There are some situations where placing a phone call to notify an emergency response team is just not fast or reliable enough. What is needed is an emergency notification system that just requires a simple press of a button to notify everyone that needs to know.
A chemical manufacturing facility would be a good example of a need for this type of a system. If a chemical spill occurs, there is no time to make several phone calls. Assistance from multiple people is needed immediately.
At IntercomsOnline.com you can find the MURS Indoor Customer Service Callbox that can be used as a panic button that when pressed sends a recorded message to two-way radios, base-station intercoms, or to a 
wireless or wired public address system. You can record whatever message you want, or you could simply record a siren sound that plays when the button is pressed. If you have multiple areas where you need a panic button, then you’ll want to make sure you can distinguish between the recordings so you know where to send help.
If you don’t already have a PA system, then the MURS Wireless PA System can receive calls from the callbox and you won’t have to run expensive cabling to install it. If you already have a wired intercom, then the MURS Commercial Intercom can also receive calls, plus it has an audio output that you could run into your existing wired PA system.
