Battery

Each sensor is equipped with a 3.6V lithium

battery, which should be replaced as needed.

The average battery life is 2 years, once the

protective battery tab has been removed.

Schedule battery replacement to avoid a loss

of communications. Sensors will not operate

with an alkaline battery - make sure the

replacement is a 3.6V lithium cell.

The sensor is shipped with a battery pull

tab in place, which turns the device off.

Squeeze the shorter sides of the lid and

remove the sensor’s cover. To activate the

sensor, remove the protective tab to engage the battery. Turn off the sensor by

re-inserting the tab or removing the battery. Any time the sensor is shipped,

it should either be turned off or placed in a shielded container to prevent

interference that might cause shipping problems.

The Heartbeat LED flashes once every ten seconds, and lets a user know the

device is functional.

Installation Mode Switch

The sensor has an installation mode switch - a push

button located under the label in the center of the

enclosure lid. When pressed, the sensor transmits a

data packet with a special mark in its ID field. This

indicates which sensor is in service or being installed.

The data is processed by the Wi-MGR’s Automatic

Discovery feature. For more information regarding

the Wi-MGR and wireless sensor integration, refer to

the Wi-MGR User Guide.

The push button can act as the sensor’s reset switch. It can be pushed after the

battery has been removed and reinstalled, or if the sensor acts erratically. Push

the button to revive the sensor and return it to normal operation.

Troubleshooting

The transmission range of a wireless sensor depends on the distance between

the sensor and the Wi-MGR, and the number of obstacles between the two. The

more obstructions between the devices, the weaker the signal becomes.

Do not install a wireless sensor inside a solid metal cabinet. This can interfere

with its transmission.

Battery Issues

When the protective tab is pulled to activate the battery, the metal terminal clip

on the PC board can bend slightly - not enough to see, but enough to cause

Serial Number

Magnetic Tape

Mount the Sensor

418MHz sensors can transmit 100 feet in open air with limited obstructions.

Wireless sensors should be mounted off the floor. While the electronics are

coated to provide a moisture barrier against condensation, the sensor is

not waterproof and submersion in water is not recommended. To prevent

transmission interference, make sure the side of the sensor with the white RLE

product label faces away from any metal surfaces.

Mount the sensor with 0.5 inch (1.27cm)

wide double-sided adhesive tape or adhesive-

backed magnetic tape. The magnetic tape

will not disturb the electronics, and works well

if the sensor is mounted on a metallic surface.

When placed correctly, the tape allows the

sensor’s label to remain visible. The serial

number on this label is unique to each sensor,

and you will need to refer to this number

throughout the life span of the sensor. If tape

is placed over the label, the paper label will

tear and the serial number will be unreadable.

Mounting holes can be found on the sides of the enclosure, if you wish to mount

it with screws, nails, or other fasteners.
