Visonic Ltd. FCC ID:WP3MP872PG2
IC: 1467C-MP872PG2

Exposure limit according to §15.247(i)

The Smart Wireless Ceiling PIR Presence/Security Detector, MP-872 PG2 is classified as a mobile device.

The FCC limit for power density for general population/uncontrolled exposure is f/1500 mW/cm 2
for 300 – 1500 MHz frequency range:

P = 912.75/1500 = 0.61 mW/cm2

The power density P (mW/cm2) = PT / 4 r2

PT is the transmitted power, which is equal to the peak transmitter output power 18.24 dBm plus maximum
antenna gain -1 dBi, the maximum equivalent isotropically radiated power EIRP is

PT = 18.24 dBm + (-1) dBi = 17.24 dBm = 53 mW .
The power density at 20 cm (minimum safe distance, required for mobile devices), calculated as follows:

Compliance with FCC limit: 53 mW / 4 (20 cm) 2 =0.0106 mW/cm2 << 0.61 mW/cm2

General public cannot be exposed to dangerous RF level.
