Instructions
ELK-150RT
Install top edge of backplate at least 1"
below any soffit or building overhang.
The ELK-150 RT is a self-contained siren in a tampered "No Rust" stainless steel
enclosure. It incorporates two sealed reed tamper switches for enhanced
reliability and ease of use.
1.
Using the backplate as a template, mark and drill the 4 mounting holes and
the wire or conduit entry hole (see Figure 1). Insert the (4) 1/4 x 1” wall
anchors, then partially install the top two #10 x 1” screws.
2.
Route the wire or conduit through the hole provided and hang backplate on
the top screws. Then install remaining two screws and & tighten all four.
3.
Temporarily hang the Siren/speaker on the backplate by aligning the slotted
insert on the top edge of the Siren with the 1/2" recessed tab on the bottom
edge of the backplate. Press Siren onto tab. (See Figure 2)
4.
Connect the two white wires from the tamper switches to a 24 hour closed
loop on the control panel (the switches are already connected in series).
5.
Connect the
Red
(+)
and
Black (-)
wires from the Siren to the control's
alarm
output
.
The Siren produces a Yelp sound from a constant voltage input. If the
voltage input is pulsed the siren produces a low pitch rise. This
ComboTrigger
TM
feature allows two sounds to be activated by a control that
has only a single alarm output with a pulse option. Recommended wire
gauge from control is 18 AWG.
NEG (-) Black
= Negative (-) terminal from Control's Alarm output.
YELP (+) RED
= Positive (+) terminal from Control's Alarm output
NOTE:
The Siren is factory set for maximum loudness and current draw. To
change the unit for lower current draw and loudness, remove the four screws
and cover from the back of the siren. Find the Red speaker wire and follow it
to where it solders to the circuit board. Cut this Red wire approx. 3" back from
the board. Find the unused Yellow wire that is soldered to the circuit board.
Using the provided wire nut, splice the Red wire from the speaker to the
Yellow wire going to the board.
6.
Move the Siren/speaker from its hanging position to its final mount by aligning
it's top and bottom slots with the 1/2" tabs on the top edge of the backplate
and in the bottom center above the bolt threads. (See Figure 3) Press firmly.
7.
Slide front cover over speaker. Lift up to engage the tabs in the cover with the
two "U" shaped slots on the top edges of the backplate. (Figure 4) Lower
cover until tabs are in slots. Push cover towards wall, then lift up to lock tabs
in slots. Thread 1/4-20 hex bolt into hole on bottom of cover and tighten until
secure.
8.
The front cover tamper switch is pressed closed by the front cover during the
final 3 to 4 full turns of the hex bolt. If possible, test the operation of the
tamper switch using a continuity meter.
Note: The ELK-150RT is designed for Single Output Alarm Controls that use
a STEADY Output for BURG or a PULSING Output for FIRE. For an Alarm
Control panel that has separate BURG and FIRE alarm outputs connect the
Red wire to each output, then program one output for Steady(Burg) and the
other for Pulsing(Fire). Connect the Black wire to Neg.
