Outputs

The PRT-WX-DIN has 7 onboard outputs that can be used to activate sirens, bells, warning devices, control lighting and doors. The first output on the two controllers have a special hardware design that allows them to monitor for fault conditions and are 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 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.
