Elapsed Timers and Code Blue Timers include a three button Timer Control Switch that controls its timer events.
The wiring is dependent on the type of code blue system identified below.
For code blue systems that apply a voltage to start a code blue event.
Wire the timer 4 pin connector's RED (Positive Code Blue Input) and BLACK (Negative Code Blue Input) wires to the code blue system. Cap off the WHITE and GREEN wires separately.
An input voltage of 5-120V (AC or DC) can be used. When using DC, be sure to use the correct polarity; RED wire is positive and the BLACK wire is ground. Code Blue start/stop events are triggered by the application of voltage across the code blue input wires.
For code blue systems that use a dry contact and do not inject a voltage
Wire the timer 4 pin connector GREEN (Ground) and BLACK (Negative Code Blue Input) wires together and wire the WHITE (12VDC) and RED (Positive Code Blue Input) wires to the code blue system dry contact.
The timer control switch is not connected to the timer during shipment.
Using the supplied 14 ft. (4.3 m) Rj11 cable connect the timer to the timer control switch. The cable length can be extended up to 100 ft. (30 m).
