Transmitter” on page 2)

Battery Installation
1. Remove the rear housing cover to expose the side of the board that 

holds the battery.

Caution: Carefully separate the rear housing cover, ensuring the reset 
button plunger assembly does not fall out of the housing (Figure 2).

2. Slide the battery under the battery holder, ensuring that it is fully 

inserted and that the positive terminal (+) faces up (Figure 2).

Select the Frequency Band
EchoStream products are able to use a range of radio frequencies, and 
must be configured for your geographic area. This product ships with a 
default frequency range of 902-928 MHz for use in North America. If you 

are using the product in North America, skip to step 6; if you are using the 
product in Australia or New Zealand, you will need to configure the 
transmitter.
To configure the transmitter:
3. Turn the board over to access the side with the frequency band 

selection pins (Figure 2).

4. Place the frequency band selection jumper on the appropriate 

frequency band selection pins.

• Place the jumper on the left two pins, marked AU, to set the frequency 

range to 915-928 MHz for Australia.

• Place the jumper on the right two pins, marked NZ, to set the 

frequency range to 921-928 MHz for New Zealand.

5. Seat the board in the housing with the battery side facing the rear 

housing cover. 

6. Replace the front housing cover.
7. Insert the three housing screws, tightening them to 1.25 inch-pounds 

torque. 

Note: If you do not have a torque driver, tighten to a snug fit, being careful 
not to overtighten.

Note: Tighten the housing screws evenly to help ensure a good seal and 
maintain water-resistance.

Caution: Over-tightening the housing screws can result in microcracks in 
the plastic, gaps in the gasket material, and/or stripping of the bushing. Any 
of these conditions can compromise the water-resistance of the device.

Register the Transmitter
The transmitter must be registered and supervised. When supervised, the 
transmitter will send check-in message to the receiver or gateway as 
follows:

• EN1223D: every three minutes.
• EN1223D-15: every 15 minutes.

Each transmitter has a unique factory-programmed identification number. 
Refer to the receiver or gateway's installation instructions for details on 
registering and setting up supervision.
8. When prompted by the receiver or gateway to reset transmitter, press 

the reset button (Figure 1).

Caution: The transmitter should be tested after registration to ensure 
operation. See “Test the Transmitter” on page 2.

To send an alarm, press both activation buttons simultaneously for at least 
one second. Alarm signals are transmitted multiple times and are indicated 
by the blinking transmission LED. When the buttons are released, the 
transmitter sends an alarm restoral signal as indicated by another short 
series of blinking transmission LED lights.

The pendant transmitter can be worn in three ways:

• Around the neck with neck chain attachment (included)
• On a belt with the beltclip attachment (included)
• On the arm with optional wristband accessory (ACC623S or 

ACC623L, sold separately)

Caution: The neck chain included with the pendant transmitter is designed 
with a breakaway feature for user safety. Substitution of a stronger cord or 
chain may result in injury to the wearer.

Note: The optional wristband accessory is not part of the UL listing.

All EchoStream water-resistant pendants meet IP54 certification standards 
for dust and water ingress protection, ensuring that:

• Ingress of dust particles does not interfere with the satisfactory 

operation of the device

• There is no harmful effect to the device caused by:

-  Vertically dripping water (when device is tilted up to 15° from normal 

position)

-  Spraying water (falling at angles up to 60° from vertical)
-  Splashing water (from any direction)
