Figure 1 and 2 Notes:
1. RPR-1 remote relay and HTRI are used for 24VDC power supervision. 24VDC wire open will
cause trouble reported by HTRI. Refer to Installation Instruction of RPR-1 (315-096055).
2. ABHW-4SZ terminals 5-6 are polarity insensitive. Line 1 and Line 2 can be either line of device
loop.
3. EOL device of HTRI: 3.6K, 1/4W resistor, P/N 140-820185.
EOL device of HTRI: 470 Ohm, 1/4W resistor, P/N 140-820164.
EOL device of XTRI: 470 Ohm, 1% 1/2W Resistor, P/N A5Q00073045.
4. ABHW-4SZ can be wired either Style Z (Class A) or Style Y (Class B).
5. For the max load current, refer to the specifications of the compatible panels listed in this
document.
6. The 24VDC regulated power supply could be the Aux Power Output from the compatible
panels or from PAD-3/PAD-4/PAD-5, or other UL listed 24VDC regulated power supply. 24V
FWR power supply can't be allowed.
