“WES” Wireless Evacuation System

System Overview: WES is designed specifically for temporary use during construction and alteration projects. With that type of environment in mind the capabilities of the system are to be flexible to meet the ever-changing needs of a building in development. Operating as a flooded mesh network, each device is both a transmitter and receiver to help build connectivity and create multiple paths of communicating to the systems base station. WES is FCC approved in the U.S. to operate on the 916 MHz frequency and its wireless range capability is roughly 1000’ from device to device in a built environment when needed and up to 3000’ clear line of sight. Creating a unique self-sustained encrypted network, each system is 100% self-reliant and entirely wireless thanks to the use of robust alkaline batteries, giving a 3-year minimum battery life in each device.

Devices: WES is made up of 5 basic devices. A “Base Station” which will be the unit all other devices on the system will communicate back to and also serve as a point of control to perform site tests and create alarm logs. - A “Call Point” unit which is both a horn strobe notification device as well as a manual push button station to alert the site of a system wide alarm and is also fitted with a medical emergency button that will report a MED signal back to the base station unit for medical response to that location, not a sitewide alarm. A “Heat Detector” unit equipped with a rate of rise detector head to detect a rise in temperature and alert the system of a site wide alarm in the event of a fire. A “Dust Proof Smoke Detector” that will operate in a dusty construction environment without false alarms. This unit will send a dirty detector head signal back to the base station when cleaning is needed to prevent false alarms. - Lastly an “Interface” unit that is fitted with dry contacts to give the WES system ability to connect and monitor existing permanent systems such as fire alarms, turn styles, elevator recall, standpipe monitoring or connecting to an auto dialer for off-site monitoring of the entire system.

Each wireless device is equipped with a tamper switch in three locations. One tamper switch on the back of the enclosure to report when removed from its location, a second on the inside of the enclosure to report when its cover is removed and the third tamper switch is located in the device components (horn strobe & detectors) to report when a device is removed/ tampered with. These protective measures help keep the system safe during deployment.

WES poles twice a day, once every twelve hours to ensure each device set up on the system is reporting back and still connected. If a device is out of range it will report a low signal on that device address. If a device has a low battery it will send back a low battery signal 60 days from the time the battery will die, giving time to address a new battery for that device. One system can have up to 999 devices and addressed by number in a three-digit naming convention.

System Warranty & Replacement parts: WES has a 2-year factory warranty from the manufacturer to cover any malfunctioning or not working devices. Replacement parts and batteries are available aside from the units themselves to repair any broken parts in the field or upgrade expired batteries.

WES Projects Worldwide: There has been over 100,000 individual WES devices in use worldwide throughout the past 10 years. Here are some recent projects to note:

• Javits Center Expansion Project – NYC• Coney Island Hospital Project – NYC• US Naval Academy - Annapolis, MD• Johns Hopkins University - Laurel, MD• 1803 Broadway - New York, NY• San Francisco Int. Airport - CA• Parkline Towers - Miami, FL• 2 Drydock Ave - Boston, MA• M.I.T. SoMa Site 3 – Cambridge, MA• Copperworks Condos (woodframe) – Canton, MA• Sawyers Reach Condos (woodframe) – Plymouth, MA• Pechanga Resort & Casino – Temecula, California• 160 Folsom - San Fransisco, CA• Swansea Mall Re-purpose Project - Swansea, MA• American Wire Factory Condo Development - Pawtucket, RI• Bermuda Airport project – UK – AECOM• London Underground Northern line extension – UK• Hinkley Point nuclear power plant – UK• Museum of the Future – Dubai – BAM International• Mall of the Emirates – Dubai – Interserve• Saudi Aramco – Saudi Arabia

System Uses: Being a flexible and expandable system by nature, WES is useful in many types of applications. Aside from being used as an evacuation system that is far more reliable than the traditional airhorn when needing to evacuate a project, WES also performs as a detection system for after hours as well as during and after any hot work activities. As the building expands and changes during construction phases, WES units can be added and moved around as needed within minutes not having to deal with wires and added costs of relocating.

Another application utilizing the WES interface unit is connecting a flow switch to the dry contacts to monitor the on-site standpipe. When the flow switch detects movement within the pipe the interface will send a signal to the WES base station and alert the system of the event. The Interface can also be connected to an auto-dialer to notify off site locations of a system alarm.

In the event of needing a fire watch, WES can also be deployed temporarily within the location of a disconnected permanent system while repairs are taking place.

Summary: Be a leader in construction site safety by protecting your people, assets and the entire building by deploying WES on your projects moving forward. Thank you for your time and consideration.
