1.5 ESD and Alarm Output Connector
There is a removable screw terminal connector plugged into the main circuit board of the P3F master
station for the connection of ESD hard-wired inputs and for connection to the internal alarm relay
contacts, when required. (On most systems these terminals will not be used; in which case a hard-
wired link between pins 4 and 5 should be added.)
Note that the relay is shown in the ‘Alarm Active’ or ‘power removed’ position.
1.6 Current Loop Connections
A removable screw terminal connector is located in the bottom of the Current Loop Module for the
connection of the Pakscan IIE current loop to the field mounted actuators.
