ection Systems and notification signals for the purpose of life
safety and property protection. They meet or exceed NFPA/ANSI
standards and UL 464/UL1638.
The CSH24CH is a
Select
-A-
Horn
with the highest strobe light out-
put (non-selectable candela). The colored light is available in Amber,
Blue, Green and Red. The light output candela ratings vary depend-
ing on the lens color.
In those instances where two or more AMSECO horns and/or
strobes are connected and requires a synchronized code 3 temporal
pattern and/or a synchronized strobe flash, all models can be syn-
chronized when used in conjunction with AMSECO UL listed Sync
module SMD10-3A to meet the latest code.
Features
· Available colored lights: amber, blue, green, red

or unfiltered FWR input voltage
· Horn field selectable tones: 3000Hz interrupted or Electro-
mechanical Temporal or Non-temporal High or Low dBA output
· Minimum one flash per second (1Hz)
· All models mount to 4" X 4" X 1-" back box
· Synchronization requires an AMSECO SMD10-3A Sync Module
· RBX-1 back box skirt for surface mount (optional)
· The SPC-1 retrofit plate allows mounting to a variety of back boxes

WARNING
The Strobe/Horn must be used only on circuits with continuously operating voltage. DO NOT use strobe on coded or interrupted circuits in
which the applied voltage is interrupted ON and OFF as the strobe may fail to flash. The applied voltage must be within its rated input voltage range. Fuse
ratingson signaling circuits must handle peak currents from all devices connected to those circuits.

The audible and colored visual alarm indicating appliance shall be AMSECO model CSH24CH or equivalent device. The
Horn/Strobe shall be listed under UL 1971 and UL 1638 Standard for signaling devices and shall be approved for fire protective
and emergency services. The reflective mirror shall be of the same color as the lens of amber, blue, green, or red. The can-
dela output shall have a single setting of High intensity output. The Horn shall provide two different field selectable tones and a
High and Low field sound output setting. The signaling Horn/Strobe shall operate on 24VDC from a non-coded regulated DC
supply or full-wave rectified, unfiltered supply. The signaling strobe shall be designed to produce a signal flash of one flash per
second with continuously applied minimum voltage. The Horn/Strobe shall be capable of CEILING and WALL mounting to a
variety of back boxes using the AMSECO SPC-1 retrofit back plate. When strobe synchronization is required, the Horn/Strobe
shall be compatible with the AMSECO SMD10-3A (daisy chain) or other source of AMSECO sync protocol.

Description
The Sync Module is designed to provide a synchro-
nized temporal pattern (code 3) tone, and synchronize
the strobe flashes when used with AMSECOs

series as well as the ability to silence the horn while
maintaining the strobe flashes.
The SMD10-3A has the capability of connecting two
style Y (Class B) circuits or one style Z (Class A) circuit
and is rated for 3 Amperes per circuit.
The SMD10-3A can be interconnected so that more
than 2 alarm zones can be synchronized by connecting
the SYNC terminals (daisy chain connection). The max-
imum number of interconnected modules is twenty. All
inputs are polarized for compatibility with standard
reverse polarity supervision of circuit wiring by F.A.C.P.
