PS-6

Description

The Wheelock Series PS-6 and PS-8 are 24VDC, filtered and

regulated, supervised remote power supply/battery chargers are

used for supervision and expanded power driving capability of Fire

Alarm Notification Appliance Circuits. The PS-6 provides 6 amps of

power distributed across 4 outputs, while the PS-8 provides 8 Amps

across 4 output. In addition the PS-8 provides additional room in

the chassis for accessories like an Addressable Control Module, with

mounting studs.

The PS-6 and PS-8 Power Supplies are UL Listed under UL

Standard 864, 9th Edition to be used with any 24 volt Listed

Regulated notification appliances. They include the capability

to synchronize Wheelock strobes and horns and to silence the

horn signal when horn/strobes are operating on two wires.

Approvals

• Approvals Include: UL Standard 864, 1481, California State

Fire Marshal (CSFM), Factory Mutual (FM)

• Compliant with NFPA 72

The Power Supplies may be connected to any 12V or 24V (FWR or

DC) Fire Alarm Control Panel (FACP) by using a Notiﬁcation Appliance

Circuit (NAC) or a “Dry Contact”. Primary applications include NAC

expansion (supports ADA requirements) and auxiliary power to

support system accessories. This unit provides ﬁltered and regulated

24VDC, up to four (4) Class “B”, two (2) Class “A”, or two (2) Class

“B” and one (1) Class “A” Notification Appliance Circuits. With the

optional plug-in PS-EXP module the unit supports (8) Class “B” or

(4) Class “A” Notification Appliance Circuits. Additionally, an auxiliary

power output of 2.5 Amps (disconnected upon AC power loss or an

alarm condition) or up to 0.240 A of constant power on the PS-8 and

0.075 A of constant power on the PS-6.

Inputs

• 120VAC, 50/60Hz, 4.25 Amps (PS-6/8) and 5.32 Amps

(PS-8) Operating Power in Alarm

• 240VAC, 60Hz, 2.42 Amps (PS-6E and 3.22 Amps (PS-8E) ‘

Operating Power in Alarm

• 24VDC Battery Backup Connection

• Two (2), 12V or 24V NAC Initiating Circuits (8-33V at 5mA)

FWR or DC

The Wheelock Power Supplies can accommodate 7 or 12 AH batteries

inside its lockable chassis. Using an external battery cabinet it can

charge up to 33 AH batteries (pending UL testing). Two FACP NAC

circuits or two “Dry” contact initiating circuits can be connected to the

inputs. These inputs can then be directed to control supervision and

power delivery to any combination of the four (4) outputs. Each output

is rated at 3.0 Amps (Class “B”) or (Class “A”) and can be programmed

to generate a steady or Code 3 Temporal Horn sound and a strobe

output under alarm condition. Total load for the PS-6 and PS-8 NAC

circuits must not exceed the power supplies rated output.

• Two (2) “Dry”Contact initiating Circuits

• Accepts two (2) Class “A”or two (2) Class “B”circuit inputs

• Built in battery charger for sealed lead acid or gel type

batteries

Outputs

• NAC outputs are 24VDC, 3.0 Amps each, power limited

• 8 Amps on PS-8 and 6 Amps on the PS-6 total alarm current

The Power Suppliesunder non-alarm condition provides independent

supervision for Class “A” and Class “B” FACP NAC circuits. In the

event of circuit trouble, the FACP will be notiﬁed via the POWERPATH

steered input (IN1 or IN2). In addition there are two sets of trouble

reporting terminals, one used for AC power loss reporting and the

other for all troubles. The AC power loss reporting, on the common

trouble terminals and on IN1 or IN2, can be delayed for either 30

seconds or 170 minutes. The AC power loss terminals will always

report the trouble within 1 second after loss of AC power.

POWERPATH™ Operating Modes (refer to Installation Manual):

Normal Mode: Provides constant 24 VDC output upon initiation by a voltage to input IN1 or IN2 or by a contact opening

on DRY1 or DRY2. The unit returns to standby mode when the input is deactivated.

Wheelock Sync Mode: Provides signals for synchronization of patented Wheelock audible and strobe notification

appliances. Audibles can also be silenced in this mode while the strobes continue to ﬂash.

In>Out Sync Mode: Accepts a synchronization signal on the input to provide a coded output or synchronized output. This signal

may come from a FACP, another POWERPATH or aWheelock DSM synchronization module. Caution: Do not use strobes on coded

output circuits.

True Input Follower Mode: Accepts a coded signal on the input to provide a coded output with the same timing as the

input. The signal may come from a FACP, another POWERPATH or other coded source. Caution: Do not use strobes

on coded output circuits.

Temporal Mode: Codes the output voltage in a code-3 temporal pattern to drive audible appliances such as horns,

bells or chimes. Caution: Do not use strobes on coded output circuits.
