Seco-Larm’s Request-to-Exit Plates with Pneumatic Timers do not require power to operate them. Because of their completely passive operation, these plates are ideal for installations where supplying additional timer power is convenient. The timers are MET recognized, made from American-made pneumatic components, and are adjustable from 1 to 60 seconds. Enforcer Request-to-Exit Plates with Pneumatic Timers are available with a slimline or single-gang plate, and with a mushroom cap button or a button with guard ring. Each unit has the words “Exit” and “Salida” printed onto the plate.
