~. L~ ~RD S- PR~ORS
~~1~:
Do not rmove or insert any of the Ho. 685*S drdt cards
tithout first turdng off the
MO. 6X1S AC ~er, ss *1 ss
tisconneetingthe standby battery.
A.
Group E~bsr S~aetion:
The ~oup number is the second digit of the receiver~s display (it follms
the receiver number).
It identifiae the phone line on which a cdl was
received. In the mse where mtitiple @one lines are set up as a rotary
group, the group number may be used to identify the rotary group number.
1. Locate the ~oup nmher sdector stit~ on the ltie card (see Diagra
5).
Hold the line card with the cm~nen~ toward you sod the gold
fingsrs downward.
The switch is a small square com~nant with the
numer~s O to 9 printed on it snd is located in the upper ri@t-h~d
corner of the bo=d.
2. Rotate the canter part of the swit& (use a small screwdriver)until
the *row thereon points to the desired line nwmter (1-8). D O NOT
attampt to use the number O or 9 for the line nmber.
B. ~~ SP~ my Option (No. 685-2 ~GH/LOW SPEED Format Line Csrde otiy):
If an Ademco High Spsed cmunicating devioe is progr~ed to cdl the
No. 685-2 HIGH/LOW SPEED Line Card,
trmsmission shntid occur autma-
,-
tictily at ~GH SFSED. No changes are required at the communieating
detice. The No. 685-2 sends a HIGH SPEED acknowled~ent tone once (or
twice, if necess=y). If a ~GH SPSSD response does not occur , the
No. 685-2 will send a stmdsrd acknowledgment tone.
Standard (LOW SPEED
fomat ) commticating devices can thus operate with the No. 685-2 as well.
It ~so me~s that high speed ~mmunicsting devices (unless specifically
pro~smmed otherwise)wfll transmit at LOW SPEED if, due to line noise, for
e-pie, it fails to respnd to the two HIGH SPEED achowledgments . In
some communicators,if they have been programmed for a four-digit acmunt
n~ber (i.e.~ ~~ting ~t a =ro in the first position), the account
nm~r will change at
LOW SPEED (e.g.,
1258 becom= 0258).
To avoid
possible errors, we recommend otiy having high speed communicatorscdl in
to a No, 685-2 card dedimted to HIGH SPEED ofly.
To convert the card to a ~~ SPSSD ofiy card, cut the WHITE loop jm~r
located in the upper right-hand corner of the line card. %ke sure that
the free ends of the wire mnnot short to any adjacent sre~ .
c.
Slff Cmunicatw Option:
The No. 685 will wait up to 3.5 seconds tetween the end of the handshake
tone and the start of the first message.
Also, it will wait up to 5
seconds tetweenmessages before hsn~ng up.
