Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
The Potter Electric series PE-LFHN Sounder (520Hz) and PE-LFHS Sounder Strobe (110/177cd) appliances are designed for easy
installation with a pre-wire capable mounting plate. All models are for 24V operation. The PE-LFHN Sounder and PE-LFHS Sounder
Strobe are rated as low frequency devices per UL 464, suitable for sleeping areas per NFPA 72. The PE-LFHN sounder may be wall or
ceiling mounted.
The Potter PE series meets NFPA 2016 20 millisecond light pulse duration code requirements. The maximum number of PE series devices
per NAC is determined by dividing the maximum current rating of the FACP NAC by the total current rating of one PE series device, with a
maximum of 105 PE series strobe devices per NAC. Refer to FACP installation instructions for more detail.
The Potter PE series Multi-Candela Strobes provides a synchronized strobe appliance when used in conjunction with an FACP or power
supply that incorporates the Wheelock Sync protocol.
CAUTION: Do not change factory applied finishes. “DO NOT PAINT”.
ATTENTION: Ne pas modifiez les finitions appliquées en usine. “NE PAS PEINTURER”

** Setting 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.
Important: 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 the operating effect can be seen by all intended viewers. Furthermore, the intensity,
number, and type of strobes shall be sufficient to alert the intended viewer with proper illumination, regardless of the viewers orientation.

Figure 2:
1. This model has in-out 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.
2. Break all in-out wire runs on supervised circuits to assure integrity of circuit supervision as shown in
Figure 2. The polarity shown in the wiring diagrams is for operation of the appliances. The polarity is
reversed by the FACP during supervision.
NOTES:
1. The strobe will produce 1 flash per second over the "Regulated Voltage" range.
2. Strobe are not designed to be used on coded systems in which the applied voltage is cycled on and off.
3. The maximum number of PE series strobes on a single notification appliance circuit shall not exceed 105.
4. These appliances are UL Listed as “Regulated”. They are intended to be used with FACPs whose notification circuits are UL Listed
as “Regulated.” Refer to the FACP instructions for special application and strobe synchronization compatibility.
5. These appliances were tested to the regulated voltage limits of 16.0-33.0 Volts. Do not apply voltage outside of this range. 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 max wire impedance between strobes shall not exceed 35 ohms.
6. Make sure that the total RMS current required by all appliances that are connected to the system’s primary and secondary power
sources, notification appliance circuits, sync modules, or Potter power supplies does not exceed the power sources rated capacity or
the current ratings of any fuses on the circuits to which these appliances are wired.
7. The Code 3 temporal pattern (1/2 second on, 1/2 second off, 1/2 second on, 1/2 second off, 1/2 second on, 1-1/2 off and repeat) is
specified by ANSI and NFPA 72 for standard emergency evacuation signaling. Code 3 Horn shall be used only for fire evacuation
signaling and not for any other purpose.
8. The Code 4 temporal pattern (100 ms on, followed by 100 ms off, for 4 cycles, followed by 5 seconds of silence and repeat), is specified
by ANSI and NFPA 720 for carbon monoxide emergency signaling.
9. The effect of shipping and storage temperatures shall not adversely affect the performance of the appliance when it is stored in the
original cartons and not subjected to misuse or abuse.

Factory Setting is T3 - 110cd
Strobe device has only one mounting orientation. LED light element should be oriented toward the floor
The 110/177 candela strobe is Listed for use in sleeping or non-sleeping areas when installed in accordance with appropriate NFPA
Standards and the Authority Having Jurisdiction.
NFPA 72/ANSI 117.1 provide means for determining equivalent illumination using fewer, higher intensity strobes within the same protected
area.
Application Notes: T3/T4 Operation with Wheelock Sync
T3/T4 Sync Selectable operationrequires Wheelock Sync (using Silence/Resound Commands). All appliances must be set to T3/T4. Code
4 (T4) operation occurs with Wheelock Sync Resound Mode (No Silence). Code 3 (T3) operation occurs with Wheelock Sync Silence Mode
(Audible Silence function is available only when using Continuous or T3 setting). A Wheelock DSM-12/24-R sync module may be used to
facilitate T3/T4 operation.

MOUNTING OPTIONS:
The following figures (A thru C) show themaximum number of field wires (conductors) that can enter the backbox used with each mounting
option. If these limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires and stresses from the
wires could damage the product.
Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and conduit, especially if
sheathed multiconductor cable or 3/4" conduit fittings are used.

All installations shall be in accordance with:
1) In the United States, the National Electrical Code, NFPA 70, and the National Fire Alarm and Signaling Code, NFPA 72.
2) In Canada, CSA C22.1, Canadian Electrical Code, Part I, Safety Standard for Electrical Installations, Section 32; and the Canadian
Standard for the Installation of Fire Alarm Systems - CAN/ULC-S524.
MOUNTING PROCEDURES:
1. Select a mounting option and install the backbox. Surface back box requires 5 1/8” spacing for surface mounting. Screws are
provided. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product. Do
not pass additional wires (used for other than the signaling appliance) through the backbox. Such additional wires could result in
insufficient wiring space for the signaling appliance.
2. Install the Mounting Plate on the backbox with “TOP” facing up. Use 6-32 screws for Single/Double Gang back-box, 8-32 screws for
4” back-box or hi-lo screws for the surface back box.
3. Pre-Wire: Connect field wires to terminals on mounting plate (reference Figure 1 and 2). Use care and proper techniques to position
the field wires in the backbox so that they use minimum space and produce minimum stress on the product. This is especially
important for stiff, heavy gauge wires and wires with thick insulation or sheathing. When terminating field wires, do not use more
lead length than required. Excess lead length could result in insufficient wiring space for the signaling appliance.
4. Pre-Test: Mounting Plate contains a SHUNT between adjacent “+” terminals to facilittate testing before device is attached.
Note: Shunt will open permanently when device is installed on mounting plate.
5. Verify appliance settings are correct for your application. Settings are shown in Figure 3. Factory settings is Code 3 (T3), and 110cd.
Use Code 3 (T3) for fire emergency only, and Code 4 (T4) for carbon monoxide (CO) emergency only.
6. Place the appliance over the mounting plate. Engage TOP hook on mounting plate, then secure with screw at the bottom. Use care
to prevent speaker cone damage when driving the screw.
7. Align cover to the appliance with strobe opening over LED lens. Then, snap the cover in place.
8. To remove the appliance, insert a small flat-bladed screwdriver into the bottom opening ½” as shown in Figure 5. Then lift off grille.
Important: Do not fully back out terminal screws. Do not over tighten screws or terminals. Excessive torque may affect
operation. When using power tools, ensure the torque is set to the lowest setting available.
NOTE: Final acceptance is subject to Authorities Having Jurisdiction.
Check the installation instructions of the manufacturers of other equipment used in the system for any guidelines or restrictions on wiring
and/or locating Notification ApplianceCircuits (NAC) and notification appliances. Some system communication circuits and/or audio circuits,
for example, may require special precautions to assure immunity from electrical noise (e.g. audio crosstalk).
