Edwards Signaling 661, Flush Buzzer "BUZACALL"

Designed to deliver dependable audible notification in tight spaces, the Edwards Signaling 661 Buzacall flush buzzer is a practical addition to any fire alarm control panel accessories kit. As a low-voltage security buzzer operating at 8–10 VAC (50/60 Hz) and drawing up to 1.5 A, the 661 offers clear, consistent tones ideal for door signals, interoffice communications, and routine monitoring tasks. Its compact strap-mounted design and 1" depth allow flush mounting in standard outlet boxes for a discreet, professional installation that preserves wall and panel aesthetics.

The Buzacall 661 integrates easily into existing systems — it requires a standard 590 transformer and compatible push button, both of which may be co-located in a single 3-gang box when space permits. Built by Edwards Signaling (UTC Fire & Security), this security buzzer is engineered for commercial and residential applications where reliable audible notification supports surveillance, monitoring, and life-safety workflows. Add the 661 to your next project specification to simplify installation and maintain consistent audible coverage — ideal for retrofits and new builds alike.
