Strobe Signals
Features
• Low current draw synchronous
strobe
• Supervised wiring

Description
The Edwards 2440S & 2441S Series
synchronous strobes are visual alarm
signals designed for use in fire alarm
applications.
The strobes employ a unique microprocessor design that assures all units
operate at the same time and at a
rate of one flash per second thereby
reducing the risk of causing disorientation of a small portion of the population having photosensitivity.
Screw terminals are provided for
easy installation. The strobes require
a continuous (non-pulsed) DC source.
Agency Approvals
• Strobe: UL 1971 Listed for the
Hearing Impaired
• Strobe: UL 1638 Listed Private
Mode (Indoor and not for the hearing impaired)
• Meets NFPA and ADA require-
ments
• Engineered thermoplastic housing
UL flame rated 94V-0
Specifications
• See Specification Information Table
on page 12-24.
Installation
See Strobe Application Data, page
12-38, for the following: sizing wall
and ceiling mounted strobes to room
size, mounting strobes in corridors,
and mounting strobes in sleeping
rooms.
See System Design Criteria on page
12-51.
Applications
The 2440S & 2441S series strobe is a
visual signaling appliance for installations that operate in conjunction with
an installed fire alarm panel and detection devices.

CAUTION: This unit is designed to be used on signal circuits that output a constant voltage of 20-24V DC. Do not connect this unit
to a coded or pulsating voltage. Electrical supervision requires wire run to be broken at each terminal. Do not loop signaling circuit field wires around terminals.

† The 2440S & 2441S strobes are available with either a red faceplate or a white faceplate; for a red faceplate, put an "R" in this position
and for a white faceplate, put a "W" in this position.
Note 1: Connected to filtered DC source.
Note 2: Connected to unfiltered DC source (full wave rectified)
Note 3: Use the peak current rating to establish the maximum number of strobes, wire gauge and standby power requirements. Consult
the panel manufacturer to determine the maximum number of strobes for each signaling circuit.
Note 4: Peak inrush current at 24V DC for less than 50 microseconds.
