in4004 diode
Hi,
I am working with a fire fighting system control panel, and I have a problem in the panel output.
the out should be connected to a solenoid to control opening the extinguisher as in picture

the diode is connected to prevent transients made by solenoid coil from entering cct.
PROBLEM IS : this diode brings the 24 output to (only 0.6 volts) which is not enough to operate the solenoid????
I can remove this diode ....but what about coil spikes??? need your advise.
