SECURITRON TIMEMATE MODELS TM-9
INSTALLATION AND OPERATING INSTRUCTIONS
1. DESCRIPTION
The TimeMate is a miniature “off delay” timer which operates on 12 VDC, 24 VDC or 24 VAC
and provides a digitally set delay time of up to 35 seconds. The TimeMate has a 3 Amp SPDT
relay output. When the trigger wire (YELLOW) is closed to the +V input (RED), the relay
energizes. As long as the trigger wire is receiving +V, the relay remains energized but timing
does not begin. When +V power is removed from the trigger wire, the relay remains energized
until the set time expires (off delay function). At that point, the relay deenergizes until the next
trigger operation. Note that the TM-9 is retriggerable. This means that if the trigger wire
receives power in the middle of a timing operation, the relay stays energized while the previous
timing cycle halts. When power is removed from the trigger, a new timing cycle begins. As long
as trigger events keep occurring prior to a cycle timing out, the relay stays energized.
The most common application for the TimeMate is as a "pulse extender". There are many
situations where a momentary manual switch closure is used to control a device and also where
the operation must be extended for an amount of time. Operation of the switch activates the
TimeMate, whose relay then engages or releases the device for up to 35 seconds. It is as if the
switch was held for that amount of time.
A common application is to have a keyswitch or push button mounted in an outlet box whose
function it is to release an electric lock. Without the TimeMate, use of the door is a 2 handed
operation. The switch is operated with one hand and the door is pushed open with the other.
When the TimeMate is added, momentarily operating the switch releases the lock for enough
time for a person to conveniently move through the door.
Integration with an outlet box mounted switch is the reason for the TimeMate being packaged in
a miniature plastic box. In most cases, the TimeMate can be installed in the outlet box with the
switch. Alternately, the TimeMate may be mounted on the rear, top or side of the outlet box
using the supplied double stick tape.
2. OPERATION AND WIRING
The TimeMate requires 12 VDC, 24 VDC or 24 VAC for operation. It will not operate on 12
VAC. It draws no current when “at rest” and 27 mA @ 12v or 38 mA @ 24v when the unit is
timing. It is most convenient to operate the TimeMate on the same power supply that operates
the electric lock or other load. DC voltage need not be regulated (transformer + bridge rectifier
is acceptable.)
Voltage selection and time setting are all accomplished by use of the five dip-switches which
are accessible on the unit. Dip-switch #5 selects the voltage: ON=12V; OFF=24V. Be sure
you set this switch correctly as the unit will be damaged if it is set for 12 volts and operated
on 24.
Four drawings are shown on the other side of this sheet. The first shows general operation of
the unit which is valid for a broad range of uses. The second shows wiring for control of electric
locks. Note that you use the blue or green wire for lock hookup depending on whether the lock
is fail secure (released when energized) or fail safe (secure when energized). Note also that
this connection is valid only when the same power supply operates the TimeMate and lock.
The third drawing shows a more reliable way of wiring DC fail safe locks. We call this "double
break" wiring. It does require the use of an SPDT switch as the drawing shows. Power to the
lock is routed through the switch's NC contacts as well as through the TimeMate's NC relay
contacts. When the TimeMate is triggered from the switch's NO contacts, the relay breaks
power to the lock. The switch itself also breaks power to the lock which is why this connection
procedure is called "double break". The advantage is that should the timer fail for any reason,
the door can still be released from the switch for 2 handed exit until the timer can be replaced.
