Test Test methods
Alarm input modules
(except waterflow
switch inputs)
Visual inspection Verify that the module’s green LED flashes. Ensure there are
no changes that may adversely affect equipment
performance.
Initial and Reacceptance 1. Open the circuit. Verify that the control panel displays a
trouble message that correctly identifies the module.
2. Short each side of the circuit to ground one at a time.
Verify that for each short the control panel displays a
ground fault message that correctly identifies the module.
3. Activate the module. Verify that the module’s red LED
flashes and the control panel displays an alarm message
that correctly identifies the module.
Annual Activate the module. Verify that the red LED flashes and the
control panel displays an alarm message that correctly
identifies the module.
Waterflow switch input
modules
Visual inspection Verify that the module’s green LED flashes. Ensure there are
no changes that may adversely affect equipment
performance.
Initial and Reacceptance 1. Open the circuit. Verify that the control panel displays a
trouble message that correctly identifies the module.
2. Short each side of the circuit to ground one at a time.
Verify that for each short the control panel displays a
ground fault message that correctly identifies the module.
3. Activate the module. Verify that the module’s red LED
flashes and the control panel displays an alarm message
that correctly identifies the module.
Semiannual Activate the module. Verify that the module’s red LED
and the control panel displays an alarm message that
correctly identifies the module.
Supervisory input
modules (except valve
tamper inputs)
Visual inspection Verify that the module’s green LED flashes. Ensure there are
no changes that may adversely affect equipment
performance.
Initial and Reacceptance 1. Open the circuit. Verify that the control panel displays a
trouble message that correctly identifies the module.
2. Short each side of the circuit to ground one at a time.
Verify that for each short the control panel displays a
ground fault message that correctly identifies the module.
3. Activate the module. Verify that the module’s red LED
flashes and the control panel displays a supervisory
message that correctly identifies the module.
Quarterly Activate the module. Verify that the module’s red LED
and the control panel displays a supervisory message that
correctly identifies the module.
Valve tamper input
modules
Visual inspection Verify that the module’s green LED flashes. Ensure there are
no changes that may adversely affect equipment
performance.
