This checklist is to help us understand what components and infrastructure may be in place that can be re-used to update your bell ringing system.
- Single Phase (220, 230, 240 or other VAC): Two hot legs, optional Neutral?
- Three Phase (208, 212 or other VAC): Three hot legs
- Existing circuit breaker Amperage
- Supply lead gauge
- Mechanical or digital?
- Condition and type of control cabling to tower
- Relay panel
- Nearby power disconnect?
- Panel dimensions H x W (cabinet Depth)
- Panel mounting bolt size, center to center dimensions
