INSTALLATION INSTRUCTIONS
IMPORTANT
Please Read Carefully and Save
This instruction manual contains important information about the installation and operation of bells. Purchasers who
install bells for use by others must leave this manual or a copy of it with the user.
System Sensor supplies bells for nearly all sprinkler/fire alarm/burglar applications.
These instructions apply to all System Sensor bells in the series. Read all instructions carefully before beginning. Follow
only those instructions that apply to the model you are installing.
CAUTION
DO NOT USE IN POTENTIALLY EXPLOSIVE ATMOSPHERES.
DO NOT LEAVE ANY UNUSED WIRES EXPOSED.
GENERAL DESCRIPTION
The National Fire Protection Association has published codes, standards, and recommended practices for the installation and use of the above appliances. It is recommended that the installer be familiar with these requirements, with local
codes, and any special requirements of the authority having jurisdiction.
These bells are intended to be connected to alarm indicating circuits of UL listed fire alarm control panels. Terminal connections are polarized to enable supervision of the installation wiring. The KMS bells require 24 VDC and the KBS bells
require 120 VAC.
Before installing any alarm device, be thoroughly familiar with:
NFPA 72: Installation, Maintenance, and Use of Protective Signaling Systems
NFPA 13: Installation of Sprinkler Systems
NFPA 13A: Inspection, Testing, and Maintenance of Sprinkler Systems, specifically Chapters 4 and 5
Other applicable NFPA standards, local codes, and the requirements of the authority having jurisdiction.
Failure to follow these directions may result in failure of the device to report an alarm condition. System Sensor is not
responsible for devices that have been improperly installed, tested, or maintained.
INSTALLATION
WARNING
High voltage. Electrocution Hazard. Do not handle live AC wiring or work on a device to which AC power is applied.
Doing so may result in severe injury or death.
CAUTION: Do not loop wire under terminals. Break wire runs to provide supervision of connections.
1. Remove the gong.
2. Wire the bell in the circuit. See Figure 1. (Note polarity markings on bells.)
