7.0 Programmable Outputs
The Protégé® SE Integrated System Controller has 8x Programmable Outputs (PGM’s). The PGM’s
are used to acvate sirens, bells, warning devices, control lighng and doors. The rst 2 PGM’s on
the Protégé® SE Integrated System Controller have special hardware designs that allows them to
monitor for fault condions and are ideally suited to driving sirens and warning devices.
7.1 Bell/Siren PGM Outputs
The + and - terminals of Bell 1 (PGM1 CP001:01) and Bell 2 (PGM2 CP001:02) are used to power
bells, sirens or any devices that require a steady voltage output. The Bell Outputs supply 12VDC
upon alarm and support one 20-wa siren. The Bell Output uses a electronically fused circuit and
automacally shuts down under fault condions.
If the load on the bell terminals returns to normal, the Protégé® SE Integrated System Controller
reinstates power to the bell terminals on the next transion of the output.
?
When the Bell Output is not used, the appropriate trouble zone will be acvated
(refer to the Trouble Zones secon on page 21). To avoid this, connect a 1K resistor
(provided in the accessory bag) across the Bell Output. If the bell is not being used
for another funcon, and the trouble zone is not programmed in the system, no
resistor is required.

Connecng a Piezo Siren may result in a dull noise being emied. This is caused by
residual current from the monitoring circuit. Connect 2x 1K resistors in parallel to
prevent this from occurring.
