BATTERY

As a function of the 5140XM control, battery voltage is montored once every 60

SUPERVISION

seconds. Under normal Wndifions the battery votiage should be approximately

13.65VDC. If battery voltage drops below approx. 11.5 volts, a low battery

message is sent to the central station and annunciated on the local mn$eis.

Battery lead supervision can be tested from the panel. The recomme}.>

procedure is to disconnect the battery harness from the 5140XM at the tab

facations found on the left side of the 5140XM. Within 60 seconds a low battery

signal will be sensed and the control bagina communicating the information to the

central station.

BACK-UP POWER

The panel provides a circuit for float charging a 12 VDC, 12 AH rein/34.4 AH max

CALCULATIONS

lead acid (gel cell) back-up battery. The. float charging voltage is set to approx.

13.7 VDC. UL requires that the battery’s capacity be sized to provide 24 hours of

standby time for fire or for comMnaton fhe/burglary appkcations. This can be

*ne as follows:

Rll out the POLLING LOOP CURRENT DRAW WORKSHEET, shown on nexf

page, to determine the total current drawn from the poifing loop (skip this step

if ~lling faop not used).

Hll out the TOTAL STANDBY/AMRM LOAD WORKSHEET, shown on next

page, to determine the total standby and alarm load drawn from the pane~s

pwer supply.

Hll out the BATTERY CAPACIW CALCULATION WORKSHEET, sbwn on

next Daae. to determine the reauired caDacffv for the backuo batferv. Select

one of fie batteries given in the BA~ERY SELECTION TABLE, sfiown on

the nefl page.

POWER-UP Connect all zone, polling loop, mnsole, auxifiary device and bell circuit wiring.

PROCEDURE Wire and plug-in the 1451 transformer. After a few semnds the console’s green

POWER indicator should tight. If not, check that the 1451 transformer is

supplying proper voffage to the panel (about 17-19.5VAC when the power tine

voitaae is 11O-120VAC).

Mea~ure the voffage across the “+” and “-” battery teminals on the main PCP ‘o

check that there is proper float charging voltage (13.5-13.8VDC). If not,\_,2

auxiliary power terminals may have been loaded in excess of their ratings.

Connect the back-up battery(s) using the batte~ harness supplied as shown

below. The panel performs a brief teat every 60 seconds to determine if there is a

battery connected, and performs an exended test eve~ 24 hours to check the

battery’s condiion, and provides a “SYSTEM LOBA~ indication when it finds

that the batiev vokage is bw (less than approx. 11 .5VDC; see the TESTING THE

SYSTEM section for mre information). Batteries which are low in vokage may

take up to 46 burs to fully recharge.

The consoles will display the installer’s message (default message is

“DISARMED-READY TO ARM”) if all zones are intact and there are no system

problems. If Mt diWlayed, correct zone and system problems as needed.
