Eaton Wheelock DSM-12/24-R — red dual sync module converting separate strobe and audible panel inputs into one synchronized two-wire output.
It makes a run of Wheelock appliances flash and sound together, producing the NFPA 72 temporal Code 3 pattern with a synchronized flash, and keeps the strobes lit when the horns are silenced.
- Drives one Class A or two Class B notification appliance circuits, 3 amperes per circuit at 12 or 24 Vdc
- Average current 0.020 A at 12 Vdc and 0.035 A at 24 Vdc; UL maximum 0.055 A
- Regulated range 8.0 to 33.0 volts, filtered DC or unfiltered full wave rectified
- Up to 20 modules daisy chained for as many as 40 circuits, within 1,000 feet of 18 AWG
- Screw terminals take 18 to 12 AWG; mounts to a 4-11/16" by 2-1/8" deep backbox
- UL 1971 listed, ULC to CAN/ULC-S525 and S526, plus CSFM, NYC MEA and Chicago BFP
Eaton lists one DSM model, order code 6374 in red, and only one DSM is allowed per signalling circuit. MT multitone horns and CH70 chimes synchronize their strobe through it but not their audible portion, unlike the AH-WP, AS-WP, RSS/RSSP and Eluxa appliances.
