Edwards Signaling Horns/Strobes, UL 924 Emergency Egress & Electromode Commercial Electric Heaters
Code-compliant auditory/visual plant signaling, 90-minute emergency egress battery units, and heavy-duty electric unit, stairwell, and pump-house heaters for New England commercial and municipal buildings.
Industrial Audible/Visual Signaling, Emergency Egress & Freeze-Protection Heating
Annual fire department walkthroughs, insurance loss-prevention audits, and sub-zero New England January nights expose three critical facility vulnerabilities: failed 90-minute emergency lighting batteries, inaudible plant shift/alarm horns, and frozen sprinkler risers or stairwell entries.
Frank P. McCartin Co., Inc. stocks Edwards Signaling bells, vibrating horns, heavy-duty pushbuttons, and rotating/LED beacons alongside UL 924 emergency lighting units, replacement sealed lead-acid (SLA) and NiCad battery packs, and rugged commercial electric heaters from Electromode (historically cataloged as Electramode) and Cadet.

Commercial Electric Heaters & UL 924 Emergency Egress Matrix
Including genuine replacement parts and cross-references for legacy Electromode (Electramode) cast-aluminum Safety-Grid heaters.
| Equipment Category | Brands Supported | Voltage & Capacity | Key Institutional Advantage |
|---|---|---|---|
| Electromode Cast-Aluminum Electric Heaters | Electromode (Climate Control / Marley / Qmark Cross-Ref) | 120V, 208V, 240V, 277V, 480V • 1.5kW to 50kW | Finned cast-aluminum heating element completely encapsulates the nichrome resistance wire—eliminating exposed glowing coils and shock/lint-fire hazards |
| Commercial Wall, Kickspace & Baseboard Heaters | Cadet Manufacturing | 120V / 208V / 240V • 500W to 4000W | Compact architectural forced-air wall heaters for school vestibules, guard shacks, restrooms, and freeze-prone mechanical closets |
| UL 924 Emergency Lighting & Exit Combos | Satco, Keystone, Dual-Lite / Lithonia Cross-Ref | 120/277V Dual-Voltage Input • 90-Min Battery | High-output LED heads, self-diagnostic test switches, damp/wet-location NEMA 4X housings, and remote-capable units |
| Emergency Light Replacement Batteries | Interstate, Panasonic, Universal SLA / NiCad | 6V & 12V SLA (4Ah–18Ah) • 1.2V–9.6V NiCad Packs | In-stock replacement batteries with F1/F2 spade terminals or polarized wire harnesses to pass annual fire-marshal 90-minute drop tests |
Inspection & Ordering Checklist for Signaling, Egress & Electric Heat
- For Edwards horns and bells: Check the exact coil voltage (24VAC vs. 24VDC vs. 120VAC—an AC vibrating horn will burn out on DC!), gong size, and whether a weatherproof backbox (WBB) is required.
- For Electromode (Electramode) heaters: Record the model number inside the louver cover, voltage (208V vs. 240V vs. 277V vs. 480V), phase (1Ø vs. 3Ø), kW rating, and whether the thermostat/contactor is built-in or remote.
- For emergency light battery replacements: Check battery chemistry (Sealed Lead Acid vs. NiCad), voltage (6V or 12V), Amp-hour capacity, and physical L x W x H dimensions.

Counter Q&A: Edwards Signaling, Egress Lighting & Electric Heat
We have legacy 'Electramode' / Electromode recessed wall heaters in our school corridors—can you get replacement motors and limit switches?
Yes! Electromode (frequently spelled 'Electramode' on older specifications) pioneered the cast-aluminum Safety-Grid element used throughout 1950s–1990s New England schools and municipal buildings. Our Lowell counter cross-references replacement fan motors, thermal cutout limits, contactors, and complete drop-in replacement chassis.
Can I use a 24VAC Edwards 874 horn on a 24VDC fire or PLC control circuit?
No. The Edwards 874 series is tuned for 50/60Hz alternating current; applying 24VDC will overheat the coil. For 24VDC circuits, specify the Edwards 876 series (or multi-mode electronic horn) which includes internal supervisory diode/interrupting circuitry.
Do you stock replacement 6V and 12V backup batteries for emergency lighting inspections?
Yes. Rather than replacing entire emergency light fixtures when a battery fails its annual 90-minute NFPA 101 test, bring your pulled 6V/12V sealed lead-acid or NiCad battery pack to 149 Congress Street for an immediate counter match.
