earlier Series 6/7), and ask for the 1.5V D-cell + 9V battery set and genuine 1A/2A high-breaking-capacity internal fuses.
- For Lee Dan / Aiphone apartment intercom replacements: Count the existing wire conductors at the wall station (3-wire, 4-wire, or 5-wire), measure the flush backbox dimensions, and record the central amplifier model number in the basement.
- For shielded control cable: Specify gauge (AWG), pair or conductor count, solid vs. stranded, overall foil vs. braided shield, and whether the cable runs inside a return-air plenum (requiring CMP / CL2P / CL3P jacket).

Counter Q&A: Simpson Test Meters, Intercoms & Control Wire
Do you stock replacement test leads and internal fuses for Simpson 260 analog multimeters?
Yes. We stock Simpson 260 Series multimeters as well as replacement probe lead sets, alligator clip adapters, protective padded carrying cases, and the special Littelfuse/Bussmann fast-acting fuses required inside the Simpson 260 battery/fuse compartment.
Can we replace a single broken apartment wall intercom station without rewiring the entire building?
Yes. Lee Dan Communications and Aiphone manufacture universal 3-wire, 4-wire, and 5-wire replacement apartment speaker stations (plus oversized stainless-steel retrofit trim plates) engineered specifically to drop into existing Auth, TekTone, Mircom, Nutone, and Couch wall boxes.
What is the difference between a 25V and a 70.7V Atlas Sound paging horn?
An Atlas AP-15T or AP-30T horn includes a multi-tap line-matching transformer selector switch calibrated for both 25V (common in older K-12 school intercom systems) and 70.7V (standard in commercial warehouse paging) constant-voltage amplifier lines, with wattage taps from 1W to 15W/30W.
