Installation Manual

The panel has seven screw terminals and two telephone connections (Figure 5). The screw terminals connect 
AC power, sirens, and/or hardwired detectors. 

Program sensors and devices before you install them. Follow the instructions in   to add the sensors to panel 
memory.  

The HW1 I/O terminal is dual purpose and can be used for either siren or hardwired contact connections. The 
HW2 in terminal is an input only. 

From the factory, the HW1 I/O input is set up for interior siren operation (status and alarm sounds). HW1&2 
DC out provides the positive (+) voltage.

Note:  The total current available from the HW1&2 DC out terminal is 250 mA at up to 120°F (49°C). A 24-hour battery standby for 

UL Requirements will be met with a maximum load of 250 mA.

With Hardwired Siren Supervision turned on, sirens connected to HW1 I/O are supervised and require a 
4.7 kohm resistor in the circuit. If this terminal is not used, turn Hardwired Siren Supervision off.
