nected.

No independent external power source or supply connection is
necessary. Power to operate the 24 Volt fire suppression system
is from the rear junction/contactor box.
Auxiliary Alarm
The fire suppression system provides an auxiliary output signal
when the system is activated. During tumble dryer installation,
you have the option to connect a separate alarm system to this
auxiliary output. Potential uses of the auxiliary output include,
but are not limited to: (1) sounds an alarm, (2) activates a build-
ing sprinkler system, (3) notifies a fire department, etc. Use of the
auxiliary output is not required for the fire suppression system to
operate, but may be used for additional protection.
The connection to the auxiliary output is made through the FS-1
and FS-2 fast-on connections inside the fire suppression control
box. Refer to Figure 5 . The relay is rated for 24 VAC, 5.2 Amp,
sealed current.
NOTE: The auxiliary output is activated during fire sup-
pression system maintenance test sequence. Consider
this fact prior to your system test every three months.
(Example: If the external system uses the auxiliary out-
put to call the fire department, inform the fire depart-
ment before and after the fire suppression system
maintenance test.)
