Potter PE-LFHN Series Installation Instructions

INSTALLATION INSTRUCTIONS
POTTER LOW FREQUENCY SOUNDERS
AND SOUNDER STROBES
WITH PRE-WIRE/PRE-TEST (WALL MOUNT)
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"
IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. FAILURE TO COMPLY WITH ANY OF THE FOLLOWING
INSTRUCTIONS COULD RESULT IN IMPROPER APPLICATION, INSTALLATION AND/OR OPERATION OF THESE PRODUCTS IN
AN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU
AND/OR OTHERS.

** 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.

0.138
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.
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.
