System Sensor SSV120-10 10-Inch 120VAC Signal Bell
Overview
The SSV120-10 is a 10-inch signal bell rated for 120VAC operation, purpose-built for audible notification in fire alarm systems, access control installations, and emergency signaling applications. The 10-inch bell body delivers sufficient sound pressure across medium-to-large facility zones without requiring separate amplification hardware. Use this device when you need reliable, code-compliant audible notification tied to networked security platforms or conventional alarm loops.
Compatibility
The SSV120-10 integrates with conventional fire alarm control panels, access control systems supporting networked notification, and TCP/IP-enabled security management platforms. It operates on standard 120VAC circuits found in most commercial buildings—no special power conditioning required. The device is compatible with System Sensor conventional detection platforms and third-party notification systems that accept standard 120VAC audible devices. Verify your control panel's notification output specifications (voltage and current draw) before installation to ensure your circuit can support this bell without nuisance faults.
Installation Notes
Mount the SSV120-10 on a solid surface—wall or ceiling—using the provided brackets and hardware. Verify 120VAC supply voltage is within ±10% of rated voltage before final commissioning. The bell draws current proportional to the coil duty cycle; size your circuit breaker and wiring per NEC Article 760 (fire alarm circuits) to avoid nuisance trips. Position the bell in an area where audible coverage reaches all occupancy zones without acoustic dead spots created by mechanical equipment or large structural elements. Do not install in locations subject to water spray or submersion; this is an indoor device.
