Appendix C
Battery backup is a requirement for the
MXL-IQ. To determine the size battery you
must use, follow the procedures listed
below. The MXL-IQ can charge a battery
of up to 55 amp hours. A battery size
calculation form is also provided.
1. Record all the modules required in the
form on the following page.
2. Calculate each row across and place
the total in the right column: Total
Standby 24 VDC Module Current
3. Total the right-hand column and record
it at the bottom of the form opposite
Total System Current.
4. For NFPA 72 Local, 72 Proprietary,
and UL 1076 systems multiply the total
system current by 24 and record it at
that Total AH location.
or
For NFPA 72 Municipal Tie and 72
Remote Station systems multiply the
total system current by 60 and record it
at that Total AH location.
or
For FM Approved Deluge/PreAction
systems multiply the total system
current by 90 and record it at that Total
AH location.
MXL-IQ Battery Calculations
5. Multiply the AH Total by 1.3 to obtain
the final battery amp hour capacity and
record it opposite Battery Size.
Three battery models are UL listed for use
with the MXL-IQ:
BP-61—24V, 15 AH
BTX-1—a set of 12V, 31 AH
BTX-2—a set of 12V, 55 AH, 65 AH,
or 75 AH*
*Although larger batteries may be used,
as noted, the 55 AH capacity must be
used for determining battery require-
ments.
Select the battery that meets or exceeds
the final calculated battery amp hour rating.
Use an external battery box with the BTX-2
model.
