To comply with UL requirements, use shielded, minimum 22 AWG stranded, twisted pair cable for monitor points, supervised inputs, DSMs, and REXs.
Use Belden9462 or equivalent
.
2
Check wire lengths to verify that voltage drops are acceptable.
Calculations are based on a single RM-4 reader with keypad and LCD (250 mA):
Using 22 AWG, distance = 600 ft. (.0165 W /ft.)
Using 18 AWG, distance = 1500 ft. (.0065 W /ft.)
NOTE
Cables that need to be shielded are described in Table 6-9 on page 6-28.
The Tamper, Low Battery, and AC power fail inputs must be enabled and
connected to the iSTAR Ultra to report for compliance with UL requirements.
For UL listed products, burglar alarm inputs must be supervised.
UL Listed panic hardware shall be used to allow emergency exit from a
protected area.
