gun, to each thermostat. Each time, the pin at the base of the Electric Actuator should extend with an audible
‘click’. Use the back of a writing pen (or similar) to manually push the pin back up into the Electric Actuator
after firing. Reset the Amerex SR-X Releasing Panel upon completion of testing. Inspect the status of the
two ECH actuating pins as shown below prior to installing nitrogen cylinders.

TESTING THE MANUAL PULL STATION OF THE ELECTRIC CONTROL HEAD (ECH) SYSTEM
After the Detection Network has been tested and BEFORE RE-INSTALLING THE ELECTRIC ACTUATOR
AND NITROGEN ACTUATION CYLINDERS, the Manual Pull Station must be tested: Pull the FIRE handle
on the Manual Electric Pull Station. The pin of the Electric Actuator must extend at this time with an audible
‘click’. Use the back of a writing pen (or similar object) to manually push the pin back up into the Electric
Actuator after firing. Reset the Amerex SR-X Releasing Panel upon completion of testing. Re-install the
Electric Actuator onto the ECH.
Warning : Failure to reset the Electric Actuator prior to re-installation will result in system actuation.
