Battery Checks
Maintenance-free sealed lead-acid batteries do not require the addition of water or electrolyte. They are charged
and are maintained in a fully charged state by the main power supply's float charger during normal system
operation. A discharged battery will charge at 0.75 amps (typically) and obtain its float voltage of 27.6 volts within
48 hours.
Replace any battery that is leaking or damaged. Replacement batteries may be obtained from Fire-Lite Alarms,
Inc. Minimal replacement battery capacity is indicated on the control panel marking label. To check battery and
system, Refer to Section "Operational Checks" above.
Caution!
Batteries contain Sulfuric Acid which can cause severe burns to the skin and eyes and damage to fabrics.
In the event a battery leaks and contact is made with the Sulfuric Acid, immediately flush skin and/or eyes
with water for at least 15 minutes. For eyes, seek immediate medical attention. A good neutralizing
solution for Sulfuric Acid is water and household baking soda. Care should be taken to insure proper
handling of the battery to prevent short-circuiting. Accidental shorting of the leads from uninsulated
work benches, tools, bracelets, rings, and coins should be avoided. Shorting the battery leads can
damage the battery, equipment, and could cause injury to personnel.
Walk Test
In order to execute Walk Test from the control panel, the PKB Programming Key must be inserted into the CPU.
Enter the Walk Test password (123-1233). The PASSWORD ACCEPTED LED will light and the WALK TEST LED
will flash. Activate an initiating device and all output circuits that are programmed as silenceable will activate for
approximately four seconds. If a device on the same initiating device circuit is activated more than once, the
outputs will activate for one second. This alternate timing scheme enables the tester to determine if devices
intended to be installed on a certain initiating circuit are in fact on that circuit. Once an initiating circuit has been
activated, its red LED will flash. All of the red LEDs on the initiating circuit modules will illuminate. The green LEDs
on all Notification Appliance Circuits that are silenceable will illuminate.
Testing Initiating Circuits for Trouble
Inducing a trouble into an initiating circuit will activate all output circuits that are programmed as silenceable. The
outputs will remain activated until the trouble is cleared. After a circuit is tested for trouble, the yellow LED for that
circuit will flash.
Testing Notification Appliance Circuits for Trouble
Inducing a trouble into a notification circuit will activate the particular circuit and pulse the circuit at one second
on/off rate until the trouble is cleared.
Exiting Walk Test
To exit Walk Test, remove the programming key.
NOTE: Fire protection capabilities are removed during walk-test.
