EXTERNAL TEST LAMP UNIT
LAM-612P
Description
Designed to test the RIV-601P/S spark detector window integrity
against dust and dirt build-up.
Its use is recommended when internal test cannot be reliable
because of window being covered or darkened.
Its mounted like a spark detector, using the same SAM-871
mounting unit, over the duct in the opposite position, so as it will
be in front of the spark detector.
The LAM-612P unit includes an incandescent bulb whose light is
made pulsing by a modulator circuit at a particular frequency
which is recognised by the spark detector.
On the LAM-612P terminal block wiring is on the same
- and T+
terminals (5-6) as on RIV-601P/S spark detector.
Specifications
Cast aluminium case with IP66 protection (dust and water spray).
