gamewell fire alarm 1961 using teletype, low voltage want to control 110 vac lights and horn.
The relay on the alarm is controlled when lever is pulled down running and mechanical timer with tooth wheel that turn on and off relay. The relay opens the circuit low voltage is dropped then turned on to give alarm location.
I want to add 110 vac light and horn using a relay to control 110 vac. with 12 vdc for the low voltage.
The problem is when the timing wheel stops the contacts are closed on the alarm.
Need a relay that will power up the 110 vac as the points on the alarm closes and disconnect when the points open, then disconnect when the alarm timer stops ( the points close at the time)
Help finding the right controller or relay and wiring diagram (may need time)
