ENFORCER 365-Day Annual Timer
Features:
Introduction:
The ENFORCER SA-027HQ Annual Timer can be programmed to operate two relays 24 hours a
day, over the course of an entire year. These relays can be used to control devices in many
applications such as security, access control, lighting, and environmental control. The two Form C
relays can each be programmed to operate in shunt or momentary mode for up to 50 unique
events. Each event can be programmed on a weekly or daily schedule. Block programming allows
events to be repeated on consecutive days. 10 Programmable holidays disable the timer for a
single day, or for the same day every year.
Two N.O. or N.C. Form C relays 10A@14VDC.
Each relay can be programmed for 50 events, for a total of 100 individual programmable events.
The 100 programmable events can be set weekly, daily, or hourly, over the course of an entire
year.
Password protection can be turned ON or OFF.
One egress input per relay (2 total).
Block programming allows events to be repeated on consecutive days.
First-person-in function interrupts the normal operation of the annual timer.
Event outputs can be programmed disable, ON, OFF, shunt, or momentary (1~99 seconds).
10 Programmable holidays.
Can be programmed for password protection.
Tandem mode allows both relays to operate simultaneously.
EEPROM Memory for safe data protection in case of power failure.
Built-in clock backup battery.
Built-in backup battery charger for external backup battery use.
Compensates for leap years.
Can be set for Standard or Daylight Saving Time.
Alphanumeric backlit LCD display for easy programming.

Specifications:
1. Find a location for the SA-027HQ where the LCD display is easily seen and the buttons can be
pressed. Mark that location.
2. Open the case and connect the wires.
3. Connect a 12/24 VDC/VAC power supply to the power input terminals marked (+) and (-).
4. Connect the battery backup to the backup battery input terminals marked (+) and (-).
NOTE: For the best backup battery charging results, the power input should not be lower than
17VDC or 12VAC.
5. Remove the paper battery protector from the onboard clock backup battery.
NOTE: The paper protector prevents the battery from being drained during product shipment. If
the protector is not removed, the onboard clock backup battery will fail to function.
6. Connect the devices that are being controlled to the outputs of one or two relays.
NOTE: If using a DC-powered electric/electromagnetic lock, connect a 1N4004 diode in parallel
with the power supply and as close to the lock as possible. This absorbs possible interference
and prevents operation of the lock from damaging the timer. Not required for AC-powered locks.
7. Close the case and mount the unit.
Installation:
The SA-027HQ has 4 function buttons that control the programming features.

1. Following the programming instructions in order will make installation easier.
2. Determine which relays will operate the devices that are being controlled.
3. Determine if two relays will be used in tandem.
4. Determine if Daylight Saving Time or Standard Time will be used. For a full explanation, see
Setting Block Programming and Time Settings on page 8.
5. Using a separate piece of paper, write down the following:
a. The days to be block coded. For example: Monday through Friday or Sunday and Monday.
b. All the events you want to program, as well as their duration (up to 50 per relay).
c. Any holidays you wish to program to override the programmed events (up to 10).
6. Decide whether you will use a password or not, and what the password will be. For password
operation, see page 9.
7. To reset the password, see Password Reset on page 9.
A convenient feature of the SA-027HQ Annual Timer is the ability to program it before installation.
The EEPROM memory stores and protects programming instructions.
Programming the SA-027HQ is easier and faster if you know exactly how you want to use the
Annual Timer, as well as functions it will perform.
