4.7 RBS Alarms
A dedicated 66-block provides all controller hardwired alarms. Normally-open and normally-closed contacts are available
for each of the eight possible RBS alarms. For installations with limited interior space, a 25-pair pigtail is provided rather
than the dedicated 66-block to allow the alarms to be wired directly to the main shelter alarm block.

4.8 Bonding
All of the electrical components within the NextGen CoolLinks™ controller are grounded to the back panel and this back
panel is in turn grounded to the enclosure. The outside of this enclosure should be grounded to the shelter halo with a
green 6 AWG stranded wire using a two-hole compression lug on the case and a C-tap at the halo. Two pre-drilled
bonding locations are provided on the top left hand and top right hand sides of the enclosure.
