Product details
PA4 is a Grade 3, 12VDC powered, confirmable PA for use in installations where accidental or false activations are a concern.
In confirmable mode, either set of buttons will switch the first output, and the alternate set of buttons will switch the second output. This sequence is followed regardless of which set of buttons is pressed first, though there is a shunt option that maps each set to a specific output. A fully activated unit can be reset with the included key. A partially activated unit can be reset this way too, or automatically via a 12-hour period of idle time.
All wiring is done on a PCB fitted with 8x wire-clamping terminal blocks. A sprung microswitch acts as the lid tamper, with a breakaway tamper to detect removal from the fitting surface. As the device is powered, a shunt option for a comfort/heartbeat LED is present for user reassurance.
As well as a volt-free, resistorless, dry wiring option, PA4 also includes a variety of onboard resistors on both outputs that are selectable by shunt link:
