panels to two 12V, 38 Ah batteries in an external
metal box. See Figure 18.
The battery must be a VRLA (valve regulated lead
acid) type and it must comply with all applicable
standards indicated in paragraph M.2.1 of standard
EN 62368-1:2014 “Requirements (safety of batteries
and their elements)”; In this case, the battery must
comply with the standards: IEC 60896-21:2004
and IEC 60896-22:2004. The battery must have an
enclosure with flammability class UL94V-1 or better.
A skilled professional must install and replace the
battery.
The control panel can detect, signal, and store in
memory the following power faults:
• Shorted 24A or 24R outputs
• Low battery
• Battery fault
• Battery disconnected
• Battery trouble LED
• Ground fault Earth LED
• Mains failure Power Supply Fault LED
The Battery fault may be signaled with a delay up
to 1 minute; see Table 5. The Mains (Amber) fault is
signaled when the programmed delay expires.

Description of the control keys
(panel)
Silence
Use the SILENCE key to restore the Silenceable
outputs to standby status. If the control panel
operates in Night Mode, Silence remains until the
programmed Night Mode Silence time expires; if
in Day Mode, Silence remains until you press the
SILENCE key again. In both modes, Silence status
cancels when the system detects a new alarm
condition.
Reset
You can only enable the Reset key at access level
L2 with a PIN as the fire panel returns to standby
status after the Alarm, Delay to Alarm, Warning and
Fault conditions stop. At the end of the Reset time,
the system reprocesses any Alarm, Delay to Alarm,
Warning or Fault signal that Reset operations did
not clear.
When Reset is running, the command keys are
inoperative.
Any FC500 repeater connected to the panel can
perform a reset of the fire panel. It is necessary to
use a PIN to access level L2 or higher.
For the Evacuate, Lamp or Buzzer Test, Investigate,
Silence Buzzer keys, see Table 4.
