Access Controls Careful consideration should be given, early in the planning stages, as to how the gate system will work so that appropriate equipment can be installed. For example, will the gate work in semi-automatic mode (signal to open, signal to close) or automatic mode (signal to open, gate closes automatically on a timer). Fully automatic systems provide the greatest security, but do raise issues as to how visitors will gain entry, and exit the property. Telephone access systems provide a convenient way to screen visitors on control gate operations (open, hold open, open automatically at designated times, open with valid code entered at keypad), especially when equipped with a pin hole camera. Surge protection should be installed on all telephone lines.. For the owner a hand held transmitter provides the most secure way to enter and exit through the gate. Codes transmitted by security gate transmitters can’t be ‘grabbed’ by specialized equipment used by thieves. Exiting the property can be done with a loop free-exit loop in the driveway, a keypad and code, or remote activation of gate by owner.. Another important question is how will emergency vehicles such as police, fire, and ambulance gain access. A residential fire and security alarm can be configured to automatically hold open the gate system to allow access to the property. A siren listening device that responds to the siren yelp from any emergency vehicle is a good option. Or a emergency key lock device that allows emergency responders to use a special key to lock open the gate system. - Gated Communities - Operators - Access Controls - Safety Devices
