Application Notes:
CAUTION: Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and conduit, especially if
sheathed multiconductor cable or 3/4” conduit fittings are used.
1. Mounting hardware for each mounting option is supplied.
2. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product. When extension rings are
required, conduit should enter through the backbox, not the extension ring. Note not all Canadian Extension Rings fit Series E. Call factory for
assistance.
3. When terminating field wires, do not use more lead length than required. Excess lead length could result in insufficient wiring space for the signaling
device.
4. Use care and proper techniques to position the field wires in the backbox so that they use minimum space and produce minimum stress on the
product. This is especially important for stiff, heavy gauge wires and wires with thick insulation or sheathing.
5. Do not pass additional wires (used for other than the signaling device) through the backbox. Such additional wires could result in insufficient wiring
space for the signaling appliance.
6. Frequency range of speakers is 400-4000 Hz.
7. A blocking capacitor for DC supervision of audio lines by the FACP is factory wired in series with the speaker input 1.5uF for 25 VRMS speakers
and 0.15uF for 70 VRMS speakers.
CAUTION: Always operate audio amplifiers and speakers within their specified ratings. Excessive input may distort sound quality and may damage
audio equipment. Do not exceed =130% of speaker rated voltage per CS 243. Improper input voltage can damage speaker. If distortion is heard, check
for clipping of the audio signal with an oscilloscope and reduce the amplifier input level or gain level to eliminate any clipping.
