2 Installation and Startup

2.1 Installation Notes

• These products are designed to be maintained by professional 

technicians.

• Products are intended for indoor use.
• Do not ship the pendant with the coin cell battery installed when 

temperatures are below 32°F. Doing so will damage the internal 

battery and cause the pendant to irretrievably fail.

• All products should be manually tested weekly (see section 6, “Test 

the Transmitter”).

2.2 Coin Cell Battery Installation

Caution: 

If you are installing batteries in multiple devices, keep the 

batteries from coming into contact with each other to prevent discharge.

1.

Place the battery in the battery compartment, ensuring that the positive 

terminal (+) faces up.

2.

Seat the battery door over the battery so that the arrow on the battery 

door is lined up with the unlocked padlock icon.
