3 SYSTEM INITIALIZATION
3.1 GENERAL
To facilitate the initial setup of the SYSTEM 3505, the following procedures should be
performed in the order in which they appear.
3.2 ASSEMBLY
The SYSTEM 3505, itself, requires no assembly. Refer to the specific sections of this
manual for additional assembly requirements to connect the options supplied. The main unit
should be started prior to connecting all options. Plug in the power cord and connect to a
120/240VAC dedicated fire alarm branch circuit, labeled as such. Connect the branch circuit
to an ETL listed outlet box with duplex outlets, rigidly mounted in the bottom, per installation
requirements of the National Electrical code and any local code. System 3505 is designed to
be installed in a standard 19" equipment rack.
3.3 BATTERY INSTALLATION
The standby power for the SYSTEM 3505 may be supplied by an externally supplied 24 Volt
DC source, (i.e., batteries and charger), such as the DIGITIZ SEBB-6/24 (P/N 425403-0001).
This is to be connected after the unit is operating on the AC source.
3.4 POWER-UP
To power up a SYSTEM 3505, primary AC can be applied first, then the standby DC power
may be applied.
3.4.1 AC Power
To power-up the unit, move the AC power switch on the rear of the unit to the on
position. At this point the unit will start initializing.
3.4.2 DC Power
After AC power has been applied, connect field-supplied external batteries
and/or charger (SEBB-6/24) to the 24 volt DC input terminals.
Refer to Appendix D, SYSTEM 3505 Installation Drawing # 800321 for electrical
connections.
3.4.3 Power Transfer
If the AC power should fail for any reason, the unit will automatically transfer to
standby battery, the AC power lamp on the front panel will flash and the trouble
signal will sound. When AC power is restored, the unit will automatically
transfer to normal operation. The AC power lamp will remain ON and steady.
AC failures and restorals will be annunciated, and printed, if a power failure lasts
more than 15 seconds.
