Universal Transmitter
The WLS905 and WLS907 Universal Transmitters are general purpose
detection devices that may be used as door or window contacts. Universal
Transmitters feature their own built-in contacts, and they may also be wired
with external contacts. Each Universal Transmitter requires:
• Three AAA Batteries
Universal Transmitter Operating Temperature Range:
• 0°C to 50°C (32°F to 122°F)
Smoke Detectors
The WLS906 Smoke Detectors are photoelectric smoke detectors designed
for either ceiling or wall mounting. Refer to Appendix A Guidelines for
Locating Smoke Detectors. Each Smoke Detector requires:
• Six AA Batteries
Smoke Detector Operating Temperature Range:
• 0°C to 50°C (32°F to 122°F)
Batteries
The WLS900 System is designed to use Eveready Alkaline Energizer Batteries.
Do not use other brands of batteries with the WLS900 System. Using brands other than the
Eveready Alkaline Energizer will void UL and ULC approvals, and may affect the system’s
operation.
AC Adaptors
The AC adaptors supplied for the Controller and Sounder are not interchangeable. The adaptors are clearly
labelled; ensure the Controller Adaptor is used with the Controller, and the Sounder Adaptor is used with the
Sounder.
