1 General

1.1 Validity

The following documentation is valid for the SecuriFire B6-PSU Power Supply Unit with edition EG072950--.

1.2 General

The B6-PSU (Power Supply Unit) is fitted in the map case of every SecuriFire 1000/2000 on the right and next to the main

control unit.

1.3 Compatibility notice

Notice

The B6-PSU is included in the basic configuration of each SecuriFire 1000/2000 and is supported regardless of

the SecuriFire software.

2 Design and function

The B6-PSU Power Supply Unit is an internal 4 A power sup-

ply unit, and together with the B6-

BCU main control unit it

forms the basis of the B6 hardware platform.

The B6-PSU supplies the required output voltage of 3.3 V, 5

and 27 V to each SecuriFire

1000/2000. In the event of mains

failure, the standards-

compliant battery buffered DC voltage

for the SCP and peripheral devices must be ensured. This is

accomplished by connecting two (or four) batteries of a type

which has been tested by VdS and approved by Securiton

AG.

The batteries are connected on the bottom side of the B6-PSU

with a 2

-pin terminal and monitored.

Fig. 1 B6-PSU

2.1 Overview

The B6-PSU

has a map case made of galvanised sheet steel.

It is always fitted next to the B6-

BCU main control unit on the

right and connected via a 64-pin male connector.

On the underside of the power supply unit is a 10-pin plug-

screw terminal to which external consumers can be connected

via five separately fused outputs.

Two batteries (15...18

Ah) can be connected to the power

supply unit to supply emergency power.

2.3 Batteries

Power can be supplied to the internal and external consumers either from the mains or internal batteries; this guarantees

power supply to the system from two independent sources of energy. If there is a mains voltage or mains power supply fail-

ure, the internal batteries automatically supply the system with power.

2.4 Connection

One battery pair (15...18 Ah) is connected to the B6-PSU by default in a SecuriFire 1000/2000.

2.5 Battery charge

The batteries are charged by the mains supply, whereby the temperature-regulated charging voltage is between 26.3 V (at

50°C) and 28.3 V (at 0°C).

This guarantees a battery charge of 80% of full capacity within 24 hours.

Notice

The temperature sensor integrated in the B6-PSU Power Supply Unit monitors the ambient temperature of the

SecuriFire SCP.

2.6 Battery test

The batteries are subjected to a battery test every 10 to 15 min. for 10 s.

If the batteries indicate a fault (e.g. cell short-circuit or battery short-circuit), the system voltage is automatically disconnected

from the batteries by the integrated protection circuit. When this happens, only the battery charging current and not the sys-

tem supply current is interrupted; this guarantees the uninterruptible power supply of the system even if the batteries are

faulty.

The criterion for disablement of the charging current is a battery undervoltage of approx. 18 V. When the battery charging

branch is disabled, the system voltage is regulated to the nominal 29 V.

Should the mains supply fail and thereby the associated transition to battery supply, monitoring the batteries to protect them

against low charge is extremely important. For longer mains failures, the consumers are disabled when the battery voltage is

typically 19.6 V.

Re-enablement is possible only when the mains supply is restored or by pressing the On/Off switch; in the latter case, the bat-

tery voltage when under load must also be > typically 23.5 V.

Power requirement

B6-PSU Power Supply Unit, Technical Description, T 811 039 en a 13 / 18

3 Power requirement

Notice

•

In the event of a power failure, the fire alarm control panel is powered by batteries. Depending on the con-

figuration and connected peripheral devices (units, detectors, sirens, etc.), it is important to ensure that the

batteries have sufficient capacity to operate the fire alarm control panel for the specified time (e.g. according

to a standard or directive).

•

Moreover, the consumer current has to be dimensioned so that batteries which have become empty can be

charged to 80% of their capacity within 24 hours.

3.1 Typical power consumption values for B6-PSU Power Supply Unit

The power consumption of the board must also be taken into consideration when calculating the power requirement:

Type Designation Quiescent current Alarm current

B6-PSU

SecuriFire unit 34 mA 34 mA

3.2 Power requirement calculation

For the power requirement calculation there is a power calculation tool in which the battery types in use and the necessary

bridging time (according to local standards and directives) are entered.

3.3 Battery current measurement

After the system has been successfully commissioned, it is necessary to perform a battery current measurement (mains fault

under full load, dropped holding magnet, display lighting off, printer at standstill, service PC cable disconnected from the SCP)

in order to guarantee that the battery capacity meets the requirements.

If the results of the battery current measurement (example with a 18 Ah battery pair) is not in line with the power requirement

calculation (±5%), notify your Securiton Support point immediately.

Observe the following procedure precisely:

•

During normal operation, remove the mains plug of the B6-PSUB6-PSU power supply unit of the SecuriFire 1000/2000:

there must be no pending alarms or disablements; the batteries must be connected and charged.

•

Mains fault is displayed (after a delay time): the batteries now supply power to the SCP without exception.

•

Switch on the measuring instrument (multimeter, voltmeter) and set to the “DC” measurement range. The expected meas-

urement value is approx. 10-2000 mV DC.

•

Attach the battery power cable (art. no. FG81720) on the B6-PSU to the battery power connector and connect to the

measuring instrument.

•

Read and note the measurement value (= quiescent current) on the measuring instrument.

•

Trigger armed alarm for all (if possible) activated fire incident controls supplied by the SCP.

•

Read and note the measurement value (= alarm current) on the measuring instrument.

•

Convert measurement value: measurement value [mV] / 50 = battery current [A].

•

The calculation of the available minimum charging current must be performed using the formula C

(nominal battery capacity)

x 0.05.

For 2x 12 V / 18 Ah batteries, this corresponds to a charging current of 0.9 A; this results in a maximum battery current of

3.1 A (= 155 mV).

•

Guaranteed from 18 Ah if the quiescent current is less than 0.23 A (= 11.5 mV).

•

When using other battery capacities or bridging times, the following calculation must be performed:

(quiescent current x quiescent bridging time) + (alarm current x alarm time) < effective battery capacity.
