Mounting

PA400 Sounders

1. The PA400 is intended for mounting to a standard 2-1/2" deep single-gang box which allows sufficient clearance for conduit entrance.

2. The PA400 is compatible with DC line supervision. The Piezo Alert is polarized and has terminals marked with polarity. Apply positive supply voltage to the (+) terminal and negative supply voltage to the (–) terminal. (See Figure 5.)

3. Mount the appliance to the electrical outlet box using the two mounting screws supplied.

4. Field repair of the PA400 should not be attempted. Return to factory for repair or replacement.

PS12 or PS24 Strobes

These optional strobes are interconnected to the PA400 by first removing the two mounting screws from the sounder. Use a small screwdriver to punch out the skinned-over areas as indicated in Figure 6. Install the adapter plate on top of the sounder and screw the combined sounder and adapter plate to the electrical outlet box. Make sure field wiring terminals are oriented in the upward position when mounted in the outlet box. Next, slide the strobe directly into the slots in the plates. The positive solder lug may be colored red or marked with a plus sign (+). This lug must be in the slot closest to the field wiring terminals. Grasp the catch area on each end of the strobe and squeeze while applying inward force. Make sure the strobe catches fully engage the slots in the adapter plate and that no gap appears at the interface between the strobe and adapter plate.

The Limitations of Sounder/Strobes

The Sounder and/or Strobe will not work without power. The sounder/ strobe gets its power from the fire/security panel monitoring the alarm system. If power is cut off for any reason, the sounder/strobe will not provide the desired audio or visual warning.

The Sounder may not be heard. The loudness of the sounder meets (or exceeds) current Underwriters Laboratories’ standards. However, the sounder may not alert a sound sleeper or one who has recently used drugs or has been drinking alcoholic beverages. The Sounder may not be heard if it is placed on a different floor from the person in hazard or if placed too far away to be heard over the ambient noise such as traffic, air conditioners, machinery or music appliances that may prevent alert persons from hearing the alarm. The Sounder may not be heard by persons who are

hearing impaired.

must be installed within an area where it can be seen by building occupants. The strobe must not be installed in direct sunlight or areas of high light intensity (over 60 foot candles) where the visual flash might be disregarded or not seen. The strobe may not be seen by the visually im-

paired.

The signal strobe may cause seizures. Individuals who have a positive

photic response to visual stimuli with seizures, such as epileptics, should avoid prolonged exposure to environments in which strobe signals, including this strobe, are activated.

System Sensor recommends that the Multi-Alert Sounder and Signal Strobe always be used in combination so that the risks from any of the above limitations are minimized.

The Signal Strobe may not be seen. The electronic visual warning signal that flashes at least once every three seconds meets or exceeds current Underwriters Laboratories’ standard 1971 and uses an extremely reliable xenon flash tube. The visual warning signal is suitable for direct viewing and
