Battery Checks And Maintenance - Honeywell NOTIFIER NFS2-640 Manual

NOTE: The control panel can not be put into Walk Test from an alarm condition.
To
Stop an Advanced Walk Test and return to the "Status Change Selection" screen
Advanced Walk Test directs the control panel to do the same as it does for Basic Walk Test with the following exceptions:
• Alarm and trouble messages are sent to the printer, not test messages. (These Walk Test messages can be distinguished from others at the printer
because they begin with the trouble message generated when Walk Test is entered, and end with the cleared trouble when Walk Test is exited.)
• All CBE mapped to the test input is activated except releasing functions.
Walk Test Activation Indications
FlashScan poll mode - Once the test is started:
• each intelligent addressable input device will blink its address in red, and each intelligent addressable output device will blink its address in
green. Pattern examples are given below.
• an input device activated in Basic Walk Test latches on steady green for the duration of the test.
• an output device activated in Basic Walk Test will remain active and the LED will glow steady green for:
– approximately 4 seconds for alarms
– approximately 8 seconds for troubles.
• an output device activated in Advanced Walk Test will remain active and the LED will glow steady green until the reset key is pressed.
CLIP mode - Once the test is started:
• intelligent addressable input and output devices continue to blink red as usual until activated.
• an input device activated in Basic Walk Test latches on steady red during activation. If the device is put in trouble (for instance, the detector head
is removed, then replaced), the LED will be latched on for the duration of the test.
• an output device activated during Basic Walk Test will remain active and the LED will glow steady green (if a FlashScan module) or steady red
(if a CLIP module) for:
– approximately 4 seconds for alarms
– approximately 8 seconds for troubles
• an output device activated in Advanced Walk Test will remain active and the LED will glow steady green (if a FlashScan module) or steady red
(if a CLIP module) until the reset key is pressed.
Viewing Walk Test Results
When finished with a Walk Test, view the History buffer, installed printers and CRT-2s to check the results of the Walk Test. View the History buffer
by using the Read Status function. From the SYSTEM NORMAL screen, press the
view the History buffer.

Battery Checks and Maintenance

Maintenance-free sealed lead-acid batteries used in the system do not require the addition of water or electrolyte. These batteries are charged and
maintained in a fully charged state by the main power supply's charger during normal system operation. A discharged battery typically reaches the
voltage of 27.6 VDC within 48 hours; the charge rate depends on the battery size (2.0A for 18-26AH; 5.0A-5.7A for 26AH-200AH).
Sealed lead-acid batteries must be replaced within at most 5 years from their date of manufacture. Minimal replacement battery capacity appears on
the control panel marking label. Immediately replace a leaking or damaged battery. You can get replacement batteries from the manufacturer.
WARNING: SULFURIC ACID
!
BATTERIES CONTAIN SULFURIC ACID WHICH CAN CAUSE SEVERE BURNS TO THE SKIN AND EYES AND DAMAGE TO
FABRICS.
• If a battery leaks and contact is made with the Sulfuric Acid, immediately flush skin and/or eyes with water for at least 15 minutes. Water and
household baking soda provides a good neutralizing solution for Sulfuric Acid.
• If Sulfuric Acid gets into eyes, seek immediate medical attention.
• Ensure proper handling of the battery to prevent short circuits.
• Take care to avoid accidental shorting of the leads from uninsulated work benches, tools, bracelets, rings, and coins.
WARNING: DO NOT SHORT BATTERIES
!
SHORTING THE BATTERY LEADS CAN DAMAGE THE BATTERY, EQUIPMENT, AND COULD CAUSE INJURY TO
PERSONNEL.
