Installation and Maintenance Instructions

An Overview of the Model PS600

The Model PS600 Power Supply is a nominal 12 Vdc or 24 Vdc
supervised power supply that provides primary power and/or
standby power to various devices in a SelecTone system while
maintaining the charge level of an integral 24 volt battery package.
The battery package automatically supplies power during power
outages. When power is restored, the supply recharges the batteries.

The PS600 is housed in an enclosure designed for permanent
mounting on a wall or another substantial vertical surface. An
optional key-lock door is supplied for the front door of the cabinet,
the lock is provided to discourage unauthorized access. The unit is
intended for indoor use only.

Certications

This power supply is intended for use in applications requiring
UL certication for re protection signaling and access
control. The power supply must be installed in accordance
with National Electric Codes and in accordance with NFPA 72
(protective signaling systems).

The PS600 meets these additional certications:

UL certications 1481 and 294, suited for UL certied re
alarms and control systems

NYC Department of Buildings Approved (MEA)

California State Fire Marshall Approved (CSFM)

CSA Approved (Canada)

PS600 Circuitry

The power supply converts 120 Vac at 50/60 Hz or 240 Vac
at 50/60 Hz into a fully regulated 12 Vdc or 24 Vdc output.
The unit has a 6 A capacity, and the output is protected by a
poly switch (PTC). The battery is also protected by a 10 A
fuse. The PS600 is equipped with thermal and short-circuit
protection with auto reset.

Selectone Model PS600

Installation and Maintenance Instructions

The power-supply printed circuit board contains circuitry that
provides dc operating voltage to units in a SelecTone system
and maintains a charge level on the batteries when ac power
is available. It also includes logic circuitry that controls the ac
power LED, dc power LED and transfer of battery connection
to the output during an ac power outage. The power supply has
green and red LED indicators mounted on the printed circuit
board inside the PS600.

The circuitry is divided into two sections: the dc output circuits
and the charger/logic circuits. The output circuits supply dc
operating voltage to the load when ac voltage is available.
The charger/logic circuits control the charging of the battery
package and the red dc power and green ac power LED
indicators. See Table 1.

Table 1 Power supply circuit board LED indicators

Red (dc) Green (ac) Description

ON ON Normal function

ON OFF Battery backup is powering output

OFF ON No dc output

OFF OFF System off, no battery

Charger/Logic Circuits Diagnostics

The charger/logic circuits consist of battery charging circuitry.
This part of the circuit also illuminates the green and red LEDs
which indicate the presence of ac and dc voltage, respectively.

Furthermore, the power-sense circuit causes the green LED to
turn off if the battery backup is powering the output, or if the
system is off and there is no battery. This circuit also causes the
red LED turn off if there is no dc output, or if the system is off
and there is no battery.

The battery terminals provide a convenient location for
checking the battery voltage with a dc voltmeter. To check
the battery voltage, connect the negative voltmeter lead to the

Installation and Maintenance Instructions

Mounting the PS600

The steel enclosure of the Model PS600 power supply is designed
for mounting on a wall or other substantial vertical surface. The
PS600 is shipped without the batteries installed. The batteries must
be installed after the unit is mounted.

When installing the PS600, do NOT use electrical conduit to
support the unit because the device weighs 13 lb fully assembled
without the batteries. When mounting the unit, be sure the
mounting surface can sustain the weight of the PS600. The method

of mounting the unit must also withstand external mechanical

stresses that may be applied to the cabinet. The cabinet has three
holes located in the rear to accommodate #10 mounting screws.

To mount the PS600:

1.

Before installing the batteries, use the power supply enclosure

as a template to mark the location of the three mounting holes
on the mounting surface.

2.

Mount the cabinet with the appropriate hardware. Make sure

that the unit is rmly secured to the mounting surface.

3.

Terminate the conduit for the 120 Vac or 240 Vac power at

one of the two knockouts located at the upper right side of the
cabinet. These knockouts are located above and to the right of
the two transformers.

4.

Terminate the conduit for the 24 Vdc or 12 Vdc output at one of

the knockouts located at top or the middle left side of the cabinet.

Installing the Batteries and Wiring the PS600

SHOCK HAZARD: To avoid electrical shock hazards, do not
connect or disconnect wires while power is applied.

CHARGE BATTERIES BEFORE USE: Batteries are shipped
partially charged. Allow at least 48 hours of charging time
before operating from batteries.

10

Selectone Model PS600

Installation and Maintenance Instructions

NOTE: For access control applications, batteries are optional.

When batteries are not used, the loss of ac will result in the loss of
output voltage.

The PS600 should be installed with the National Electrical Code
NFPA 72 and in accordance with any local regulations. Use only
18 AWG wire for all power connections (battery, dc output). Use
22 AWG to 18 AWG wire for signaling outputs (ac and low battery
supervision).

NOTE: In accordance with NFPA72, the wires to the batteries

do not have to be supervised provided that they are in conduit or
equivalent to prevent mechanical injury.

For 120 Vac or 240 Vac power Class I conductors:

Use one of the two knockouts located at the upper right side of the
cabinet near the two transformers.

For the non-power limited 24 Vdc or 12 Vdc output conductors:

Use one of the two knockouts in the top, either the middle or the
left side of the cabinet or the knockout in the middle of the left
side. Make sure that all power-limited re protective signaling
conductors are segregated from electric light, power, Class I, or
non-power limited re protective signaling conductors by more
than 0.25 inch inside the power supply cabinet.

Determining the Total Ampere-Hour Capacity

The PS600 battery consists of two 12-volt, sealed lead-acid
batteries connected in series. These batteries supply emergency
power to units in a SelecTone system or other devices during
electrical power failures. The power supply includes a built-in
charger for the batteries.

The length of time that the batteries can supply power depends
upon the amount of current drawn by the loads. In normal re
alarm systems, the two time frames are used: twenty-four hours
on standby, followed by ve minutes of alarm, or sixty hours on
standby, followed by ve minutes of alarm.

Selectone Model PS600

11

Installation and Maintenance Instructions

The power supply must have enough capacity to properly operate
the external equipment. Calculate the standby current and the
twenty-four discharge rate on standby or the standby current and the
sixty hour discharge rate on standby. Determine the total ampere­hour capacity necessary as described in the following example:

Discharge Rate: 24 hours

Standby current: 0.200 A, 24 Vdc

Five minutes Alarm Current: 6 A, 24 Vdc

Useful Battery Capacity: 85 percent

Capacity needed = (discharge rate [hours] x standby current
[amps]) + (alarm hours [hours] x alarm current [amperage])/useful
battery capacity

Capacity Required: ([24 x 0.200] + [5/60 x 6])/0.85

= ( 4.80 + 0.5)/0.85

= 5.30/0.85

= 6.23 Ah

In this example, a 24 Vdc, 6 A power supply with 24 V, 12 Ah
battery can operate the signaling device.

Determining the Maximum Load Discharge

Determining the maximum load discharge current from a specic
battery size over a specic amount of time can be tricky. Batteries
are rated at maximum efciency over a 20 hour discharge period.
Therefore, a 20 Ah battery will provide 1 A over a 20 hour period.

However, calculating discharge time for other discharge currents
is not as easy as division or multiplication. A 20 Ah battery will
supply 1 A for 20 hours. However, it will not provide 2 A for 10
hours, but rather 1.8 A for 10 hours, which is equivalent to 18 Ah.
