Low-Power CMOS
ALARM IC with Horn Driver
14600
The MC14600 Alarm IC is designed to simplify the process of interfacing an
alarm level voltage condition to a piezoelectric horn and/or LED. With an
extremely low average current requirement and an integrated low battery detect
feature, the part is ideally suited to battery operated applications. The MC14600
is easily configured with a minimum number of external components to serve a
wide range of applications and circuit configurations. Typical applications include
intrusion alarms, moisture or water ingress alarms, and personal safety devices.

1. Maximum Ratings are those values beyond which damage to the device may occur.
This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised normal
precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. For proper
operation, it is recommended VIN and VOUT be constrained to the range VSS ≤ (VIN or VOUT) ≤ VDD
.

DEVICE OPERATION
power strobed and thus gives constant protection from
Timing
The internal oscillator of the MC14600 operates with a
surface leakage currents. Pin 15 (the Detect input) has
internal diode protection against static damage.
period of 1.65 seconds during no-alarm conditions. Each
1.65 seconds, internal power is applied to the entire IC and a
check is made for an alarm input level except during LED
pulse, Low Battery Alarm Chirp, or Horn Modulation (in
alarm). Every 24 clock cycles a check is made for low battery
by comparing VDD to an internal zener voltage. Since very
small currents are used in the oscillator, the oscillator
capacitor should be of a low leakage type.
Low Battery Threshold
The low battery voltage level is set internally by a voltage
divider connected between VDD and VSS. This voltage can be
altered by external resistors connected from pin 3 to either
VDD or VSS. A resistor to VDD will decrease the threshold
while a resistor to GND will increase it.
Alarm Threshold (Sensitivity)
Detect Circuitry
The alarm condition voltage level is set externally through
Pin 13. A voltage divider can be used to set the alarm trip
point. Pin 13 is connected internally to the negative input of
the detect comparator.
If an alarm condition is detected, the oscillator period
becomes 41.67 ms and the piezoelectric horn oscillator
circuit is enabled. The horn output is modulated 167 ms on,
83 ms off. During the off time, alarm detect input (Pin 15) is
again checked and will inhibit further horn output if no alarm
condition is sensed. During alarm conditions the low battery
chirp is inhibited, and the LED pulses at a 1.0 Hz rate.
An active guard is provided on a pin adjacent to the detect
input (Pin 16). The voltage at this pin will be within 100 mV of
the input signal. Pin 16 will allow monitoring of the input signal
at pin 15 through a buffer. The active guard op amp is not
.
LED Pulse
The 9-volt battery level is checked every 40 seconds
during the LED pulse. The battery is loaded via a 10 mA
pulse for 10 ms. If the LED is not used, it should be replaced
with an equivalent resistor so that the battery loading remains
at 10 mA.

NOTE:
1. Horn modulation is self-completing. When going from Alarm to No Alarm, the alarm condition will terminate only when
horn is off.
2. Comparators are strobed once per cycle.
3. Low Battery comparator information is latched only during LED pulse.
