The auxiliary output circuit is powered by feedthrough of 12/24
VDC @ 1.5 A nominal provided from external power supply.
The Circuit is disabled when the CHECKFIRE 210 System is
operating on the internal power supply.
Connections to equipment components are made by others.

Before installation remove fuse and place in a safe place.
Install power circuit using the following rules:
1. It is recommended to install power circuit directly to the
12/24 VDC nominal vehicle battery(s), if possible. This will
provide continuous power for 24 hour system protection.
2. Install 1/2 in. (13 mm) ring terminal on black jacketed
conductor, labeled “– VEH BATT” to the negative post
on battery or 12/24 VDC nominal power source.
3. Install 1/2 in. (13 mm) ring terminal on red jacketed, 3A
fused conductor, labeled “+ VEH BATT” to the positive
post on the battery or 12/24 VDC nominal power source.
do not install fuse at this time.
4. Route and secure the Power Circuit Cable following the
installation instructions under Cable Connectivity / Installa-
tion, page 5-5.
5. Do not install fuse until entire system is ready for testing
(refer to Section 6 – Operational Test and Place in
Service). when ready, install fuse following required steps
(a – e) to ensure an IP67 connection. See Figure 5-48.
a. Insert new fuse.
b. Apply entire contents of supplied Dow Corning 4
(dielectric grease) inside inline fuse holder cover.
c. Snap cover in place and press firmly together around
outer edges to properly seal.
d. wipe off excess grease on outside of inline fuse holder.
