EN1501 Pulse Meter Transmitter

Installation Instructions

1 Overview

The EN1501 pulse meter transmitter is a pulse counter which can be used

for water, gas and electric submetering applications.

The pulse meter transmitter is available in North America, Australia and

New Zealand; the radio frequency band has been configured for the

appropriate geographic area at the factory.

1.3 What’s In The Carton

• Fifty drywall anchors.

• Fifty mounting screws.

• Fifty pieces of mounting tape.

2 Installation and Startup

2.1 Installation Notes

• These products are designed to be maintained by professional

technicians.

• Products are tested for indoor use.

• A maximum rate of six pulses per second.

• Closed impedance of the pulser mechanism must be smaller than 1k

ohm.

• Open impedance of the pulser mechanism must be greater than five

megohms.

2.3 Connect Transmitter to Meter

Connect the transmitter to the meter as follows:

1. Open the housing by pressing down on the base tab near the wiring

through-hole while lifting away the cover.

2. Fully insert stripped wires into the removable header terminal.

corner of the board.

2.4 Mount the Transmitter

1. Use the double-sided tape to mount the transmitter to a clean wall.

2. As desired, secure the transmitter to the wall with the mounting screw

and anchor.

Note: To secure the EN1501, you will need to remove the battery to access

the mounting screw hole. Make sure to press the reset button after

replacing the battery to initialize the transmitter.

2.5 Register the Transmitter

1. Confirm that transmitter is connected to the meter.

2. Confirm that the battery is installed.

3 Replace the Battery

When the low battery message is received, you will need to replace the

EN1501 battery.

1. Open the housing by pressing down on the base tab near the wiring

2. Remove the old battery, taking note of the battery orientation.

3. Insert the new battery, making sure it is aligned correctly.

4. Press the reset button.

Note: EN1501 transmitters retain programming data in non-volatile

memory. They do not require reprogramming after loss of power. Install

non-condensing.

Typical battery life: EN1501: 10 year battery life in a climate controlled

environment with the specified Panasonic CR123A battery.

EN1501 Battery (BAT604): Panasonic CR123A 3.0V lithium battery. The

battery is always supervised.

5 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

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.

6 FCC Part 15 and Innovation, Science and

Economic Development Canada (ISED)

Compliance

This device complies with part 15 of the FCC Rules, and ISED license-

exempts de licence. L'exploitation est autorisée aux deux conditions

suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur

de l'appareil doit accepter tout brouillage radioélectrique subi, même si le

brouillage est susceptible d'en compromettre le fonctionnement.

7 Radiation Exposure Limits

7.1 FCC

This equipment complies with FCC radiation exposure limits set forth for an

uncontrolled environment. In order to avoid the possibility of exceeding the

FCC radio frequency exposure limits, human proximity to the antenna shall

not be less than 20 cm during normal operation and must not be co-located

transmitter.

Cet équipement est conforme avec ISED RSS-102 des limites d'exposition

aux rayonnements définies pour un environnement non contrôlé. Cet

émetteur doit être installé à au moins 20 cm de toute personne et ne doit

pas être colocalisé ou fonctionner en association avec une autre antenne

ou émetteur.
