Input/Output Connections

The P300M/P300MQ/P300MT has three customer use interlock inputs. A fault
condition on any of these inputs will cause the system to shut down; the fault must be
corrected before the system can be restarted.

There must be one RF detector per system. The remaining interlock inputs are
optional. The system blower and external interlock inputs in the P105A connector
must be jumpered if these inputs are not used.

NOTE: All external switches must have gold contacts or be designed for use
with logic-level signals to ensure reliable operation.

Remote Inputs

One switch is required for remote operation of an F300S/F300SQ (to control the
STANDBY/LAMP ON functions). Connections are made through the P106 connector.
Single or Master/Slave systems may be operated remotely.
