Remote alarm lamp (ceiling) 

 
 

 

Note: 

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-4BZ 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. 
4.  ABHW-4BZ 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.
