Description

The Guardian STC8 Dual Technology Personal Activation Device comprises not only of infra red transmitters, battery monitor circuit with confidence LED, push button activator and attack level retained peg activation method, but also has a radio transmitter and aerial built into the unit. The unit, once activated, sends an Infra red signal as described above, and simultaneously sends the same codes via the radio transmitter.

This dual technology provides RF back up to the infra red, or additional coverage to larger external areas such as Staff Car Parks, where it is impractical to use infra red.

The Guardian STC8 transmits on a high infra red frequency as well as the standard infra red frequency. This means it is ideal for use on sites where high frequency switched lighting has been installed, and overcomes the potential problems associated with type of lighting technology. It can also be used on older sites where the standard Guardian AIRX4 IR Receivers have been installed.

The Guardian and InterCall systems are intelligent and will only acknowledge the RF Signal, if the system has NOT detected an Infrared Signal from the same user.

When it has received an Infrared signal, it will track the activated user, cancelling alerts from past locations and only showing the current/latest location.

If the user is out of Infrared range and only RF is being detected, the system will show the last known location – this will be the location of the nearest RF Receiver which has a 50m range.
