The Guardian STC9 Infra Red Transmitter Personal Activation Device comprises of Infra Red Transmitters, battery monitor circuit with confidence LED, push button activator and attack level “retaining peg” activation method. With the pin removed the unit will transmit the call signal for up to 8 minutes before shutting down to allow the call to be reset in the event of a hostage situation.
The Guardian STC9 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 this type of lighting technology.
