19 Protégé System Controller Installation Manual
PROGRAMMABLE OUTPUTS
Introduction
The Protégé System Controller has 4 Programmable Outputs (PGM's). The PGM's are used to
activate sirens, bells, warning devices, control lighting and doors. The first 2 PGM's on the
system controller have special hardware designs that allows them to monitor for fault
conditions and are ideally suited to driving sirens and warning devices.
Bell/Siren PGM Outputs
The + and - terminals of Bell1 (PGM1 CP001:01) and Bell2 (PGM2 CP001:02) are used to
power bells, sirens or any devices that requires a steady voltage output. The bell outputs
supply 12Vdc upon alarm and support one 20-watt siren. The bell output uses a electronically
fused circuit and automatically shuts down if the current exceeds 1.8A.

If the load on the Bell terminals returns to normal ( ≤ 1.8A), the Protégé System Controller
reinstates power to the Bell terminals.
When the bell output is not used, the appropriate trouble zone will be activated
(refer to the Trouble Zone Input section on Page 17). To avoid this, connect a 1k Ω
resistor (provided in the accessory bag) across the bell output. If the Bell is not
being used for another function, and the trouble zone is not programmed in the
system, no resistor is required.
PGM3/4 Outputs
The PGM outputs 3 (PGM3 CP001:03) and 4 (PGM4 CP001:04) on the Protégé System
Controller are open collector outputs and switch to 0V.
The PGM's can be used to activate relays, sounders and lights.
