This strobe features an enhanced synchronization circuit to
comply with the latest requirements of UL 1971. Synchronized
operation requires a separately installed synchronization

device. See the control panel or power supply compatibility list
for compatible synchronization devices.

Description

The Genesis Low Frequency (520 Hz) Horn-Strobe can be
used for applications where a low frequency alarm notification
appliance with strobe light output is required. The device is
designed for wall mounting and indoor use only. See Table 1
for a list of model numbers.

When this device is used as a low frequency sounder in
sleeping quarters, the strobe's candela switch (Figure 1) must
be set to 110 cd.

The horn-strobe includes field-configurable jumper options for
selecting:

• Temporal or steady horn output

• Low dB or high dB output

• Temporal or continuous pattern strobe

The horn-strobe also includes a field-configurable switch for
setting the strobe candela level. This setting is locked in place
and is visible after final installation.

Installation

Install and wire this device in accordance with applicable
national and local codes, ordinances, and regulations.

The horn-strobe should be mounted so that the entire lens is
not less than 80 in. (2.03 m) and not greater than 96 in.
(2.44 m) above the finished floor. The entire lens should also
be 24 in. (61 cm) or more from the finished ceiling.

WARNING: Electrocution hazard. To avoid personal injury or

death from electrocution, remove all sources of power and
allow stored energy to discharge before installing or removing
equipment.

Note: Electrical supervision requires that you break the wire

run at each terminal. Do not loop wires around the terminals.

To install the horn-strobe:

(1) Jumper JP3
(2)

(3) Jumper JP1
(4)

notch

(1) Compatible electrical box
(2)
(3) Horn-strobe

(4) 8-32 x 1 in. screw, provided

(5) Cover

1. Remove the cover by using a screwdriver to depress and

slightly twist both tabs on top of the unit.

2. Set the horn signal, sound output level, and strobe signal
to the desired settings. See Figure 1.

To change the horn output level from high dB to low dB,
cut jumper JP3.

To change the horn signal from temporal to steady, cut
jumper JP2.

To change the strobe pattern from continuous to temporal
(private mode), cut jumper JP1.

3. Set the candela output.

Slide the candela switch to the desired candela output by
aligning it with the indicator notch below the switch. See
Figure 1.

4. Mount the horn-strobe as follows.

Note: Route the signal circuit field wiring through the

cutout in the center of the horn-strobe.

Flush mount: Mount the horn-strobe and flush mount

spacer onto a compatible electrical box (Figure 2), making
sure not to overtighten the mounting screws. See
“Specifications” for compatible electrical boxes.

Surface mount: Mount the G4B or G4RB surface mount

box on the wall (Figure 3), and then secure the appliance
to the box using the fasteners provided with the box.

5. Connect the signal circuit field wiring to the horn-strobe
terminals (Figure 4). Observe polarity for the unit to
function properly.

6. Replace the cover by aligning it at the bottom, and then
snapping it in at the top.

7. Test the unit for proper operation.
