6. Verify that the voltage is within allowable tolerances.
4-3.4 Walk Test
The FenwalNET 2000 System provides a one person Walk Test function. This allows the service person to enable a group of devices for Walk Test, then proceed through the installation activating the specified devices.
The system will respond to each activation with a short burst of the programmed signal circuit. The related sig-nal circuit will only be pulsed if it has been configured for the Walk Test feature when defining it in the FCS software.
During the system installation/configuration operation, the installer would need to enable each signal circuit installed in the system for Walk Test, if desired. The systems signal outputs default to Walk Test disabled.
When Walk Test is activated and carried out, the Sys-tem enters each activation with a time and date stamp.
The operator can then print out all Walk Test results for review.
The Walk Test feature can be deactivated two ways: (1) the service person can deactivate it through the user menus or (2) the Walk Test function will time out after 10 minutes of non-activation ensuring that the System will be back in response mode.
Note: When the Walk Test is active, the panel will an-nunciate a trouble condition.
4-3.4.1 WALK TESTING DETECTORS
Place the system in Walk Test as described in Paragraph 4-3.4.2. To place a detector into alarm, perform the ap-plicable procedure below:
Smoke Detectors- When testing SmartOne smoke detectors, use a "punk-stick or "cotton wick" to gen-erate smoke. Apply smoke to the detector for a mini-mum of 10 seconds. When a sufficient amount of smoke has entered the device, the control panel will respond with an alarm indication. The status LED of the detector will flash at a two second rate during the alarm period. Use of aerosol smoke simulation product may be used if it is acceptable to the Au-thority having Jurisdiction and if the product is used as directed in the instructions.
Heat Detectors- When testing SmartOne heat de-tectors, use of a low powered heat gun is accept-able. Heat the Detector for a minimum of ten seconds. When a sufficient amount of heat has been detected by the Detector, the control panel will re-spond with an alarm indication. The status LED of the Detector will flash at a two second rate during the alarm period. Take caution during the heating of the Detector to avoid over-heating the plastic hous-ing. Maintain a minimum of one foot between the Detector and the heat gun nozzle. Use of open flame devices are not recommended as discoloration of the plastic housing is likely and this is a potentially haz-ardous practice.
4-3.4.2 WALK TEST PROCEDURE
The step-by-step procedure to perform the Walk Test follows:
Note: If using an AIM configured as a latching device (using LaserNET software), do not include the AIM in the Walk Tests range of devices to be tested. If the AIM is configured to be latching, and the Walk Test is disabled, an alarm will be annunciated on the panel and all outputs asso-ciated with the input will be activated.
To use an AIM in the Walk Test, it must be con-figured as non-latching. When configuring the AIM (using LaserNET), select non-latching op-eration. This will allow the AIM to be defined in the range of devices to be tested and, once the Walk Test is disabled, will not create an alarm on the panel or activate the associated outputs.
1. Access the FenwalNET 2000 System's menus by:
a. Press the 0 (zero) key. Verify that the display reads:
PLEASE ENTER PASSWORD b. Type in the Level 1 or Level 2 password.

4-3.5 Alarm Simulation Test (AST)
The FenwalNET 2000 System provides a feature which allows the System's installer/inspector to verify the ac-tual output operation in relation to the input(s) which are programmed to activate the output of interest. The service person would enable the AST function for a par-ticular input and the system would operate the output(s) as it is programmed in the Event Output Control pro-gram. The system will respond with an alarm condition when the AST feature is enabled. The user would have to disable the AST when output operation has been veri-fied.
WARNING
!
Any outputs which are controlling critical processes or agent releasing should be physically disconnected from the process or agent container to avoid unwanted shutdowns and/or agent releases. When the AST function is enabled the pre- programmed outputs for the activated input(s) will activate.

4-4 DISARMING AND REARMING
RELEASE CIRCUITS
The disarming and rearming procedures which follow must be performed when testing the FenwalNET 2000 System. Prior to proceeding, ensure the notes below from NFPA 72 Chapter 7 are understood.
Note: IMPORTANT
1. "Testing personnel shall be familiar with the specific arrangement and operation of the sup-pression system(s) and releasing function(s) and cognizant of the hazards associated with inad-vertent system discharge."
2. "Occupant notification shall be required when-ever a fire alarm system configured for releasing service is being serviced or tested."
3. "Discharge testing of suppression systems shall not be required by this code. Suppression systems shall be secured from inadvertent ac-tuation, including disconnection of releasing so-lenoids/electric actuators, closing of valves, other actions, or combinations thereof, as appropri-ate for the specific system, for the duration of the fire system testing."
4. "Testing shall include verification that the re-leasing circuits and components energized or ac-tuated by the fire alarm system are electrically supervised and operate as intended on alarm."
5. "Suppression systems and releasing compo-nents shall be returned to their normal condi-tion upon complecondi-tion of system testing."
4-4.1 Disarming Release Circuits
Perform the following step-by-step procedure prior to system testing.
1. Isolate all agent release circuits using the system menu (refer to Paragraph 2-5.4.1).
WARNING
!
Use safety precautions when removing solenoids and connections from initiators (i.e.
use the shorting cap when the initiators are disconnected) to prevent unwanted discharge or activation.
2. Physically remove the solenoids or, in case of initia-tors, remove the connector at the storage containers.
WARNING
!
The suppression system is fully disarmed from all automatic activation and, in some cases, all manual activation.
3. The system can now be tested without the risk of an inadvertent release of agent.
Note: A 220 ohm (5W min.) resistor should be placed across the releasing circuit to simulate the re-leasing output device. An incandescent light may also be used in series with a 220 ohm (5W min.) resistor to show activation and simulation of the releasing output.
CAUTION
!
At no time should a lower resistance value than specified in the previous note be used.
Never hard short the releasing output to simulate the circuit. Failure to use the minimum resistance specified will result in damage to the releasing circuit.
4-4.2 Arming Release Circuits
Perform the following step-by-step procedure upon completion of System testing.
1. Verify that all solenoids or initiators are disconnected from storage containers.
2. Isolate all agent release circuits using the system menu (refer to Paragraph 2-5.4.1).
3. Reconnect the solenoids or initiators at the storage containers.
4. Ensure the System is free of any alarms to prevent unwanted discharge or activation.
5. De-isolate agent release circuit(s).
6. The System is now in full operation in accordance with System programming.
4-5 POWER-DOWN SYSTEM
4-5.1 Power-Down Procedure
The step-by-step procedure to power-down the System follows:
1. Ensure that the panel does not have any active alarms to prevent unwanted discharge or activation.
