Continuous 12V.M: Auxiliary Power for Accessories: Observe

polarjty.

These terminals provide power for accessories such

as space protection devices, e.g. ultrasonic or passive infrared

detectors, photoelectrics,.etc.

The

total

combined current drain from these terminals and the

smoke detector power terminals (3,4) must not exceed 300 MA.

(See SPECIFICATIONS).

7(+). 8(-I

Alarm Roll Voltage:

These terminals provide lLV.BC during an

audible alarm, at a drain of up to 2A. This output is steady

for burglary and audible panic and pulses for fire.

AWITIOWAL CONECTION POSTS (See Oiagram 9)

These posts are provided to permit the connection of accessory devices

(such as the ND. 674 Select-A-Line and the No. 675 Ground Start ,Hodule)

that require special signals.

GROUND START OUTPUT POST:

An output point to provide a mtnnentary

input (until dial tone is obtained) to a No. 675 Ground Start Module

which causes its

relay

to momentarily ground the incoming phone line

for the purpose of obtaining a dial tone outboard of a PBX.

ALTERNATE lElC0 CIIL WfPlll

POST:

An output point that only provides

an alternate line selection request to a No. 674 Select-A-Line if

there is a failure to receive "Kissoff" from the primary telco line

receiver.

If there is a failure to receive *Kissoff" on the first

attempt, this output will request service from the alternate phone

line.

If there is a'failure to receive "Kissoff" on the alternate

phone line, this output will switch back to primary line selection.

a No. 659' Telco Line Fault Monitor is used and detects a line

cut, it will override the al ternate line selection described here

and maintain transmission on the intact line.

*Use of this product will Fe&ire usage of a No. 687 Voltage Regulator

to develop the power necessary to operate the b. 659.
