SPEAKER The ELK-100 has 3 speaker terminals. Terminal HIGH is for high volume (max. current draw), LOW is for low
HOOKUP volume (min. current draw), and SPKR is a common terminal. The unique benefits of having 3 terminals are:
1. Two volume levels can be obtained simultaneously from two speakers (ie: one indoor, the other outdoor).
2. Current draw can be minimized (MilliMiserTM ) by connecting speaker(s) to terminals SPKR & LOW only.
3. Maximum volume can be obtained by connecting speaker(s) to terminals SPKR & HIGH only.
4. Low wattage speakers (10 to 15 watts) may be connected to SPKR & LOW with no danger of burnout.

Always add a 1.5 Amp fuse in series with outdoor
speaker(s). Shorting of the outdoor speaker wires will
blow this fuse and allow other speaker(s) to operate.
Note: This speaker
will be louder than
the other two.

NOTE: While normal resistance for a single alarm speaker is 6.5 to 8 Ohms, total resistance (or load) changes when multiple speakers
are wired together in series or parallel. Total resistance should never be less than 4 Ohms on either the SPKR & LOW or the SPKR
&HIGHterminalconnections. RefertoTable1andthediagramsbelowforwiringmultiple8Ohmspeakersinparallelorseriestomaintain
a load between 4 and 16 Ohms.
MilliMiserTM Connecting the speaker(s) to the LOW and SPKR terminals allows current draw to be reduced by approximately 25%
with only 6 to 8% less sound.
VOLTAGE Connect the 3 terminals on the ELK-100 to the control panel alarm output as follows:
INPUTS +STDY (Red) = Steady Channel generally connected to the alarm output terminal for Fire.
NEG. (Black) = Common Negative (-)
+YELP (Yellow) = Yelp Channel generally connected to the alarm output terminal for Burglary.
ComboTriggerTM Forcontrolswith only a singlealarmoutput, connect the NEGand+YELP to the alarmoutputandprogram the control
to pulse the output (if available) for Fire. Pulsing the +YELP input on/off at a 1 sec. duty cycle produces a unique slow sweep sound
which draws attention and helps identify Fire from Burg.
DELETE SLOW SWEEP STARTUP:
Cut Resistor R18 to delete the slow sweep startup on the Yelp channel.
WARNING: The purpose of the slow sweep startup is to provide a
unique sound pattern (ComboTrigger) to identify Fire from Burg if
Yelp input is pulsed by a control with only a single alarm output.
