PTM 335 / 335C

4.2 FCC (United States) Certification

PTM 335C LIMITED MODULAR APPROVAL

This is an RF module approved for Limited Modular use operating as an intentional trans-

mitting device with respect to 47 CFR 15.231(a-c) and is limited to OEM installation. The

module is optimized to operate using small amounts of energy, and may be powered by a

battery. The module transmits short radio packets comprised of control signals, (in some

cases the control signal may be accompanied with data) such as those used with alarm

systems, door openers, remote switches, and the like. The module does not support con-

tinuous streaming of voice, video, or any other forms of streaming data; it sends only short

packets containing control signals and possibly data. The module is designed to comply

with, has been tested according to 15.231(a-c), and has been found to comply with each

requirement. Thus, a finished device containing the PTM 335C radio module can be oper-

ated in the United States without additional Part 15 FCC approval (approval(s) for uninten-

tional radiators may be required for the OEM’s finished product), under EnOcean’s FCC ID

number. This greatly simplifies and shortens the design cycle and development costs for

OEM integrators. The module can be triggered manually or automatically, which cases are

described below.

Manual Activation

The radio module can be configured to transmit a short packetized control signal if trig-

gered manually. The module can be triggered, by pressing a switch, for example.

The packet contains one (or more) control signals that is(are) intended to control some-

thing at the receiving end. The packet may also contain data. Depending on how much en-

ergy is available from the energy source, subsequent manual triggers can initiate the

transmission of additional control signals. This may be necessary if prior packet(s) was

(were) lost to fading or interference. Subsequent triggers can also be initiated as a precau-

tion if any doubt exists that the first packet didn’t arrive at the receiver. Each packet that is

transmitted, regardless of whether it was the first one or a subsequent one, will only be

transmitted if enough energy is available from the energy source.

OEM Requirements

In order to use EnOcean’s FCC ID number, the OEM must ensure that the following condi-

tions are met:

 End users of products, which contain the module, must not have the ability to alter the

firmware that governs the operation of the module. The agency grant is valid only when

the module is incorporated into a final product by OEM integrators.

 The end-user must not be provided with instructions to remove, adjust or install the

module.

 The Original Equipment Manufacturer (OEM) must ensure that FCC labeling require-

ments are met. This includes a clearly visible label on the outside of the final product.

Attaching a label to a removable portion of the final product, such as a battery cover, is

not permitted. The label must include the following text:

Contains FCC ID: SZV-PTM335C

The enclosed device complies with Part 15 of the FCC Rules. Operation is subject to

the following two conditions: (i.) this device may not cause harmful interference and
