The E70 Fixed‑Candela Speaker Strobes provide high
audio output with clear audibility, and are designed to
meet the critical needs of the life safety industry for
effective emergency voice communications, tone
signaling and visible signaling to alert the hearing
impaired.
A speaker mounting plate with a built‑in level
adjustment allows for a faster and easier installation.
The two‑screw grill cover creates an attractive
appearance.
The high‑efficiency speakers are designed for
maximum output at a minimum wattage across a
frequency range of 400 Hz to 4 kHz.
When used with the SM (single) or DSM (dual)
Synchronization Modules, the strobe produces a
synchronized flash for compliance with ADA guidelines
concerning photosensitive epilepsy. All strobe input is
compatible with standard reverse polarity type
supervision of circuit wiring by a fire alarm control
panel (FACP).
u Listed at 15 cd, but providing 75 cd on axis

For synchronization, use the SM or DSM modules
with these control panels. The synchronization module
must be set for 24 V operation. When used, the D7022
must be set for 24 VDC operation.

When used with a D7039 Multiplex Expansion
Module, the FPD-7024 and D7024 become
addressable fire alarm control panels (FACPs).
Mounting
The low profile design of these notification appliances
creates more wiring space in standard electrical back
boxes. The speaker mounting plate incorporates a
built‑in level adjustment feature allowing for a faster
and easier installation.
These speaker strobes mount on the indicated back
boxes for the indicated applications:
