120 Module 127: Protege DIN Rail Hardware Configuration | DIN Rail Hardware Setup
Outputs
The Controller has 7 onboard outputs. Outputs are used to activate sirens, bells, warning devices, control
lighting and doors. The first output on the Controller has a special hardware design that allows it to monitor for
fault conditions and is ideally suited to driving sirens or warning devices.
The + and - terminals of the Bell output (CP001:01) are used to power bells, sirens or any devices that require a
steady voltage output. The bell output supplies 12VDC upon alarm and supports one 30-watt siren. The bell
output uses an electronically fused circuit and automatically shuts down under fault conditions.

If the load on the bell terminals returns to normal, the controller reinstates power to the bell terminals on the next
transition of the output.
When the bell output is not used, the appropriate trouble input will be activated. This can be avoided by
connecting a 1K resistor (provided in the accessory bag) across the bell output. If the bell is not being used for
another function, and the trouble input is not programmed in the system, a resistor is not required.
Connecting a Piezo siren may result in a dull noise being emitted. This is caused by residual current from the
monitoring circuit. To prevent this occurring, connect 2 1K resistors in parallel.
The Relay Outputs (CP001:03 and CP001:04) on the controller are normally open relay outputs. These outputs
can be used to activate larger relays, sounders and lights, etc.

Warning: The Relay outputs can switch to a maximum capacity of 7A. Exceeding this amount will damage the
output.
