For all EOL types, a resistance below 300Ω is considered a short. If the resistance is not within the
thresholds stated, this is treated as a disconnection.
10.6 Wiring an external SAB bell
On an external bell to the SPC controller board the relay output is wired to the strobe input with Bell Hold
Off (BHO) and Tamper Return (TR) connected to their respective inputs on the external bell interface.
A resistor (2K2) is pre-fitted on the controller board between the BHO and TR terminals. When wiring an
external bell, connect this resistor in series from the TR terminal on the controller to the TR terminal on the
external bell interface.
