SARGENT TIME DELAY TMR2 MULTI FUNCTION TIMER
INSTALLATION AND OPERATING INSTRUCTIONS
1. DESCRIPTION
The TMR2 is an industrial quality multi-function timer that operates on 12 or 24 volts, AC or
DC. Its outputs are 5 Amp DPDT relay contacts and a unique flashing voltage output
described in section 5. Delay time is set in seconds or minutes up to a maximum of 255
minutes. While developed for the security industry, its comprehensive range of features
makes it suitable for broad use in many applications.
2. TIMER POWER
The timer is powered by 12 or 24 volts AC or DC on the power input terminals shown in
Figure 1. If DC power is used, correct polarity must be followed. The timer is factory
set to operate on 24 volts. If 12 volts is supplied, the H/L Dip Switch must be set to
the "L" position (on). Power consumption depends on whether the relay is energized or
not. Maximum draw is 100 mA at 12 or 24 volt operation.

3. TIME SETTING
One of the outstanding features of the TMR2 is that the delay is set digitally instead of by a
pot. This permits accurate time setting without the need for trial and error which is a
lengthy process with the longer time ranges.
2 time ranges are possible: 1-255 seconds or 1-255 minutes. The unit is factory set for the
seconds range. If you require minutes, a Dip Switch must be changed (see section 4.1).
The exact time is then set from the 8 position Dip Switch which displays binary numbers
from 1 to 128. If you turn an individual switch on, the time will be set for that exact value.
Turning more than one switch on adds the value of the switches selected. By combining the
switches as necessary, any exact value between 1 and 255 can be set. To quickly calculate
the switches to turn on, start with turning on the largest value less than the time you want
to set. Then subtract the value you turned on from the time you want and turn on the next
largest value switch. Continue this process until you have exactly set the required time.
For example, if you require 53 seconds, first turn on the Dip Switch marked 32 (the largest
value under 53). Subtracting 32 from 53 yields 21. Then turn on the Dip Switch marked 16.
Subtracting 16 from 21 yields 5. Turn on the Dip Switch marked 4 and then the one marked
1. You will have 4 switches on: 32, 16, 4 and 1. These numbers add to 53.
