AL100H Alarm Horn Sounder & LED Beacon

The AL100H features the 104dB(A) A100 alarm horn sounder combined with the L101H high output L.E.D. beacon. The compact, robust housing is ideal for all general signalling applications including fire, security and process control.

The array of 24 Superflux type high output L.E.D's generates over 120 candela of light output and can be user set to either steady of flashing mode. Sounder & beacon may be connected from a single supply for simultaneous operation or from separate supplies for independent operation.


Maximum output: 104dB(A) @ 1 metre [95dB(A) @ 10ft/3m]
Nominal output: 100dB(A) @ 1m +/- 3dB - Tone 2 [91dB(A) @ 10ft/3m]
No. of tones: 32 (UKOOA / PFEER compliant)
No. of stages: 3
Volume control: Max. 100dB(A); Min. 90dB(A) - Tone 2
Effective range: 32m/105ft @ 1KHz
Stage switching: Negative
Reverse polarity stage switching on DC units.
Light source: High intensity L.E.D. array.
24 x Superflux type high ouput L.E.D’s
Options: Steady or 2Hz flash mode
(on board selection)
Peak/Effective Intensity cd: Green L.E.D: 176cd - measured ref. to I.E.S.
Terminals: 0.5 to 4.0mm² cables
L.E.D. colours: Amber Blue, Green, Red and White
Lens colour: All L.E.D. colours use a Clear lens to maximise output and to ensure the signal is most effective in high ambient light.
Voltages DC: 24V dc (10-30V dc); 48V dc (35-60V dc)
Voltages AC: 115V ac; 230V ac
Ingress protection: IP66
Housing material: High impact UL94 V0 & 5VA FR ABS
Colour: Red (RAL3000), grey (RAL7038) & white.
Cable entries: 4 x M20 clearance gland entries in side & back
Terminals: 0.5 to 1.5mm² cables.
Operating temp: -25 to +55°C [-13° to +131°F]
Storage temp: -40 to +70°C [-40° to +158°F]
Relative humidity: 90% at 20° [68°]
Weight: DC: 0.46kg/1.01Ibs AC:0.57kg/1.25Ibs
*Candela measurements representative of performance with clear lens at optimum voltage.
*SPL data +/-3dB(A). Measured at optimum voltage.
