System Sensor SPSCWLED-CLR-ALERT is an L-Series with LED 2-wire speaker strobe for indoor ceiling mounting, with a white housing, ALERT marking and clear lens. It combines a 25 or 70.7 VRMS speaker for voice and tone signaling with a low current LED strobe, suited to mass notification and emergency communication systems that use ALERT-marked appliances.
Rotary switches set candela, speaker voltage and power tap. The universal mounting plate has a plug-in design and an onboard shorting spring to check wiring continuity before the device is installed, and digital voltmeter test points on the face allow voltage checks without removing the appliance.

FAQ
Which candela settings does the ceiling model have?
15, 30, 75, 95, 115, 150 and 177 cd, set with a rotary switch. The 110, 135 and 185 cd settings apply to wall models only.
Which power taps are available?
1/4, 1/2, 1 and 2 W at 25 or 70.7 VRMS, giving 76 to 83 dBA reverberant at 10 ft.
Will it work with existing System Sensor appliances?
Yes. It is electrically compatible with legacy SpectrAlert, SpectrAlert Advance and L-Series devices at 16 to 33 VDC.
Is a surface back box available?
Yes. The SBBCWL ceiling surface mount back box fits it; with the back box the depth is 4.83 in.
