Operation, Maintenance, and Troubleshooting

Sensor Batteries

Sensor battery type, length of life, and installation are covered in this section.

Battery Type

CAUTION

 

Equipment Damage!

The batteries are manufactured in a ready-to-use state. They are not designed for 
recharging. Recharging can cause battery leakage or, in some cases, can cause 
the safety release vent to open. 

CAUTION

 

Equipment Damage!

Do not attempt to hook up the WZS to a power supply. Equipment damage may 
result.

Use non-rechargeable 1.5 volt AA lithium batteries in the sensor. Two batteries 
are required. To maintain UL rating, only UL-listed lithium batteries should be 
used. The sensor ships with Energizer™ L91 batteries already installed. 

Note:

The sensor is shipped with an insulation barrier between the batteries 
(

Figure 18

) to prevent discharging of the batteries during shipment and 

storage. Remove this barrier when installing the sensor (see 

“Powering 

the Sensor and Associating the Sensor to the Receiver,” p. 26

).
