B4Z-855-NODENode Repeater

1 D†‡hyyh‡v‚ D†‡…ˆp‡v‚† B@D‡r…y‚tv‘ 9 Product Summary The Node Repeater reduces wireless traffic and extends the range of GE Interlogix wireless sys- tems. It receives signals from GE Interlogix 319.5MHz sensors, then retransmits them if neces- sary. The Node Repeater incorporates a 900MHz transmitter for increased range. The Repeater allows enrollment of up to 128 sensors. Only enrolled sensors are monitored and repeated. Sensors are enrolled into the Node Repeater using either a personal computer interface or a pair of on-board DIP switches. Power is supplied to the Node Repeater via a 16.5VAC Class 2 transformer. A 12V lead acid battery provides backup power. Repeater Features: •Regular supervisory reports to the panel •A tamper switch that causes an alarm transmission if the cover is removed. •A tamper switch that causes an alarm transmission if the unit is removed from the •wall. •Antenna tamper monitoring, causing an alarm transmission if the antennas are cut. •Dual receive antennas, which provides improved reception through spatial •diversity. •Receiver jam detection, with an alarm transmission if jam is detected. •Sensor enrollment using either a PC or DIP switch interface. •Support for a rechargeable lead acid backup battery. •Battery monitoring, with an alarm transmission if the battery is low. •AC power monitoring, with an alarm transmission if the power has failed for •more than 15 minutes. •Encryption of sensitive data.

These switches are used for enrollment and deletion of sensors. The following table shows the modes of operation based on switch settings, with 0 = Off and 1 = On. These modes are discussed further in the section on enrollment below.

Note that a PC is required for initial configuration regardless of the method of sensor enrollment. The following are the basic steps of each method. The steps are described more fully in later sections. Installation using a PC 1. Mount the repeater board in the enclosure. 4 QuikBridge Node repeater Installation Instructions 2.

RF Exposure Compliance Statement The following discussion will establish compliance of this transmitter with FCC MPE regulations. It may be viewed as an addendum to §3.6.3 of the original report. 1.1 Peak Radiated Power for Purposes of RF Exposure Compliance Exhibit U of the original report shows that the peak output power of the transmitter is 23.6dBm. §3.3.3 of the original report shows that the gain of the DUT antenna is 1.95dBi. The transmitter peak radiated power is therefore obtained as follows: Peak Radiated Power = 23.6dBm + 1.95dB = 25.55dBm As allowed in §2.1091(d)(2), source-based time averaging may be used to reduce the declared RF exposure level. This transmitter has inherent duty cycle properties that may not be modified by the user and therefore fall under the source-based time averaging provision. The following is the derivation of the allowed correction factor for this transmitter. The transmitter employs amplitude modulation and transmits 208 bits. Each bit has an “ON” time of 122 μS. The total on time of a single packet is: 208 * 122 μS = 25.376 msec. The interpacket delay time of 45mS, enforced by the software, ensures that only one packet is sent in any given 100mS window. The duty cycle correction factor is therefore: 20*LOG( 25.376/100) = -11.91 dB Using the above peak radiated power and duty cycle correction factor, the peak power of this transmitter for determination of RF exposure levels is: P = 25.55dBm – 11.91dB = 13.64dBm = 23.12mW 1.2 FCC RF Exposure Limit For the purposes of demonstrating RF exposure compliance, the limits for general population/uncontrolled exposure in §1.1310 will be used. Table 1B of this section gives the allowed power density as: Power Density Limit = f/1500 = 915/1500 = 0.61mW/cm 2 GE Interlogix, Inc RF Exposure Addendum.doc 09/11/03 2:37 PM FCC ID: B4Z-855-NODE Page 4 of 4 1.3 Calculation of Distance from Transmitter to Reach FCC Exposure Limit The distance from the transmitter at which the allowed power density limit is reached may be calculated using the general relation: Power Density = (Power Transmitted)/4πr 2 Solving for r, the distance from the transmitter, we have r = sqrt(P t /4πP d ) Substituting the allowed FCC Exposure limit for P d and the transmitter peak power for P t , we have: r = sqrt(23.12mW/4π(.61mW/cm 2 )) = 1.74 cm 1.4 Discussion and Conclusion This result shows that a person must be within 1.74 cm of this transmitter in order to be exposed to the FCC RF exposure limit as given in §1.1310. Note also that this analysis assumes that the transmitter would be sending data packets continuously, which is not a realistic mode of operation. In an actual installation with 128 sensors installed, the on- time of the transmitter would be reduced from this number by a factor of 100 or more. This device is intended to be permanently mounted in a fixed location. The preceding analysis shows that a person must essentially be touching the device in order to be exposed to the FCC RF exposure limit. Because of the unlikelihood of this situation and its incongruence with the intended use of the product, warning or caution labels regarding RF exposure are not necessary and will not be affixed to the device.

Introduction This device is a radio repeater. It receives and processes data from existing GE Interlogix 319.5MHz sensors. If required, it transmits information via a 902 - 928MHz Frequency Hopping Spread Spectrum (FHSS) link to a base station receiver, which may in turn be connected to a personal computer or security panel via a hardwired connection. The transmitter uses the 902-928MHz ISM band, operating as a FHSS device. We are requesting Certification under FCC Rules, Part 15, Subpart C, Paragraph 15.247. Power is supplied to the device via a 16.5VAC Class 2 transformer. A 12V lead acid battery provides backup power. The enclosure measures approximately 6.75′′ by 6.25′′ by 2.25′′. The antennas protrude approximately 9.25” above the enclosure. The unit weighs approximately 3 pounds, 4 ounces, including battery and transformer.
