Edwards Signaling Genesis Ceiling Strobe User Manual

Genesis Ceiling Strobe

Product information

The Genesis Ceiling Strobe is a visible fire alarm notification
appliance designed for indoor ceilings and walls. See Table 1
for a list of model numbers.

The strobe includes a field configurable switch for selecting the
desired candela output. The candela output setting is locked in
place and remains visible after final installation.

This strobe features an enhanced synchronization circuit to
comply with the latest requirements of UL 1971 Signaling
Devices for the Hearing Impaired and the latest Canadian
standard CAN/ULC S526-02. Synchronized operation requires
a separately installed synchronization control module. See
Table 2 for a list of compatible synchronization modules.

Install this device in accordance with applicable requirements
in the latest editions of the NFPA codes and standards and
Canadian Electrical Code, Part 1, Section 32, CAN/ULC S524­01, Standard for the Installation of Fire Alarm Systems, and in
accordance with the local authorities having jurisdiction.

Specifications

Operating voltage

Regulated 16 to 33 Vdc, 16 to 33 Vfwr
This device was tested to the Regulated 24 Vdc/fwr
operating voltage limits of 16 V and 33 V. Do not apply

80% and 110% of these values for system operation.
Strobe operating current: See Table 3
Light output: Selectable at 15, 30, 75, and 95 cd
Synchronization: Meets UL 1971 requirements. Maximum

allowed resistance between any two devices is 20 Ω.

Refer to specifications for the synchronization control

module, this strobe, and the control panel to determine

allowed wire resistance.

Installation Instructions

Warning: To reduce the risk of shock, disconnect all power

and allow 10 minutes for stored energy to dissipate before
handling.

Caution: Electrical supervision requires the wire run to be
broken at each terminal. Do not loop the signaling circuit field
wires around the terminals.

1. Remove the cover by depressing the tab on the side of the
unit with a small screwdriver. Turn the cover
counterclockwise to release.

2. If temporal strobe (private mode) operation is desired, cut
jumper JP1. See Figure 2.

3. Connect the strobe terminals to the signal circuit field
wiring. You must observe polarity for the unit to function
properly. See Figure 3.

4. Slide the candela switch to the desired candela output (15,
30, 75, or 95 cd) by aligning it with the indicator below the
switch. See Figure 4.

5. Mount the unit onto a compatible electrical box. See
Figure 5.

6. Replace the cover by positioning the alignment arrows
together and rotating the cover clockwise.

7. Test the unit for proper operation.

To change the from 1 fps (public
mode) to temporal (private mode) cut jumper JP1
