EN1501-EXT Pulse Counting Transmitter for
Integration
Installation and Operation Manual - 06289A
1 Overview
The EN1501-EXT pulse counting transmitter for integration is a board-only transmitter
with external header pins. It is designed for integration into a customer-designed
meter or product. The EN1501-EXT is for use in Australia, New Zealand, and North
America.

Housing tamper switch Sends an alert message when the housing is opened.
Removable terminal block Allows connection to an external meter.
Reset input Connects a reset input to send a reset message when prompted by the
user-specific end-device.
Tamper input Connects a tamper input to send a message when the user-specific
end-device is tampered with.
Count input Connects a count input to increment the meter count.
Power output Allows for another device to share battery power.
Ground Connects to the ground.

4 Installation
A The EN1501-EXT must only be connected at the four pin header.
B All cables and wires must be routed away from the component side of the EN1501-
EXT.
C The on-board antenna must not be tampered with; no connection to an alternate
antenna is provided.
D The meter or product must not include an integrated secondary colocated radio
module.
E The EN1501-EXT on-board antenna should be placed so that it is facing away, or
otherwise isolated from, your device’s ground plane.
F Components that are sensitive to RF transmission, such as high gain circuits,
should be isolated from the on-board antenna to prevent interference.
G EN1501-EXTs should not be mounted on metal surfaces or inside metal
enclosures. They should also not be mounted where sheet metal ductwork, wire
mesh screens, etc. might block transmissions.
5 Pulse Counting Transmitter for Integration
Requirements
5.1 Power
Power is supplied by the on-board 3v battery. The power pin allows for another device
to use this power source, which can affect battery life.
The low battery flag is set when the measured voltage is less than 2.4 v.
5.2 External Tamper Requirements
The housing tamper switch and tamper pin have the same specification. Connecting
the tamper pin to ground initiates the tamper condition. Once a transition (tamper
connected/disconnected from ground) is detected, no further transitions can be
processed for a debounce time of 250 ms.
5.3 Count Requirements
The removable terminal block and count pin have the same specification. On the
terminal block, the outer terminal is the negative terminal if polarity is present from the
connected meter.
The count is incremented by connecting the count to ground or receiving a contact
closure from a pulse-output meter via a wired connection. In general the contact
closure should meet the following characteristics:
• a minimum switch output pulse width of 10 ms or longer.
• a maximum rate of one pulse every four seconds (slower is better).
• a closed impedance smaller than 1k ohm.
• an open impedance greater than 5 Mega ohms.
• hardware latched input transitions from the external device.
Once a latched input is detected, no further transitions will be processed for a
debounce time of 350 ms.
The count totalizer corresponds to the number of totalizer input pulses. The counts
accumulate until the number 9,999,999 is reached. The totalizer will then go to zero
on the next count.
6 Compliance Requirements
6.1 FCC Requirements for the EN1501-EXT
The EN1501-EXT has received a Limited Modular Grant, requiring Inovonics to retain
control of the final installation to ensure compliance to FCC/IC regulations. The
integrator is responsible to test the final installation to verify compliance to FCC/IC
regulation for unintentional emissions.
Prior to marketing the product, the integrator must complete and submit to Inovonics a
compliance review form and documentation, and, if requested, a functional product
sample for approval. If this is not possible, the integrator must perform the testing
themselves and submit proof to Inovonics of compliance to Part 15 of the FCC Rules
and Industry Canada ICES-003.
At the end of this guide is an Inovonics compliance review form to be filled out by the
integrator.
The integrator is also responsible for properly labeling the product containing the
EN1501-EXT. Labels must be placed on the outside of the product, and must include a
statement indicating that the product contains the EN1501-EXT, along with the FCC
and IC number.
Example 1 “Contains EN1501-EXT Pulse Counting Transmitter
FCC ID: HCQ3B6OTPMTX; IC ID: 2309A - OTPMTX
Example 2 “Contains FCC ID: HCQ3B6OTPMTX; IC ID: 2309A - OTPMTX
6.2 Television and Radio Interference
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
