Securitron TM-2 – Frequently Asked Questions
1) What voltage does the Securitron TM-2 Time Master II timer run on?
The TM-2 runs on 12 or 24 volts, either AC or DC, so it drops onto most access control power supplies without a separate transformer. Output is a 5A DPDT relay, which gives you two independent sets of contacts to drive a lock and signal a panel or alarm input at the same time.
2) How long a delay can the Securitron TM-2 timer be set for?
Delays are set with DIP switches from 1 to 255, in either seconds or minutes, so the range runs from a one second pulse up to over four hours. Increments stack, which is why it gets used for unusual sequences like bank and ATM vault timing rather than simple door release delays.
3) Can I trigger the TM-2 timer from a normally closed contact, or does it have to be normally open?
Either one. Triggering works from an N/O or an N/C switch, so you can drive it from a request-to-exit button, a card reader output, or a door position switch without adding an inverting relay.
4) What is the difference between the Securitron TM-2 Time Master II and an Aiphone RY-PA door release relay?
They do different jobs. The Securitron TM-2 Time Master II is a multi-function timer with a 5A DPDT relay output whose DIP switches set delay times from 1 to 255 seconds or minutes, and it runs on 12 or 24 VAC or VDC, so it is used where an output has to be held, delayed, or sequenced for a set interval. The Aiphone RY-PA is a door release relay for the LEF series intercoms, rated 12V DC with a normally open output, so it simply switches a door release when the intercom calls for it. If you need a timed or sequenced output, the TM-2 is the timing device; if you only need an intercom station to drop a strike, the RY-PA is the door release relay.
5) Will the Securitron TM-2 hold up in an unheated garage or a mechanical room?
Rated for +32 to +149F (0 to +65C), so an unconditioned interior space or a warm equipment room is fine. Below freezing it is outside the stated range, so an exterior enclosure in a cold climate needs heat.
6) Can one TM-2 timer switch two circuits at once?
Yes. The output is a 5A DPDT relay, meaning two independent changeover contacts. One pole can drop power to a maglock or strike while the second signals a panel, sounder, or camera trigger. Each pole gives you both a normally open and a normally closed contact to wire against.
7) Can an Aiphone RY-PA be used instead of a Securitron TM-2 where a timed door release is required?
No. The Aiphone RY-PA is a normally open door release relay for LEF series intercom systems and switches on command only; it is not a timing device. The Securitron TM-2 Time Master II is the part that supplies the interval, with DIP switch selected delays of 1 to 255 seconds or minutes and a flashing LED showing remaining time. On an intercom door that also needs a held or delayed release, the RY-PA and the TM-2 address separate parts of the circuit rather than replacing one another.
8) I need a relay that will work on a 24V access control power supply - will the Aiphone RY-PA do it, or do I need the Securitron TM-2?
The Aiphone RY-PA is specified as a 12V DC relay, so a 24V supply is outside what it is listed for. The Securitron TM-2 Time Master II accepts 12 or 24 VAC or VDC and provides a 5A DPDT relay output, which gives you both contact sets and either voltage on a commercial access control power supply. For a 24V system the TM-2 is the one built to take that input.
9) How do I know the TM-2 timer is actually counting down during a sequence?
A flashing LED on the board shows remaining time or alert status, so a technician can confirm the unit triggered and is timing without putting a meter on the relay contacts. That matters on long delays where nothing visible happens at the door for minutes at a time.
10) Is the Securitron TM-2 suitable for a commercial building install?
Yes, it is a commercial-grade access control component, built as an industrial duty multi-function timer for delay or time sequencing. Typical uses are door delay circuits, timed relock, and sequenced openings such as vault and mantrap arrangements.
