Before installing a control head on any cylinder
valve, ensure the control head is in the "SET"
position (e.g., actuating pin or plunger is on
the fully retracted or "SET" position.)
Electric control head P/N 48650001 is designed
for installation on a 487 or ECS series control
head only. Installation of this control head to
any other device (e.g., pressure operated
control head) will result in failure of device to
operate when control head is actuated.
All solenoid control heads must be removed
from the cylinders prior to testing to prevent
accidental cylinder discharge.
Notes on 24 Vdc Release Circuit
1. P/N 48650001 is a polarized control head. Improper
wiring will result in failure of device to operate.
2. The release circuit will activate for 90 seconds. At the
end of the 90 seconds the output will de-energize.
3. When resetting an alarm condition, the reset switch
should be depressed and held for five seconds to en-
sure smoke detector reset.
