Function/Description

TB1-1, 2 IN1+, IN1-

These terminals connect to the input voltage source (i.e. 12VDC or 24VDC

FACP). The FACP will supply a voltage from 8-33VDC at 5mA. During the alarm

condition these inputs will cause the designated outputs to drive the notification

appliances (designated outputs are set by output DIP switch banks). During

Stand-by on a FACP, a trouble condition on the designated loop will cause these

inputs to open, providing a trouble condition on the FACP. Alarm condition always

overrides trouble to drive output indicating appliances.

TB1-3, 4, RET1+, RET1-

EOLR is connected on these terminals corresponding to IN1+ and IN1-, or the

loop may be continued to other power supplies or appliances before terminating.

TB1-5, 6 CC1+, CC1-

Dry contacts are used to actuate the designated outputs. Contacts are normally

closed and actuate the power supply on contact OPEN. Designated outputs

correspond to IN1+, IN1-. NOTE: FACP NAC circuit cannot energize the power

supply by these contacts. When these terminals are not in use, a jumper must be

connected across them.

TB1-7, 8 IN2+, IN2- Same as IN1+, IN1- for corresponding terminals.

TB1-9, 10 RET2+, RET2- Same as RET1+, RET1- for corresponding terminals.

TB1-11, 12 CC2+, CC2-

Operates the same as C “Dry2” NC for corresponding terminals. When these

terminals are not in use, a jumper must be connected across them.

TB1-13, 14 S BUS IN+, IN-

Synchronizing Bus IN: Links from previous PS-8 (PS-6) “S BUS RET” to

synchronize both together. Controlled as Master or Remote by switch SW3

Position 4. Current Draw is 0.006 Amps per PS-8 (PS-6).

TB1-15, 16 S BUS RET+, RET-

Synchronizing Bus RET: Sync control output from the master PS-8 (PS-6) to

additional PS-8 (PS-6) panel “S BUS IN” terminals. Always place 10K Ohm

EOLR on the last panel. Controlled as Master or Remote by switch SW3 Position

4. Up to 40 power supplies can be connected to the PS-8 or 12 to the PS-6.

TB2-1,2 SIL+, SIL-

Audible Silence: NAC input to the master PS-8 (PS-6) from FACP. The Audible

signal is transmitted to all PS-8 (PS-6) panels within the loop. Power Limited.

TB2-3,4,5

“NO” “C” “NC”

(COMMON TROUBLE

OUTPUT)

Typically used to trigger remote alerts or other reporting appliances. Form “C”

contacts rated 24VDC at 1 Amp. NOTE: These terminals must be monitored by

the FACP for Class “A” mode.

TB2-6, 7 + AUX OUT -

This output has two modes of operation. The CP Mode is capable of 0.02 Amps

for 60 hours (PS-8 only) or 0.24 Amps (PS-8)/0.075 Amps (PS-6) for 24 hours on

battery back up for desired auxiliary equipment. The MP Mode provides up to 2.5

Amps in non-alarm condition or when the input AC is present. Special

Applications, Power Limited.

NAC appliances are connected to these outputs. Each output can supply a

maximum load of 3.0 Amps, Class "B" or 3.0 Amps Class "A" and can be

individually programmed for Wheelock Strobe Sync Mode, Temporal Mode or

Input follower Mode. The outputs can be configured as four Class "B" circuits,

two Class "A" circuits, or two Class "B" and one Class "A" circuits. Outputs are

controlled by a designated input (INPUT 1 or 2) as selected by the DIP switch for

that output. Power Limited.
