Outputs
The Controller has 7 onboard outputs which can be 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.
Bell/Siren Output
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.
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 two 1K resistors in parallel.

Bell Siren Connection
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 (see page 43) will be activated. This
can be avoided by connecting a 1K resistor 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.
Relay Outputs
The Relay Outputs (CP001:03 and CP001:04) on the Controller are Form C relays having normally open and
normally closed contacts. These outputs can be used to activate larger relays, sounders, lights, or locks etc.
