Auxiliary Outputs
Each telephone includes two isolated solid-state switches capable of switching a maximum of 125 mA at
48 V dc or 80 mA at 28 V ac.
TB2
(
OUT1
) and
TB5
(
OUT4
) on the emergency telephone PCBA
provide the connections for the auxiliary outputs (see Figure 9).
Auxiliary Output Control
Output one connects to terminal block
TB2
on the telephone’s PCBA (see Figure 9). This output closes
when the

push button is pressed and remains in that state for the duration of the telephone
call.
Output one can be programmed to remain closed for up to 255 minutes (in 1-minute increments) after the
call ends. The output can be deactivated before the call is disconnected via an external switch or by
pressing
*921 on the keypad of the called telephone. The Clean Phone

analog telephone acknowledges
acceptance of the deactivation command with a short beep. Retry the command if the beep is not initially
received.
Output four connects to terminal block
TB5
on the telephone’s PCBA (adjacent to
TB2
). This output is
remotely controlled by a DTMF command issued from the called telephone. This remote-control output
can be used to activate or control a door latch, gate relay solenoid, alarm, etc. from the called party
location (see Figure 9).
