＊ Note:
1. Terminal 31&32
Building fire alarm panel needs to provide dry contact (N/C) connection with minimum capacity of 24VDC and 0.08 amp. To have
5.16 ohms max line impedance.
2. Terminal 32&33
Use this connection to notify release device the status of the door. Field installation of microswitch on the door is necessary to use
terminal 32&33.
When the door is already in its close position, a closed contact (N/C) can cause the release device not to release (5.16 ohms max
line impedance). Power failure will still cause the solenoid to let go, hence resetting is necessary.
3. Terminal 35&36
This connection provides 24VDC, 0.23A power with 18AWG wire for maximum of 20 ft., when release device has been released.
This can be used to provide power for warning devices. The warning power is provide for less than a minute. The wiring
connections are enclosed within conduit or equivalently protected against mechanical injury.
