DeWALT SITELOCK™ Wireless Communication Technology

Cellular Coverage and Technology

The SITELOCK portable wireless alarm system can be used virtually anywhere in the United States and Canada where cellular service is available. (If cellular service is not available, a hard-line phone back-up option is incuded for user). The Cellemetry System®: Transmits a wireless signal in less than 1 second Uses over 50 wireless carriers, include Verizon® and Cingular® Is over 2 times stronger than a hand-held cellular phone

The SITELOCK portable wireless alarm system uses wireless communication technology, so there is no need to wire in the system or install a telephone line. The center of the system is the DS100 base unit that houses receivers and transmitters which:

1. Continuously monitors all the sensors on the jobsite
   The base unit and sensors communicate using 900 MHz spread spectrum communications which send messages across a bandwidth of at least 10MHz, reducing interference and ensuring reliable communication. The base unit and sensors can communicate at a range of up to 2000 feet for wider coverage and superior reliability.
2. Communicate with the monitoring service when a sensor is activated
   The base unit uses Cellemetry® technology to communicate with the monitoring service. Cellemetry is a patented two-way wireless data network that uses the standard cellular infrastructure to transport information through the United States and Canada. Cellemetry is extremely reliable as it uses the cellular control channels and has wide range of coverage due to the high transmission power. As no phone line is required for operation, security is further enhanced.

DURING AN ALARM
If a sensor is activated, a call is immediately placed to a monitoring service. Depending on the service agreement plan selected, the monitoring service will either notify you directly via text message or e-mail, or a live operator will contact you. In certain jurisdictions the operator is authorized to contact the authorities on your behalf.
