General

The LED Horn Strobe is designed for easy installation. The model is for 24VDC operation.

NOTE: Candela will determine the current draw of the product.

When calculating the total currents, use Table 2 to determine the highest value of RMS current
for an individual appliance, then multiply these values by the total number of appliances. Be
sure to add the currents for any other appliances, including audible signaling appliances
powered by the same source, and to include any required safety factors.

WARNING:

Please read these instructions carefully before using this product. Failure to comply with any of
the following instruction, cautions and warnings could result in Improper application, candela setting,
installation and/or operation of this product in an emergency situation, which could result in property
damage and serious injury or death to you and/or others.

1 / 8

NOTE: These appliances were tested to the regulated voltage limits of 16.0-33.0 Volts. Do
not apply voltage outside of this range.

NOTE: Check the minimum and maximum output of the power supply and standby battery
and subtract the voltage drop from the circuit wiring resistance to determine the applied voltage
to the strobes. The maximum wire impedance between strobes shall not exceed 35 ohms.

NOTE: Strobe and horns are not designed to be used on coded systems in which the
applied voltage is cycled on and off.

NOTE: Make sure that the total rms (RMS) current required by all appliances that are connected
to the system’s primary and secondary power sources, notification appliance circuits does not
exceed the power sources’ rated capacity or the current ratings of any fuses on the circuits
to which these appliances are wired. Overloading power sources or exceeding fuse ratings
could result in loss of power and failure to alert occupants during an emergency, which could
result in property damage and serious injury or death to you and/or others.

NOTE: The Temporal 4 pattern (0.1 second on, 0.1 second off, 0.1 second on, 0.1 second off,

0.1 second on, 0.1 second off, 0.1 second on, 5 secs off and repeat) is specified by ANSI
and NFPA 72 for standard emergency evacuation signaling.

WIRING, SETTINGS AND MOUNTING

The LED Horn Strobe and Horn appliance has 2 wiring terminals that accept two #12 to #18
American Wire Gauge (AWG) wires at each screw terminal. Strip leads 3/8 inches and connect
to screw terminals.
Break all 2 wire runs on supervised circuits to ensure integrity of circuit supervision as shown
in Figure 2. The polarity shown in Figure 2, the wiring diagram, is for the operation of the
appliances. The polarity is reversed by the FACP during supervision.

NOTE: Wiring method shall be in accordance with CSA C22.1, Canadian Electrical Code, Part 1,
Safety Standard for Electrical Installations, Section 32.

NOTE: Do not fully back out terminal screws.

NOTE: Horn setting Tone Selector switch is shown in Figure 3; settings are T4 H, T4 L, CONT H,

CONT L for Temporal 4 High, Temporal 4 Low, Continuous High, Continuous Low,
respectively.

NOTE: Refer Figure 4 to connect horn/strobe with standalone detector and figure 5 for Macurco
control panels and synchronization module.

CAUTION: Check that the installed product will have sufficient clearance and wiring
room prior to installing back boxes and conduit.
CAUTION: Do not over tighten mounting screws. Excessive torque can distort the base
and may affect operation.
CAUTION: When using power tools to screw down the mounting plate to the electrical back
box, ensure the torque is set to the lowest setting available.

IMPORTANT: Device only has one mounting orientation. LED light element should be pointed towards

WARNING: When installing strobes in an open office or other areas containing partitions or other
viewing obstructions, special attention should be given to the location of the strobes so that their
operating effect can be seen by all intended viewers, with the intensity, number, and type of strobes
being sufficient to make sure that the intended viewer is alerted by proper illumination, regardless of
the viewer’s orientation.

WARNING: A small possibility exists that the use of multiple strobes within a person’s field of view,
under certain circumstances, might induce a photo-sensitive response in persons with epilepsy. Strobe
reflections in a glass or mirrored surface might also induce such a response. To minimize this possible
hazard, it is strongly recommended that the strobes installed should not present a composite flash rate
in the field of view which exceeds five (5) Hz at the operating voltage of the strobes.

It is also strongly recommended that the intensity and composite flash rate of installed strobe and horn
comply with levels established by applicable laws, standards, regulations, codes and guidelines.
