SECURITRON TIMEMASTER MODEL TM-2 MULTI FUNCTION TIMER
INSTALLATION AND OPERATING INSTRUCTIONS
1. DESCRIPTION
The TimeMaster is an industrial quality multi-function timer that operate s 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 TimeMaster 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 swit ches 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.

4. DIP SWITCH SETTING
There are a total of 13 Dip Switches on the TimeMaster. The first 8 marked with binary numbers
are for time setting and are explained in section 3. The next 5 select functions as follows:
4.1 SW1: TIME UNIT SETTING
In the factory set condition (off), the time value set on the 8 time setting Dip Switches is
expressed in seconds. Turning the switch on allows time setting in minutes.
4.2 SW2: TRIGGER SWITCH LOGIC
Several of the operating modes (off delay, toggle and pulse output) require triggering from an
external switch. The switch connects the trigger terminal (T) to the board's "+" terminal. In the
factory set position of SW2 (off), a normally open external switch is used for triggering so that
when terminal T is closed to terminal "+", the timer is triggered. Turning the switch on
permits the use of a normally closed external switch. When the connection between terminal T
and "+" is broken, the unit is triggered.
4.3 SW3 AND SW4: MODE SETTING MATRIX
These switches are set in a matrix yielding 4 different operating mode s for the TimeMaster. The
factory set position is on delay. The modes are described in detail in section 6. The matrix
settings are:
SW3 ON; SW4 ON: ON DELAY MODE
SW3 OFF; SW4 ON: ONE SHOT MODE
SW3 ON; SW4 OFF: TOGGLE MODE
SW3 OFF; SW4 OFF: OFF DELAY MODE
The TM-2 actually provides 7 different operating modes with methods other than Dip settings
being used to establish the other 3. Make sure you read the de scription of your mode in Section
6 as the setting of Dip Switches 3 and 4 is only part of the mode selection process.
