Table 2:iSTAR Ultra G2 SE and Components Wiring Specifications
■ There are 2 jumpers on the PoE module:
• x1 jumper to select PoE or PoE Plus (+). Ensure the jumpers are set correctly.
• x1 jumper to configure the voltage used to power the Ultra G2. Set the jumper to 24 VDC for the Ultra G2.
NOTE
PoE++ does not require jumpers.
■ Do not connect the PoE injector to a receptacle controlled by a switch.
■ The Tamper, Battery Low, and AC Power Fail inputs must be enabled and connected to report to comply with UL
requirements.
NOTE
AC fail, low battery, and USB cabling must be shielded.
Supervised Inputs must use shielded, 22 AWG (minimum) stranded, twisted-pair cable, such as Belden 9462 or equivalent, for monitor
points, DSMs, and REXs.
Wiring methods must be in accordance with the National Electrical Code, ANSI/NFPA 70.
Connections between PSE or power injector and the PD must use 26 AWG (0.13mm2) for patch cords and 24 AWG (0.21mm2) for
horizontal or riser cables connected through standard 8-pin RJ-45 connectors.
The USTAR-GCM AC Failand COMM, USTAR-GCM, and USTAR-ACM Tamper, USTAR-GCM power, USTAR-ACM power
(Reader), USTAR-ACM connections must remain within 25 feet (7.6 meters) of the control unit.
