Fuses have exposed live parts. To avoid possible electrical shock, ensure that all alarm-type
fuses have protective caps installed.
The BTRM System Alarm and Control Unit (ACU) requires no routine maintenance. To replace an ACU fuse and
protective cap, refer to cap locations as detailed in
1
Protective fuse caps (Lorain Part No. 248898700) are available for alarm-type fuses F1 through F4. If fuse
replacement becomes necessary, remove the fuse cap from the old fuse and place it on the new fuse before
installing the new fuse.

Replace a failed fuse with a 1-1/3-ampere fuse (Lorain Part No. 2486080000).
