Figure 7 Wiring diagram for 3-wire connection
In order to comply with regulations for device and wiring supervision it may be necessary
to use an end of line relay and end of line resistor. Also the contact across the detection
zone for fire is a relay contact and it will generally be necessary to include a resistor or
other current limiting element in series with the relay contact.
Because the beam detector is powered by a separate line from the control panel it will be
necessary to reset this power line to remove a fire condition from the beam detector.
The connections for the emitter and receiver are detailed below. The terminal names are
marked above the terminals on the beam detector. Refer to section 4 for a drawing of the
terminal positions.
Emitter:
E1, E2 Zone or Power (in/out) (Non Polarized)
Receiver:
F1, F2 - Fire alarm output contacts. Normally open
T1, T2 - Fault output contacts. Normally closed
24V, 0V - Beam detector power supply
Now set up the beam as described in sections 2.6 and 2.6.2.
