GENERAL INFORMATION

 

Wiring

Use #22 AWG minimum for sensor wiring and digital

 

communicator channels. Use #18 AWG minimum for AC power.

 

All wire should be UL-listed

Environment

The system is designed to work in an indoor heated environment

 

(40 to 120 degrees F.) Battery life may be significantly reduced if

 

components are in direct sunlight or in an unheated location.

U.L. Requirements

UL requires that any fire application includes either a Supervised

 

Smoke Detector Transmitter or a Universal Transmitter

 

configured for fire and connected to a UL-listed single station

 

smoke detector with relay. Other types of smoke/fire sensors

 

(suck as heat sensors) may be included in the system.

 

The Universal Transmitter sbould be used in its supervised mode

 

unless it is being used as a portable device.

 

If the internal sounder on the Central controller or Wireless

 

Siren/controller is silenced for intrusion alarms (DIP switch

 

option) there should be an auxiliary sounding device in the system.

 

The Wheelock EH-EL2 series electronic horn should be used as a

 

siren or horn interface.

 

Open loop sensor connections at any transmitter or Central

 

Controller should be less 3 feet in length with no barriers in

 

between, and the sensor shall be provided with a test feature.

 

All sensors should be UL-listed.
