Powering Third Party Devices
The Tocsin 700 controller has been extensively third party tested to ensure electrical
safety and EMC compliance in a number of installation formats.
The requirement to power gas shut off solenoid valves is common and so has been
tested. The following tables and wiring arrangement will allow a suitable solenoid to
operate correctly from the control panel.
In general third party devices should only be switched and NOT powered from the
Tocsin 700, (with the exception of beacons and sounders).
Connecting third party devices which may place unknown power demands on the Tocsin
700 can result in damage and/or unintended operation and so is NOT recommended.

overload the power supply.
