Model: Wireless Temperature/Humidity

Type: User manual

The Series WM-P Wireless Repeaters are designed to work

with Series WHP and Series WTP wireless humidity and

temperature sensors and Series WM 900 MHz receivers. The

repeaters accept the 418 MHz signal from the transmitting

device and converts it to a 900 MHz signal to send to the

receiver. Repeaters are used in applications where the normal

100 foot wireless sensor range is not enough. They can expand

the measurement range of the wireless sensors to more than

1000 feet.

Wireless products are intended for use in U.S. territories,

Canada and Mexico only.

MOUNTING

Mount the repeater within 100 feet (30.5 meters) of the 418 MHz

transmitting device. The input antenna (418 MHz) should be

mounted to a nonconductive surface or can be left to dangle in

the air. Secure the antenna so that no mechanical stress is

presented to the repeater.

The transmitting antenna (900 MHz) is shipped loose and should

be connected by turning the antenna nut onto the repeater’s

fitting. The repeater should be within 1000 feet (305 meters) of

the 900 MHz receiver.

Repeaters can be mounted to a flat surface, snaptrack or 35 mm

DIN rail. If securing to a surface, use #4 type screws to secure

the repeater.

If the repeater is mounted inside a metal

enclosure, mount the antennas outside of the

enclosure.

TERMINATIONS

The repeater is powered by 9 to 15 VDC. Connect the terminal

labeled “-” to the power supply’s ground. Connect the terminal

labeled “+” to the positive power supply terminal.
