SECTION 1

— OPERATION

1-1 INTRODUCTION

The Fire Al arm Back-u p UPS1481 provid es an except ional level of load pr ot ec t ion and
monitorin g c apabiliti es . Th e c ritical loa d is provide d with conditioned, regulated, c omputer grade
power at all times. There is co mp let e electric al is olation between th e input and o ut put voltag e of
the UPS.

When input power to th e UPS is lost, such as d uring a powe r outage, t he UPS aut omatically
draws po w er f rom its internal batte ry s upply. The c rit ic al load receives only c lean sine wav e
power. There are no dis t urbances or power interru pt ions on the output when t he UPS tra ns f ers
to battery o peration. T ransfers to and from bat t ery operation are “No Break” tra ns f ers . The
internal m aintenance-free batt eries prov ide ten (1 0) t o f if t een (15) minutes (depending upon
model) of b ac k up power. The 10 and 15 kVA mo dels have s eparate bat t ery cabinet s .

Upon restoration of input po wer, t he UPS aut omatic ally resumes normal operation. Also the
UPS immediately begins to r ec harge the b at t eries.

The Fire Alarm Back-u p UPS1 48 1 provid es com prehe nsiv e mon itori ng capa biliti es. In additio n
to the LED indicators and audible alarm, the Fire Alar m Bac k-up U PS1481 c ont ains a 160
alpha-nu m eric display and touc h pad. UPS s t at us , ev ent his t ory, and operating parameters
(such as input, output v oltage) ar e readily av ailable t o t he operator via the touch pad and
display. T he UPS 148 1 c ontains, as s t andard fe at ures , an AS/40 0 int erface, RS-232 interface,
and printer interfac e.

The Fire Al arm Back-u p UPS1481 is an on —line singl e phase UPS available in outp ut rat ings of
3, 5, 7.5, 10, 12.5 and 1 5k VA. The UP S 1481 is U . L. lis t ed under UL1 481. The Fir e Alarm Back ­up UPS1481 is available with input voltages of 120 and 240/ VAC and output voltages of
120/240/ VAC. This inf ormatio n is provided o n t he name plate located on the rear panel of the
UPS. See Appendix A for a complete listing of the U PS 1481 sp ec if ications.

1-2 BENEFITS

The Fire Al arm Back-u p UPS1481 is designed to fit t he needs of virtually all po wer conditioning
and UPS applications . I t has been spe c if ic ally designed to po wer all f orms of modern data
processing, com mu nic at ion, and process c ont rol equipment. The Fire Alarm Back-u p UPS148 1
does not re quire any d ec orating as ot her UPS products m ay when powering 1 00% electronic
loads incl uding switch—mode power supplies.

The Fire Al arm Back-u p UPS1481 protect s s ens it ive electrical equipment, s uc h as c omputer

1-3 PRODUCT FEATURES

The follo wing d escribes the major bl ocks within th e Fire A larm B ack-up UPS14 81. Ple ase refe r
to Illustration. Block Di agram for additional informat ion.

Bypass S tatic Switch — The SCR solid st at e switc h by pas ses the complete U PS and pr ov ides
utility input directly to t he load in cas e of problem with UPS. Th is switch also s upplies i nput
power to the load during the start up. It is c onnected on t he primary s ide of the o pt ional outp ut
isolation Tr ans f ormer, wh en used. Th is s w it c h maintains it ’s s t at us opposite of t hat of t he output
SCR solid s t at e switch.

Output Static Switch — This S C R solid stat e s wi t c h c onnects the output of the invert er (UPS)
to the load. I t is c onnec ted on the primary s ide of the opt ional outp ut is olation tra ns f ormer, wh en
used. This switch shut s—off in cas e of a problem or failure within the UP S and transf ers t he
load direct ly t o t he ut ilit y input via by pass st at ic s w it c h. I t main t ains it ’s s t at us opposite t o t hat of
bypass s witc h.

