PIEZO SOUNDERS DC, with circuitry

Loud sounders that may be powered with a voltage of anywhere from 3.0 to 20VDC. Output minimum

95db at minimum voltage; 105db at 20 volts. Sound frequency is 2.8Khz µ0.5Khz. Typical current draw

is 6mA @ 6V DC; 10mA at max. voltage. ABS case meets UL94HB, lead wires are UL listed materials.

No other circuitry is needed, just DC voltage. Mounting ears are on centers of 50mm, case diameter is

42mm O.D. Available with continuous tone, on/off tone and with hi/lo dual tone.

# B818 = Continuous
# B819 = On/Off
# B820 = Hi/Lo

 

Miniature DC Buzzers

This series of single tone, magnetic buzzers provides a minimum sound pressure (at rated voltages) of
75db. Small and compact, with pigtail leads for connections. No moving contacts to produce
arcing, no RF noise. Low current requirements* and very economical. Maximum width and length are:
0.630” and 1.30”

* Stock number B816 draws a maximum of 20 milliamps; all others draw a maximum of
15mA at the rated voltages.

# B814 = 3 vdc
# B816 = 6 or 9 vdc
# B822 = 9 vdc
# B812 = 12 vdc
# B824 = 24 vdc

Invisible pulse beam effective up to 50 feet--not affected by outside lighting changes Unlike most other

one-piece relay systems, this unit is capable of: 1. Tying in directly to any burglar alarm system. 2.

Operating 12 volt DC devices (such as sirens, bells, counters) up to 1 amp current. 3. Operating 120

volt AC devices drawing up to 3 amps. Six modes of operation are ready selected by slide switches

on the rear panel: 1. LOCK - Stays on until reset. 2. INSTANT - Actuates only when beam is

intercepted. 3. INTERMITTENT - Actuates for five seconds after beam is broken.

PLUS NORMAL and REVERSE on any of the above:

NORMAL - Power on when beam is broken
REVERSE - Power off when beam is broken
No bulbs to replace - it doesn’t use any. Long life LED provides the pulsed infrared beam.
Supplied with universal mounting brackets to allow installation on walls, floors, ceiling, flush mount and high efficiency reflector. A built-in LED monitor lamp denotes perfect alignment between the unit and the reflector furnished.
