NOTES:
1. Observe polarity of power supply connections.
Application of voltages greater than 18 VDC may
result in damage to unit.
2. If EVD-R remote pickups are installed, remove the factory installed, 10K Ohm, 1% end of line
resistors from pins 4-5 and pins 5-6. See Figures 2a and 4 for details.
3. Connections to optional RTA, Remote Test Annunciator, or dry contacts from any UL listed central
station test unit. See Figure 5 for details.
4. Remote annunciator terminal provides power-limited +12 VDC when alarm contact is in its ALARM
state. Limit current draw to 10mA.
5. Remote annunciator terminal provides power-limited +12 VDC when tamper alarm contact is in its
TAMPER state. Limit current draw to 10mA.
6. Pins 1-15 are power limited.
