DSC WLS907T Wireless Low Temperature Sensor Instruction Manual
The WLS907T is used to send an alarm to the receiver when the area surrounding
the unit reaches a low temperature. The predefined temperature points where an
alarm and restoral condition are sent are:
Alarm temperature:
6°C ± 2°C / 43°F ± 3°F
Restore temperature: 9°C ± 2°C / 48°F ± 3°F
Remove Cover
To remove the cover of the WLS907T, insert a small screwdriver into the slot on the end of the unit. Push the tab to release the cover.
Install Batteries
Use care when installing the batteries. Follow the guidelines below:
- Observe the correct polarity (see Figure1).
- Install the batteries positive (+) side first (see Figure 2).
Use only Eveready Alkaline Energizer batteries. Only replace low batteries with fresh ones. Always replace all three batteries at the same time.
Find a Location for the Transmitter
Locate where the transmitter is to be mounted. Perform the Module Placement Test to ensure that the selected location is in range of the wireless receiver (see receiver Installation Manual for instructions).
Mounting the WLS907T
The WLS907T should be mounted on an inside wall of the building. In addition, its position must be at least 18″ (46cm) from any outside wall, and approximately 5′ (1.5m) above the floor in a location with freely circulating air of an average temperature.
Mount the backplate of the sensor using the screws provided and replace the circuit board. The head of the screw must be below the circuit board so that the sensor is not shorted out. Use flat-headed screws only. Use wall anchors if necessary. Replace the cover carefully, so as not to damage the antenna.
NOTE: Do not touch the coils on the circuit board as this may damage the unit.
Metal will block/reflect a wireless signal. DO NOT mount the WLS907T, or any other wireless component, on or near large metal objects (e.g., metal doors, metal window blinds). Instead, find a nearby location that provides `good’ test results. Try to avoid mounting the wireless receiver in a basement or near large metal surfaces (e.g., metal ductwork) as this can reduce the range.
Location
Be sure to avoid the following locations:
- behind doors or in corners where freely circulating air is unavailable.
- where direct sunlight or radiant heat from appliances might affect control operation
- on an outside wall
- adjacent to, or in line with, conditioned air discharge grills, stairwells, or outside doors
- where its operation may be affected by steam or water pipes or warm air stacks in an adjacent partition space, or by an unheated/uncooled area behind the thermostat.
- where its operation will be affected by the supply air of an adjacent unit
WARNING – Please refer to the system Installation Manual for information on limitations regarding product use and function and information on the limitations as to liability of the manufacturer.
Tamper Switch
There is a tamper switch on the WLS907T board. Removing the cover of the
WLS907T will cause a zone tamper. See your panel Installation Manual for more
information on trouble conditions.
Enrolling a WLS907T
On the back of the WLS907T housing, there will be two serial numbers, one five digit, the other six digit. Please refer to your receiver Installation Manual for information on which serial number should be enrolled.
