Edwards Signaling CS405 - Manual

Installation Instructions for Strobe Signal Appliance
1. For indoor mounting, select a Standard North American 2 gang X 1-1/2"
(38 mm) deep electrical box (52151 Series or equivalent). For outdoor
mounting, use a weatherproof model 449 backbox. Install the electrical
box using suitable hardware.
2. Bring signaling circuit field wiring into the electrical box.
CA CA CA CA CAUTION: UTION: UTION: UTION: UTION: Electrical supervision requires wire run to be broken at each
device. Do not loop signaling circuit field wires around terminals.
3. Connect this unit to a signaling circuit that outputs a constant (not
pulsed) voltage. To ensure proper unit function, polarity must be
observed. Refer to Figure 2 for wiring connections. For additional
wiring connection details, see the installation instructions supplied with
the control panel.
4. When connections are complete, mount the unit onto the electrical box as
follows:
a.
For indoor mounting, secure the unit using two Phillip head screws
(supplied). Complete the enclosure by installing two hole plugs
(Part Number P-038845-0019 (supplied)) into the two unused holes
in the back plate.
b. For outdoor mounting, secure the unit using the four Phillip head
screws (supplied). Discard the two plastic caps (supplied).
5. Apply power and activate the unit to verify that it is operating properly.
MAINTENANCE
CA CA CA CA CAUTION: UTION: UTION: UTION: UTION: Should the unit fail to operate properly, do not attempt repair.
Contact the supplier for replacement.
Perform a visual inspection and an operational test twice a year or as directed
by the local authority having jurisdiction.
DESCRIPTION
The strobes are high quality notification appliances intended for public
mode applications in accordance with the latest edition of NFPA 72,
National Fire Alarm Code. It is recommended that these products be
installed in accordance with the requirements in the latest edition of
national and local fire alarm and electrical codes. The 15/75 cd model and
the 110 cd model strobes are suitable for indoor or outdoor applications.
For outdoor use, the strobes must be installed with a weatherproof
backbox, model 449.
The strobes are self-synchronized to flash at 1 fps across their full
operating voltage range. Studies show that people with photosensitive
conditions may experience a photoconvulsive response from random
flashes of light. This risk is minimized with these strobes. The strobe
operates on any existing 2-wire signal circuit. Separately installed "sync
control modules" are not required.
Synchronization of less than 200 milliseconds will be maintained for no
less than 60 hours supervision followed by 30 minutes in alarm.
See Figures 3 and 4 for product specifications.
INSTALLATION
W W W W WARNING: ARNING: ARNING: ARNING: ARNING: This device will not operate without electrical power. As fires
frequently cause power interruptions, discuss further safeguards with your local
fire protection specialist.
To reduce the risk of shock, always disconnect all power before handling
the unit.
To reduce the risk of shock, do not tamper with unit when circuit is energized.
Disconnect all power and allow 5 minutes for stored energy to dissipate
before handling.

CAUTION: This unit is designed to be used on signal circuits that output a constant voltage of 20-24 VDC. 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 strobe terminals.