Power Board with IGBTs — The Power bo ard is bolted onto the IGBT block s t hat are mounted
on a heat sink. The com plet e heat s ink as s embly with IGBT and power board is re placeable as
one part. This as sembly processes ail the po we r, ie. input AC pow er c onvert ed t o DC bus,
battery power boost ed t o DC bus a nd f inally D C b us power conv ert ed to output AC power using
PWM tech nology for smooth AC Sine wave. The c omplete h eat s ink as sembly is eas ily
replaceable using o nly a s c rewdriv er, in case of a c at as t rophic failure, if requ ired. This b oard
also has the housekeeping p ower supplies and dri v er c irc uit s f or I GBTs. T his board als o
provides the landing place for all internal input, output, an d D C cables as well as it monitors the
input-out put c urrent for c ont rol and metering.

Control Board — The mic roproces s or with programma ble logic cont rollers an d on board
memory is loc at ed on this board. I t is mou nt ed on the do or and communicates, controls, and
monitors t he power bo ard via a ribbon cabl e. T his board also senses the input A C a nd s ends
the comm and to close/open the input cont ac tor, by pas s s t at ic s witc h and output static s witch.
This boar d als o s ends all the data to th e LCD display panel l oc at ed on the d oor. It als o has
modem, AS400, RS232, and R S485 output capabilities.

LCD Di s pla y Pa nel — This f ront panel prov ides all the metering data for in put , output and
battery; al arm data and UPS status f or customer use in a c onstantly c hangin g and updat ing, the
3 sets of the s c reens.

Optional Output Isolation Trans f ormer — This tran s f ormer is provided wh en t he input an d output
voltages are different , or multipl e output voltages are r equired or an isolati on at output is
required. The power t o t he primary of this tra ns f ormer is sel ec t ed either f rom UPS via o ut put
static switc h and from ut ilit y input via bypass stat ic switch. The two s t at ic s witc hes toggle on/off
as controlled by cont rol board.

Battery Char ger — Th e bat t ery charger maint ains the bat t eries at full charge. Af t er a battery
discharg e, t he c harger will aut omatically recharge the batt eries upo n res t oration of input po we r.

Battery Ban k — Th e battery b ank c onsists of s ealed, maint enance free batteries . The batteries
provide emergen c y power during power outages. The battery b ank inc ludes a br eaker for
overcurr ent protectio n and DC disconnect .

Inp ut C ont a ct or — The input contactor serves several functions. First, the input contactor
provides connections for the i nput pow er t o t he U PS. Secondly , t he c ontacto r dis c onnects t he
input line w hen an outa ge occurs so t hat ther e is no back fee ding of po we r int o t he power line.
Thirdly, t he c ontactor al lows for aut omatic UPS operati on upon a complete dis c harge of the
batteries. N o operator i nt ervention is require d w hen power to t he Lips is res t ored after a
complete battery discharge.

Control Electronics — The c ontrol elect ronics, utilizing a micro_processor, f or monit oring
provides a ll required logic signals within t he UPS and i nt erfaces with remote devices via the
interface ports such as t he AS/40 0 int erface.

1-5 The Fire Alarm Back-up UPS1481 SIZING

Each mod el of t he Fire Alar m Bac k -up UPS1481 is des igned to supply a max imum load which is
given by its k VA (1000’s of v olt -amperes) and K W rat ing. It is v ery imp ort ant that the load is
within the rat ing of the FIRE ALARM BAC K-UP ups1481 to ensure that the c onnected loads will
be properly s upporte d.

Volt - ampe res (VA) are th e number of c urrent in a m ps a device d raws multiplied by the nominal
voltage supplied to the device. T he total kVA of all the loads to be c onnecte d t o t he Fire Alar m
Back-up U PS1481 is simply the sum of the k VA requirements of each devic e.

Each electrical devic e t o be po wer ed by the Fir e Alarm Back -up UPS1481 sho uld have a
specification sheet at t ached to it which specifies the am ount of pow er it requires. I n addition,
this inform at ion shoul d als o be liste d in t he manua l s upplied with each piec e of equipm ent . T he
device’s nameplate s hould list t he electrical requirement s of t he device in so m e or all of the
following unit s : nominal volt age, current, VA o r k VA, and wat t s or KW. If VA or k VA is not give n,
then multiply t he nomin al input voltage by the c urrent shown on the nameplate. Add up the kVA
require me nt s of each devic e t o be powered by the Fir e Alarm Back -up UPS1 481.
