Wiring the LR5 TempGuard:
The LR5 Tempguard is supplied with a green 7-contact plug to make wiring easy. A
plug legend is attached to the back plate of the control. It is summarized below:
Pin 1 AC Line (polarity does not matter)
Pin 2 AC Line (polarity does not matter)
Pin 3 Door Alarm (polarity does not matter)
Pin 4 Door Alarm (polarity does not matter)
Pin 5 Remote alarm (normally open contact)
Pin 6 Remote alarm (common)
Pin 7 Remote alarm (normally closed contact)
AC Line - Power wired into AC line of the system.
Door alarm - The door alarm circuit on the LR5 detects an open or closed circuit.
An open circuit indicates that a door has been opened while a closed circuit
indicates that all doors are closed. The circuit should be wired in series through
switches attached at each door.
Remote Alarm - A relay is provided on the LR5 to signal an error condition.
Continuity exists between pins 6 & 7 in a normal condition. An error condition
provides continuity between pins 5 & 6.
