Power and cabling tools
PoE budgets, lock power, voltage drop, battery standby and conduit fill for access control and low-voltage work.
- PoE Budget Total switch power required by a device list, with cable loss and headroom against the switch you actually specified.
- Lock Power Budget Power supply size for an access control door set: locks, readers and sensors, the worst-case simultaneous unlock, and the battery standby that follows.
- Voltage Drop What voltage actually arrives at the device on a 12 or 24 VDC run, checked against its minimum operating voltage.
- Battery Standby Amp-hour capacity required to hold a system up for the standby period, with derating for age and temperature.
- Conduit Fill Fill percentage for a conductor list against the NEC limits, with the smallest trade size that passes.
Also in the toolbox: Video surveillance tools, field reference and the technician library.
