Inputs
The wiring of supervised inputs is shown in the next two figures. Note that the resistor
network is different for NO and NC switches.
Normally Open (NO) Wiring
Normally Closed (NC) Wiring
NOTE
To comply with UL requirements, use shielded, minimum 22 AWG stranded,
twisted pair cable for monitor points, DSMs, and REXs. Use Belden 9462 or
equivalent.
Outputs
The outputs are dry contact Class C relays that are rated at 5 amps. Since they are dry
contact, the technician must supply external power. The following two examples show
an electric strike wired as both Fail Secure and Fail Safe.
