it generally comes in the form of medical, law enforcement, administrative services, or fire and rescue as shown in the image on the left. There are two parts to the system. That red rectangular thing at the bottom center is called a Wireless Call Box (WCB). It works in conjunction with another device called a HelpAlert.
The Wireless Call Box or WCB is only 4" H x 2.5" W x 1.5" and can be placed anywhere It weighs only 4.4 ounces and requires no electrical connection. It is powered by a long life lithium battery that should keep it going for up to three years or more before replacement is necessary (a few bucks and a few minutes, and you are back in business when the battery needs replacing. BTW, it will let you know when it is time to change the battery.
The WCB is a digital device programmed to send a code to a companion device known as the HelpAlert. When someone pushes the button on the WCB, a digital coded signal is sent to the HelpAlert. Depending on the code, the HelpAlert will generate a voice message, such as maintenance assistance needed in area 12 or medical emergency in plant office, etc.
A centrally located HelpAlert (shown at left) can provide coverage for up to eight WCB units anywhere within a 120,000 square foot area at distances of up to 100 feet between the WCB and the central HelpAlert. The WCB can be a single push button model, as shown, or an optional model with up to four push buttons to call for EMS, LAW, ADMIN or FIRE assistance. The standard HelpAlert can operate on up to four different radio frequencies within either the VHF or UHF frequency bands. In areas where working relationships exist with participating first responder agencies, the HelpAlert can operate on different frequencies as required in the same band.
We also have models of the HelpAlert for use in the 700 and 800 MHz bands as well as compatible models for DMR (MotoTRBO) and NXDN (Kenwood) digital radio systems. We also have models that can send voice message to SouthernLINC radios as well as text messages to PC's or cell phones, or to standard VHF or UHF 2-way radios AND cell phones and PC's! Note: Cell phone models require broadband Internet connection (not supplied).
For larger facilities, we offer the EX Wireless Call Box which is capable of covering up to 120,000 square feet and a more powerful VHF or UHF AlarmAlert transmitter for broadcasting over 2-way radio systems.
